The General Data Protection Regulation

The General Data Protection Regulation (GDPR) comes into force on the 25th May 2018 across the EU.


The regulation emphasizes transparency, security and accountability by data controllers, while at the same time standardizing and strengthening the right of European citizens to data privacy. The GDPR gives data protection authorities more robust powers to tackle non-compliance, including significant administrative fines. 


Within ISCYRA we process personal data as part of our activity, therefore we must seek express consent from people when we want to store their data. Data may include name, date of birth, address, contact details, likenesses, video and sound recordings and photographs. 

ISCYRA stores the personal data of its officers, committee officials, District and Fleet officers and others, and publishes this data on the ISCYRA website and in the LOG. 


Up to now, consent has been implied in that a person giving their details knew they would be published. That is no longer good enough.

Now, ISCYRA must be able to demonstrate that it has obtained clear written consent to the processing of any individual’s personal data for one or more specific purposes.


ISCYRA has contacted every Fleet officer to request consent to use their personal data and the data of their members for the legitimate purposes pursued by the ISCYRA. District and Fleet Secretaries should ensure that they are compliant with GDPR with respect to their own national associations.


Most NORs now state that photographs taken at the event may be used for publicity, and the Entry Form should contain a paragraph in which the Skipper (on his own behalf and on behalf of his Crew) gives explicit permission for any photos taken at the event (on and off water) to be used by the OA and ISCYRA.

The ISCYRA Privacy Notice is published under the Star Class tab on the website.

Any questions about this please contact the Executive Director

2018 Specifications

1.1. Important - In interpreting any point not covered, or wording of obscure meaning, the TAB shall consider the intended meaning, rather than any technical misconstruction that might be derived from the wording, and shall bear in mind at all times the basic principle of the specifications which is to maintain the Star within reasonable limitations as a standard one-design class.

1.2. Dimension and Weights in these specifications are in Standard International (S.I.) metric units, except that mass is usually called weight. When not otherwise specified, measurements of lengths are in millimeters (mm).

1.3. Requirements - A yacht, its spars and sails, must conform strictly throughout with respect to design, dimensions, construction, and material, to the official plans and specifications of the ISCYRA., subject to Class Rule 33, to be considered a Star and be eligible to the ISCYRA. THE ISCYRA'S MEASUREMENT CERTIFICATE IS THE ONLY RECOGNIZED PROOF OF ELIGIBILITY TO THE STAR CLASS.

1.4. Yacht's Number - Before a certificate can be issued, a yacht's number must be permanently affixed in not less than 51 mm figures in clear view.

1.5. Options - Nothing is optional in these specifications unless the word optional appears, and then only within the limitations described, in which case that which is mentioned is that which is recommended, in points of both safety and speed. Use of a substitute, even where allowed, is always at user's risk.

1.6. Materials.Wood:
As a guide in selecting materials, the following table indicates densities of woods specifically referred to in the articles below.
Weights with 15% moisture:
Mahogany 512 kg/m3
White Oak 712"

Plywood, veneer board, laminated woods, pressed wood, fiberboard, composition beard, balsa, cork, and woods without sufficient strength to hold fastenings shall not be used unless specifically mentioned.

1.7. Materials- Glass Reinforced Plastic (GRP):
Long strand glass fiber material may be used with a rigid, high strength resin, provided that the glass content of the combination exceeds 35 percent of the total by weight. Rigid, low density material, such as balsa, Aerolam, or plastic foam, may be used as a core between surfaces of fiberglass laminates. All materials used must have low absorption and high resistance to deterioration when in continuous contact with either fresh or salt water. Aluminum, Nomex, or other metallic honeycomb core materials are permitted, but only for use as flat panels such as are used for flotation bulkheads and other internal hull stiffening. Such materials are not approved for hull or deck core material.

Carbon fiber, Kevlar, R or S glass fibers or other exotic materials are not allowed in any new construction or repair of GRP or wood boats

1.8. Plan Approval - Glass Reinforced Plastic (GRP) Construction:
Pre-preg fibers in any combinations are not allowed, each builder's method of construction must be approved by the TAB prior to the start of construction. The submitted plans must contain enough detail to adequately describe all materials, attachments, and the local reinforcements as well as the general construction of the hull, deck and skeg. Pre-preg fibers in any combinations are not allowed.

1.9. Recommendations - The recommendations listed in the Specifications are based upon years of experience of many Star owners and builders.

All Measurements for location of rudder, keel, mast, jib downhaul, Point "B", stations, and length overall start from Point "T", the mid-point of the true transom which is the fair intersection of the outside planes of the transom and the deck exclusive of moldings. See 14, Limitations and the plans for dimensions. Point "B" is on the centerline of the boat, at the height of the top of the deck edge at the sizes, 4477 mm forward of Point AT". All deck measurements are taken exclusive of moldings. Measurements are to be taken of the truly faired shape of the hull. The use of bumps and hollows at measurement points is specifically prohibited.

3.5.4. RECOMMENDED - Sitka spruce.

3.6. Fastenings
3.6.1. Planking must be fastened to frames with screws, or serrated shank nails, but must be fastened to transom, stem, and joined at chine with screws. Glue and/or dowels shall not be substituted for metal fastenings.
3.6.2. OPTIONS - Any metal fastenings allowed.
3.6.3. RECOMMENDED - Silicon bronze screws.

4.1. Conditions- Regulations are imposed on the use of GRP construction to prevent attainment of unfair performance advantages from its substitution for wood in the structures of the yacht. In any case where there is a question as to the interpretation of these regulations, it is the responsibility of the builder to obtain a decision from the TAB prior to the start of construction.

4.2. Hull - With certain approved exceptions, the bottom, sides, and transom must be of a uniform structural mass throughout. The weight per unit area of any part of the hull, including a representative portion of any structure required to stiffen the surface, must equal or exceed 8.8 kg/m2. Thickness of the glass-foam-glass sandwich shall be sufficient to provide the flotation required by Section 7.

4.3. Deck - With certain approval exceptions, the deck must be of a uniform structural weight throughout. The weight per unit area of any part of the deck, including a representative portion of any structure required to stiffen the surface, must equal or exceed 5.4 kg/m2.

(Originally, GRP specifications were written in order to make GRP yachts comparable to those made of wood. With the exceptions of heavier frames and special braces, keelsons, etc., wood boats are "uniform" (i.e., uniform plank thickness and frame cross-sections). Accordingly, GRP (fiberglass) yachts are to be "uniform" in the basic lay-up of the hull and deck. The 8.8 kg/m2 required in the hull and the 5.4 kg/m2 required in the deck represent an average of the total weight including necessary stiffening. Thus the actual weight of a uniform lay-up for the purpose of uniform construction may be something less than the 8.8 kg/m2 (hull) and 5.4 kg/m2 (deck).

Because of the infinitely possible combinations of core materials, resin mixtures, different types of fiberglass cloth (weave and thickness), which would be satisfactory for Star construction, no specific lay-up has been written into the Specifications. Rather, it has been required that builders submit their construction plans and detailed lay-up schedule to be approved by the TAB before the builder begins construction. It is our view that the unit surface weight is self-limiting due to the need for hull stiffness and the constraint of overall hull weight. Too thin a surface would result in too much hull flexibility and inferior speed and durability. Too thick a surface will deprive the stiffening structure of the material required to make the boat rigid and have the same results. However there are certain conditions where either extreme might be advantageous and therefore it is essential to maintain the required uniformity. When plans are analyzed for approval they are viewed in this light. Any plan which deviates toward either of the two above extremes is rejected. All approved plans are on file in the Central Office along with sample lay-ups for the uniform construction. It is expected that these construction plans be followed by the builder and that any significant changes in the GRP lay-up that a builder may wish to use must be first approved by the TAB.

Secs. 4.2 and 4.3 provide for "certain approved exceptions" to the uniform construction. The practice of increasing the lay-up thickness and weight in addition to the uniform construction, along the bottom from slightly forward of the mast step to slightly aft of the rudder post is an approved exception. Other exceptions would include, but are not necessarily limited to: hull to deck joints, areas where special fittings are attached, bulkhead and stiffener attachments, etc. However, these items must be shown in sufficient detail as a part of or addendum to the plans before the plans receive final approval. –TAB, 1978)

4.3.1. DECK INSTALLATION - The deck must be attached to the hull in a manner which adequately resists the torsional forces in the hull and prevents the formation of leakage through the joint. The weight per unit area of any part of the joint must equal or exceed that of the surface in which the joint is made.
4.3.2. RECOMMENDED - A flush lap joint in the surface of the hull, cemented with a rigid adhesive resin and riveted.

4.4. Local Reinforcements - The hull and deck shall be reinforced as necessary to provide adequate support of the mast step, keel, skeg, rudder, cockpit opening and rigging. Such reinforcements may be in addition to the uniform mass of the hull and deck, provided that they are not so constructed to intentionally ballast the hull.
4.4.1. RECOMMENDED - Approximately 4.5 kg of structure should be allotted to these reinforcements.

4.5 Metal Inserts - Inserts of corrosion-resistant metal may be included as part of the hull and deck for attachment of rigging, tensile supports for the mast step, or attachment of normal equipment. Such inserts must be limited to the size and number necessary to perform their structural functions and must not be so constructed or arranged to intentionally ballast the hull. The tracks for running rigging and metal parts necessary to secure the keel to the hull are not to be considered as a part of the hull or deck.

5.1. Keelson - To be wood, 152 x 19 minimum length from Station 2 to Station 8. Shall weigh not more than 5 kg in GRP hulls.

(Length requirement does not apply if the aft edge of the keel forms the termination of the skeg.) The contour of the bottom of the skeg can at no point be more than 26 above or below a straight line between the maximum allowable depth and length points, and may not be concave, except that the skeg may be joined to the trailing edge of the keel with a fillet of no greater than 26 radius, and may extend downward a distance of no greater than 13 from a point no greater than 13 from the leading edge of the rudder. Depth of the skeg shall be measured to the extension of its bottom line, as if such downward extension did not exist.

In the event that the weight of the boat is less than this amount the difference shall be made up only by the addition of any material securely fastened to the underside of the deck. Material shall not be added or built-in to standard members or hardware for the sole purpose of obviating such correction.

13.2. In addition, the hull must comply with the following: The weight of the hull and attached deck must exceed 190.5 kg. If the skeg is also included, the weight of the total assembly must exceed 192.5 kg. Included with the hull in these weights are exclusively the chainplates, jibstay attachment fitting, the mast step with its supporting structure, built-in bulkheads and deck supports, a keelson (optional in GRP hulls), the rudder post tube and flotation.

13.3. If additional material is added to make up weight, as required by Section 13.1, such material shall be sealed by a Certified Measurer. The seal or seals applied shall be impressed or attached such that no part of the material can be removed without irreparable damage or destruction of the seal. Seals shall be distinctively marked for identification. If no additional material is required under Section 13.1, a seal as above shall be attached within the hull. A boat must bear such seal or seals to be in conformance with measurement rules.

In addition to the foregoing, there shall be permanently affixed to the after end of the cockpit coaming a plaque stating the amount of the additional material, if any, so affixed.

Yacht shall be measured on keel, with spars and rigging removed, or with rigging slack, and hull unsupported; and in accordance with instructions issued to Certified Measurers by the TAB. Measurements shall be recorded on the ISCYRA measurement form. Although only certain specific points on a Star are regularly measured and appear on the measurement certificate, it shall be thoroughly understood that any point may be measured, at the discretion of the ISCYRA TAB, and shall be in accordance with plans, specifications, and the following limitations.

14.1. Hull

Boat Dealers/Brokers


Rigging Information



Notice to Builders and Sailmakers


It is impossible to foresee every conceivable innovation which may be thought of in the future and to mention every suggestion that has been ruled illegal in the past. When considering anything in connection with the boat or its sails or equipment which is not within established practice in the International Star Class or is not clearly covered by plans or specifications, you must assume that it is illegal, and must obtain a ruling from the Technical Advisory Board before attempting it. 

Builders In order to obtain a license to build a Star boat, a builder must conclude a License Agreement with the International Star Class Yacht Racing Association (ISCYRA) and submit to the Technical Advisory Board (TAB) the following: 1. Hull Construction and lines drawing 2. Lay-up schedule and samples of lay-up 3. Drawing of keel, rudder and skeg 4. Construction of mast, boom and rigging. No number or measurement certificate can be issued until the above items have been approved by the TAB. If a builder changes his construction he is required to submit the concerned drawings or samples to the TAB for approval. After the License is granted no changes may be made to the hull, deck or keel shape without the licensee submitting a change order to the ISCYRA for approval. No change can be made without approval from the ISCYRA. New Construction Methods and Materials In keeping with the ISCYRA’s long standing policy of seeking more economical means of building yachts, it is believed to be in the best interests of the ISCYRA to actively seek new methods or materials while at the same time maintaining the competitive value of all existing yachts. To that end the following guidelines are intended for those members seriously interested in undertaking such developments, which will ultimately foster the growth of the ISCYRA. 

1. A member may request, in writing, permission to build one prototype yacht of non-specification materials and/or construction methods. His proposal should include a general statement regarding the estimated costs and benefits to be derived, drawings, sketches, etc. 

2. The Class Management Committee (CMC), acting with the advice of the TAB, will grant the builder the right to qualify for a provisional measurement certificate for a prototype yacht, provided that the following conditions are met: (a) Upon completion, the prototype yacht meets all specifications for hull shape, uniformity of construction and weight. Also flotation must be proved by test. (b) A full disclosure of the details of construction is made to the TAB including, among other things, scantlings, material specifications, special assembly techniques, photos of the construction process, and costs. 

3. The provisional certificate will authorize that prototype yacht to qualify for all races except Silver and Gold events. 4. Full disclosure of racing results and an analysis of same certified by a fleet or district officer are to be submitted to the CMC upon completion of a representative number of races. 

5. A final measurement certificate will be issued if the Class adopts that method of construction through its normal procedures of a fleet resolution, TAB approval, annual meeting approval and membership vote. Such approval will be granted provided that the construction of the prototype yacht does not vary to any substantial extent from the specifications finally adopted. 

6. On the recommendation of the TAB, a permanent measurement certificate may be granted to any specially constructed yacht by the CMC. 

Conditions Governing Sale of Plans and Specifications These conditions must be strictly enforced in the interest of keeping the Star a one-design class and to protect the prospective buyer of a new or second-hand Star from any intentional or unintentional misrepresentation concerning the boat's eligibility. This notice accompanies all official plans and is made a part thereof. It is the full text of the condensed agreement of sale that appears on each plan. 

Work only from official plans. Never copy the dimensions of another Star or its measurement certificate; sag or warpage of an old hull can be misleading, also the specifications are subject to occasional revision. 

AGREEMENT Whereas the International Star Class Yacht Racing Association (ISCYRA) owns all right and title to, and interest in, the design of a Star Class yacht and whereas official plans and specifications may be purchased conditionally from the ISCYRA; now therefore it is understood that the purchaser, by accepting and retaining the said plans, agrees to the terms and conditions herein: 

USE OF PLANS. Plans shall be used only in connection with the construction of Star Class yachts and their sails and accessories. The purchaser agrees not to resell, lend for publication or any other purpose, or transfer in any manner the plans or copies thereof, without authority in writing from the International Governing Committee (IGC) of the ISCYRA. 

INELIGIBILITY. Unless a yacht and its sails conform to the plans and specifications, within the allowed limitations, it shall be barred from the ISCYRA. The ISCYRA reserves the right to bar any yacht or sail constructed by a firm or individual who is not recorded with the ISCYRA as possessing official plans, or who fails to comply with any of the conditions herein. 

COST OF PLANS. Complete set of plans, $30; any single plan, $10; Rudder template, $20. Plans cannot be lent, nor sent on approval or credit. 

NUMBER TAX. Builders are required to pay a tax of $400 on each yacht built when applying for a number on Form R-1. A number will not be issued unless the yacht is actually under construction and the name and address of its owner are given. Yachts being built for stock should be reported but will not be issued numbers until complete and ready or measuring. For the purpose of identification, the number must be cut into the upper side of the keelson (or if the boat is fiberglass without a keelson, then cut permanently embedded at a location as near as possible to where they would be if the boat had a keelson), before the boat is measured. This number may be revoked if the yacht is not measured or is unable to obtain a certificate within a reasonable time. 

SAIL ROYALTIES. An ISCYRA sail royalty button must be permanently affixed to every mainsail and every jib. It is the obligation of the sailmaker to buy these buttons from the ISCYRA Central Office at $50 each. No sail can be used for racing without a button: it is not a Star sail unless the royalty button appears thereon. 

REMITTANCES. Remittances for all of the above must be made payable to and sent to the ISCYRA at its Central Office. Sums stated are in USA currency, net in the stated Account of the ISCYRA. 

KEEL WEIGHT CERTIFICATE. A keel weight certificate must be furnished by the builder to the measurer. It may be obtained from a public scale or such other source as the measurer will accept. 

REVISION OR SPECIFICATIONS. It is the responsibility of those who construct Star yachts or their sails or accessories to keep advised as to possible annual revisions of the specifications. 

Notice to Builders and Sailmakers

Measuring the Star Class Boat

The information in this section is provided by the TAB for those owners, builders, and fleet or regatta measurers wishing to understand the principles of ISCYRA measurement. Certified Measurers are provided with additional information, and have developed special measuring techniques, so one of them, or the TAB, can provide more detailed information than is presented here, if needed. 

PRINCIPLES OF MEASUREMENT Since the construction of a Star must conform to ISCYRA plans and specifications, and certain construction details require prior approval, the measurement procedure is a series of selected dimensional checks to ascertain that the boat actually conforms to the plans and specifications. Thus, measurement is a verification process, not a detailed physical description of the boat. When a new boat is completed, it is measured by a Certified Measurer. If his data indicate that the boat complies with the plans and specifications, the TAB will grant a Measurement Certificate, and the boat becomes eligible to the ISCYRA (STCR 33). 

Certain measurements are often required for entry in championship and other series, and non-sanctioned events, such as Olympic Regattas, may have special measurement requirements for eligibility (STCR 32). This type of measurement is conducted by appointed regatta measurers or the TAB. While regatta measurement requirements vary, the types of measurement and techniques used are the same as for certification measurement. 

There are for main categories of measurement: Measurement of Hull, Keel, Skeg and Rudder Measurement of Spars Measurement of Sails Weighing 

In each category, physical data are obtained by the measurer for comparison with allowable maxima and minima. 

MEASUREMENT OF HULL, KEEL, SKEG AND RUDDER Many of the Measurements in this category are taken on an imaginary three-dimensional grid whose position is specified. A base plane is established either optically or mechanically in an accurate position relative to the hull, roughly parallel to the waterline, and located a few centimeters below the hull bottom. Various height measurements are taken perpendicular to the base plane; most lengths and breadths are taken parallel to it. For example, "Keel Heights" are perpendicular distances from the base plane of specified points on the hull bottom. 

The Star is measured in an upright position, with base plane level and the hull supported on the keel (Spec. 14). Some flexion of the hull occurs due to its own weight in this position, but conditions are equalized for all boats measured. Certain critical keel and rudder post measurements are taken parallel to the base plane, so even if only these appendages are to be measured, an accurate base plane must be established. Measurements called for in the ISCYRA Regatta Measurement form, on the other hand, do not require the establishment of a base plane. 

Rudders are measured by use of a transparent template available from ISCYRA. Since rudder shape controls are referred to the hull, rudders cannot be properly measured off the boat (Drawing "F"). In addition to shape and height limitations, a minimum radius is specified for any curve of the rudder profile. Skeg measurements are described in Spec. 5.4. 

Because virtually every radius in the hull, keel, skeg and rudder is controlled, great care should be taken in fairing a Star that all radii remain in compliance with the controls. Radii can be checked with appropriate radius templates. 

Aid of non contact measurement instruments to define the dimensional checks conform to ISCYRA plans are allowed. 

MEASUREMENT OF SPARS Mast lengths are measured from Point "B", which is a point in the hull, not a point on the mast (Spec. 2). The distance in the hull from the mast step to Point "B" is measured and then transferred to the butt of the mast, and the required heights are checked. In fitting a new mast to a boat, care must be taken that the lower band is not less than the minimum height above Point "B", as well as observing height limits. 

Boom length is measured to the forward face, that is, the "bottom" of the luff groove in the mast. It is most convenient to measure this with the boom attached. Care must be taken that the measuring standard reach into the luff groove and touch bottom. 

MEASUREMENT OF SAILS Sails are measured to determine compliance with Specifications 12. As well as materials and all dimensions, sails are checked for numbers, insignia and honors, royalty labels, batten pockets, "windows", and all other items specified. 

When sails are measured for a championship series or other regatta, and found to comply, they are indelibly and distinctively marked by the measurer. Only sails thus marked may be used in the series. 

Drawings are provided in this section to assist in laying out measurement triangles and measuring sails. 

Several aspects of the Star are subject to weight control. Sails and parts of the hull, keel and skeg are controlled as to unit weight. Keel, hull and complete boat must meet minimum total weight standards, rigged masts must have a minimum "tip weight" (Spec. 5, 10, 13). Weight of the complete boat and mast tip weight are regularly checked at championship and other series. Yachts are weighed for certification in accordance with Spec. 13.3. 

The most desirable scales for these uses are the electronic "load cell" type which give accurate readings with excellent replicability. Various spring and lever types are also used. While scales should be calibrated with test weights to ensure accuracy, the most important characteristic for fairness in regatta weighing is replicability of readings. This should be checked by weighing the same boat, or mast tip, several times before, and, if possible, during the measurement procedure. The scales should give very nearly the same reading at each re-weighing. if differences are noted, the scales should be repaired or replaced. If corrector weights are necessary due to non-compliance with specified minima, the measurer must ensure that these are installed properly and permanently, and weight seals per Spec. 13.3 are in place. 

CERTIFICATE The Measurement Certificate is as much an essential part of a Star as a mast or sails (Spec. 1). Since the Certificate is the boat's proof of eligibility for competition at any level, it must always be current as to ownership information, and be kept readily available. Original copies of the Measurement Certificate are maintained, and duplicates are available for $10 USD upon application to ISCYRA. 

EXPERIMENTS, PECULIARITIES, AND DISCREPANCIES Technical improvement in the Star have been made during every period of its long history. Most, if not all, are the result of thoughtful experiments by owners seeking to make their boats safer, stronger, and above all, faster. Often such experiments take place in the area of control systems or rigging not limited by the Specifications, in which case measurement procedures are not involved. On the other hand, modifications to areas which are controlled require re-measurement and re-certification before the boat is eligible to compete again at any level. The assistance of the TAB, the Chief Measurer(s) and the Certification Measurer(s) is available to owners contemplating such modifications, and should always be sought to ensure continued eligibility. 

Some modifications or construction errors may be termed peculiarities in a boat. Spec. 1 and 14 make it clear that such deviations from the standard for a Star are not permitted. Measurers, as well as owners, should be alert for any peculiarity in a boat which might not comply with the intent of the Specifications, and seek the assistance of the TAB, the Chief Measurer(s) and the Certification Measurer(s) in determining whether this is the case. 

Discrepancies are actual instances of noncompliance with the Plans and Specifications. No boat having a discrepancy is eligible for competition as a Star at any level (Spec 1). Discrepancies should be corrected immediately to avoid any possibility of an ineligible boat being sold as a Star or entered in competition. 

In any series the TAB, the Certified Measurers and the Event Measurers are requested to pay attention to possible discrepancies and, in case of evidence, to arrange for adequate correction. In any series, the TAB, the Certified Measurer and the Event Measurer are responsible for the total observance of what is stated in the previous paragraph. 

DEFINITIONS Certain terms related to measuring the Star Class Yacht are defined below for assistance in understanding measurement principles: 

BASE LINE. A line in the Center Plane having a perpendicular distance from the hull bottom at Station 10 of 390 and at Station 1 of 486. Hull Stations are located on the Base Line by measuring forward from the intersection with a line perpendicular to it which passes through Point "T". 

BASE PLANE. A plane perpendicular to the Center Plane, and containing the Base Line. 

CENTER PLANE. A plane containing the centerlines of the deck and bottom, the axis of the mast, the center plane of the keel fin, etc. 

CHINE POINT. Any point on the curved line defined by the intersection of the extended surface of the side and the extended surface of the bottom. "Chine Heights" are measured from the Base Plane to specified Chine Points; "Chine Half-Breadths" are measured from the Center Plane to specified Chine Points. 

JIBSTAY INTERSECTION. The intersection of the line of action of the jibstay in sailing position with the forward surface of the mast. 

POINT "B". See Spec. 2. The height of the deck edge is the height of the Sheer Points, and this may be found by supporting a straightedge on the deck at the proper distance from Point "T", measuring form it vertically to the mast step, and subtracting the offset of the straightedge above the Sheer Points. 

POINT "T". See Spec. 2. 

PROFILE. The shape of a part of the boat, such as rudder or keel, as projected perpendicular to the Center Plane. 

SHEER POINT. Any point on the curved line defined by the intersection of the extended surface of the side with the extended surface of the deck. "Side Heights" are measured from the Base Plane to specified Sheer Points; Deck Half-Breadths" are measured from the Center Plane to specified Sheer Points. 

TRUE BOTTOM. The actual surface of the hull bottom, or the extended continuation of the arc of the bottom through the keel flange or skeg. "Keel Heights" are taken at specified points on the intersection of the True Bottom with the Center Plane.

Rules of the ISCYRA Part 2 Championship Rules


Rules Governing Star Class Sanctioned Events and Fleet Qualifications

21. Eligible Boats

21.1. A boat is eligible and considered to be in the Star Class only if it has been properly registered, conforms to measurement rules and is owned by a qualified active or life member recorded at the time as in good standing with the ISCYRA. An ineligible boat must be barred from all Star races, and cannot be reinstated until all requirements of the ISCYRA have been fulfilled.

21.2. Any Star sailing with a number not yet issued (7.3 and 15.1) must be disqualified from all races in which such a number was displayed.

21.3. A boat cannot be registered in more than one fleet at a time.

22. Observance of the Rules of the ISCYRA

The enforcement of the Rules of the ISCYRA is essential to the protection of all Star owners. Members are required to report to the ISCYRA any race held for the Star Class as such, wherein the Rules of the ISCYRA are not respected and enforced by the organization conducting it, or where entries of ineligible boats are knowingly accepted. A member who makes himself party to such practices, by knowingly and after due warning entering such an outlawed event, shall himself be subject to suspension. A Continental Committee may outlaw any event for cause.

23. Championship Events

23.1. The purpose of the Championship shall be to determine annually the appropriate champions by competition among eligible boats.

23.2. All series for major Star championships territorially greater than one fleet, and events for perpetual, semi-perpetual or open trophies, may be sanctioned by the appropriate Continental Committee. Honor insignia and Award (23.5.9.) cannot be awarded unless a sanction has been granted.

23.3. A sanction granted to an event for at least two consecutive years shall become automatic and need not be applied for again, even though the event is held in different localities, unless the event has lapsed for more than two years. The Continental Committee may, however, at any time cancel or withdraw a sanction if it deems such action advisable.

23.4. Application for sanction should be filed with the Central Office on a form obtainable from that office. The Continental Committee will then act on the application (14.3.)

23.5. Sanctioned Events and Awards. Except Gold and Silver Events, all other Events can be sailed as “Combined Events” with separate results.

23.5.1. Gold. World Championship. Open to all Members of all Fleets and to Isolated Members. Entries per STCR 29.1 GOLD awards. The Olympics is also considered a Gold event. (See ASSOCIATION INSIGNIA AND AWARDS)

23.5.3. Blue. District Championship. Open to all Members of all Fleets and to Isolated Members. Entries per STCR 29.2 BLUE awards. To allow all members to participate in another District Championship, it can be sailed as an “Open District Championship.” Honor Awards for the Event and qualifications via the Event are only granted to the winners which are either Members of the organizing District or participating as Isolated Members.

23.5.4. Green. District Championship restricted to Novices (STCR 23.7.1 and 23.7.2). Open to all Novices of a District. GREEN awards.

23.5.5. J. Junior Championships in which boats may be skippered by other than their skipper-owner may be held, as sanctioned, at any of the above competitive levels. A World Junior Championship would be designated as Gold J, Continental as Silver J, etc. Entries in accordance with above rules of each classification. Awards are stars only, as above, but with a large J of contrasting color inserted in the star. No chevrons or bars awarded.

23.5.6. Except for the Olympics or World Sailing-sponsored World Championships or other World Sailing-sponsored events (e.g. World Cup), the above events are under the auspices of the ISCYRA. For Gold and Silver events, the Organizing Authority will be the ISCYRA in conjunction with the host club. For Blue and Green events, the Organizing Authority will be the District Committee and/or local fleet in conjunction with the host club. Entries are selected by qualification series. No other races to be scheduled in the vicinity and courses must be adequately patrolled. Except as Combined Events are allowed by STCR 23.5, no other races may be scheduled in the vicinity, and courses must be adequately patrolled.

23.5.7. Red. An established event of inter-fleet character featuring the Star Class. Open to all fleets, entries unlimited. To winner: THREE RED chevrons.

23.5.8. Fleet Qualifications. Open to all skipper-owners (or part owners), registered before the first race, who are members of the fleet. To winner: ONE RED chevron.

23.5.9. Honor Awards. Honor awards are displayed on main sails. Awards rank in the following order: gold, silver, blue, green and red. For example, one gold chevron outranks a silver star. Only the highest award ever won by any one skipper (either as skipper or crew) shall be displayed or kept on record, except that chevrons of higher rank may be used with a championship star of lesser rank. For example, a skipper entitled to a blue star may use his gold chevrons beneath it. The winner of two championship stars of the same color inscribes both dates in the star.

Awards are made to the skipper (Star, Olympian or Star and chevrons) and crew (Olympian with bars or Star with Bars), not to the boat; if the boat is sold, awards are retained by the skipper for use on any other Star boat he may own while a member of the ISCYRA.

If a crew acts as a skipper he shows his highest award ever won either as skipper or crew.
Ranking of the Honor Awards is: 1.) highest colour, 2.) highest place, 3.) highest won as a skipper before Honor Award won as a crew.

23.6. Special Events.

Events not specified above, but under ISCYRA jurisdiction, require no sanction and rate no honor awards. Intercollegiate, Junior, Ladies’ or other races in which Stars are sailed by other than their skipper-owners (unless specified above), are not under ISCYRA jurisdiction in any form.

23.7. Definitions.

23.7.1. A Novice Skipper is one who has never as a skipper won any series honor that is higher than a Green event honor, or as a skipper won a Green event.

23.7.2. A Novice Crew is one who has never as a skipper or crew won a Gold or Silver event.

23.7.3. A Junior is a person who will not have reached his or her 25th birthday before the first race of the event.

24. Perpetual Trophies

24.1. There shall be awarded to the winner of the series such perpetual trophy or trophies as have been donated or deeded for the purpose.

24.2. The trophies shall be held by the winning fleet until the time of the next series, subject to IGC approval and order.

24.3. Title to the trophies shall be and remain in the individuals who are the current members of the IGC, who may impose any conditions necessary for the safe keeping of the trophies.

31.1. Personnel.

31.1.1. The maximum number of persons allowed in each boat shall be two.

31.1.2. Each person on the boat shall be eligible to compete in accordance with RRS Appendix K. Additional eligibility requirements may be imposed by organizing authorities for regattas other than Gold, Silver and Blue events and Fleet Qualifications.

31.1.3. Team Weight. For Gold, Silver, and Blue events, Fleet Qualifications, the Olympic Regatta, all respective Olympic Trial Regattas and all World Sailing Grade One Ranking Regattas, the total team weight is limited according to the following formula:

S=Skipper’s weight, C=Crew’s weight in kilograms: C = ([100 – S] / 1.5) + 100

Weighing before the event is required. Only for Gold events: Weighing during or after the event is optional at the discretion of the organizing authority as posted in the Notice of Race and Sailing Instructions. For all applicable events other than Gold, weighing during or after the event is only allowed pursuant to a properly filed protest.  Teams found to be in violation of the rule shall be subject to disqualification from any race sailed on the day of the violation.

(a) Two approved personal flotation devices (life jackets), which when not worn, must be readily available within 30 cm (1 ft.) of the cockpit coaming.

(b) One paddle or oar.

(c) One line, minimum diameter 8mm, minimum length 20 m.

31.2.3. The use of stays, sheets, or lines other than those specifically described in this section to support the body of the skipper or crew is prohibited. During the normal act of tacking or jibing both feet of the crew and skipper must remain on or inside the deck edge when looking in profile. No hiking aids or aids to support the skipper or crew outboard are permitted except:

(a) For skipper and crew, footstraps are permitted, of material no more elastic than nylon webbing, securely fastened within the cockpit. These may be adjustable but shall not reach beyond the sheerline (outboard edge of the deck) when fully extended. All footstraps shall be designed so as to come completely off the feet in the normal act of tacking or jibing. The use of hobbles or an individually closed strap for each foot is specifically prohibited. Doubled foot straps, if used, must have sufficient clearance between them so that the user may easily step out of the straps without the use of hands or extraordinary movement of the feet.

(b) For the crew only, a hiking vest that is securely attached within the cockpit or to the deck is permitted. The vest must be attached to the hull by means of a quick release device approved by the Technical Committee. The Technical Committee has approved only the following three attachment devices:

(1) The Ball Lock device consists of a wire attached to the hiking vest at one end with one or more swaged balls on the pennant. The lock (keyhole type) is mounted on the deck. The ball on the wire pennant fits into the lock on the deck while hiking; however, the ball must release from the lock while in the act of tacking.

(2) The Hiking Tang device consists of a rope or wire attached to the hiking vest at one end with a bent right angle tang at the other end. The bent tang may be hooked over the backstay track or into a flat slotted plate on the deck; however, the tang must release from the plate while in the act of tacking.

(3) The Rope in Cleat device consists of an open-ended rope of sufficient tensile strength, which attaches to a jam-cleat mounted on the deck; however, the rope must release from the cleat while in the act of tacking.

Vests must weigh no more than 2.5 kg. The hiking vest shall not be used without the crew’s feet being in the approved footstraps, and shall not be used in any manner to enable the crew to adopt a hiking position different from what would be possible in the absence of the vest.

Commodore For skipper and crew, hand holds mounted on the deck which do not measure more than 50 mm above the deck and are mounted aft of the forward end of the mast opening are permitted.

(d) For skipper and crew, padded trousers or shorts that have sewn-in battens on the backs of the upper legs from above the knee to below the seat to assist in supporting outboard weight when hiking.

31.2.4. The jib may be winged by means of a whisker pole the inboard end of which, when in use, shall rest against the mast.

31.2.5. No sails other than the approved jib and mainsail can be used, and only one of each of these, on the proper hoist, can be above deck at the same time. A race committee shall not allow the use of a sail bearing an incorrect number unless all contestants are advised of the change before the start of the race.

A skipper shall not use or measure in more than two mainsails and two jibs in any series of races including qualifications.

31.2.6. Electronic devices which provide direction information and timers are allowed. VHF radios are allowed.  A competitor may carry a VHF radio for safety purposes and race committee communication.  Use of the VHF radio is not permitted while racing except for emergencies. This restriction may be modified to allow communication from the Race Committee to competitors on a predetermined channel if so stated in both the Notice of Race and the Sailing Instructions and if not prohibited by law.

32. Measuring, Weighing and Sail Controls

32.1. At Gold and Silver Championship events, measurement is required as determined by the Technical Advisory Board. Measurement may include boat and mast-tip weighing, measuring of sails and spars, checking required equipment, and such measurement of hull, keel, skeg and rudder as the Technical Advisory Board shall find necessary. At Blue and lower events, if required by the event authorities, measurement may include such checks and measurements required for higher events as these authorities find necessary.

32.2. When measurement is required, a measurement period to close not later than the start of the first race shall be scheduled and announced, and a regatta measurer with power of approval shall be appointed by the appropriate authority (e.g. The ISCYRA at Gold Events, the District at Blue Events). Except as provided by special rules or by action of the event authorities, no item may be submitted for approval after the close of the measurement period.

32.3. This section applies when measurement includes weighing to verify compliance with Specs. 13. A Certified Measurer authorized to weigh and seal boats as provided in Specs. 13 shall be present. Additional material shall be added to an underweight boat to the extent necessary to meet the minimum weight. Existing additional material may be removed to the extent a boat exceeds the minimum weight. If additional material is added or removed, the additional material thereafter remaining shall be sealed as provided in Specs. 13, and a new plaque affixed to the boat stating the amount of additional material carried. Additional material may be added or removed in accordance with this section at any time during the prescribed measurement period for the event.

32.4. Sails approved for entry shall be indelibly and distinctively marked and only sails so marked may be used. No approved sails may be altered during the event. Repairs are permitted, subject to any special rules regarding permission and reapproval, provided no alterations are made. Approved sails may be used only on the boat for which they were submitted. To control the number of sails used, sails may be marked without measuring, in which case such marking does not constitute any finding of compliance with the Specifications.

32.5. At Blue and lower events, if weight control consists of inspection of weight seals and plaques, such inspection does not constitute any finding of compliance with minimum weight requirement.

32.6. When measurement is required, approval is required for eligibility. Nothing in this Rule, nor any action by the event measurement authorities, shall be taken to reduce or limit the provisions of the STCR regarding eligibility.

33. Measurement Certificates

33.1. No boat shall be eligible to enter any race for the Star Class until it has been granted a measurement certificate.

33.2. Qualified certified measurers are appointed by the chairman of the Technical Advisory Board. Their authority is restricted to the taking of actual measurements and filing a report thereof. No certified measurer shall measure his own boat except under supervision of a disinterested person appointed by the Technical Advisory Board. Measurers are entitled to a fee approved by the IGC. The owner of a boat being measured shall pay the measurer’s fee whether or not a certificate is granted.

33.3. The ISCYRA’s measurement certificates shall be binding upon all organizations conducting races for the Star Class. A boat holding a certificate shall not be subject to remeasurement or protest on measurements unless reasonable grounds can be shown to suspect subsequent alterations or previous mismeasurement. Notwithstanding the foregoing, a boat is always subject to remeasurement by order of the IGC, CMC, IJ, the TAB, or a Continental Measurer (see STCR 15.2.1).

33.4. A protest of the measurements of a certified boat, except as to matters covered by Rule 8.9.3., must be accompanied by a deposit of US $50, which is returnable only if the protest be sustained.

Rules of the ISCYRA Part 1

ISCYRA Rules Preamble

Rules of the ISCYRA (updated January 2017) Summary

The Star is a two person one-design sailboat and was designed by William Gardner/Francis Sweisguth in 1910/1911. 

In its old history the International Star Class Yacht Racing Association (ISCYRA), founded in 1922 by George A. Corry, has not only maintained the rules, but has constantly advanced the technical development of the boat and sailing in general. The Star founded the first Sailing World Championship ever in 1923. Since 1932 the Star has become the oldest Olympic class and is the king discipline of keelboat sailing. In the decades until now the Star has further developed to a high tech boat without losing any of its charm and elegance.

About the Star

The Star is one of the most prolific keelboats in the world for a reason: it is an incredible boat to sail. Designed in 1911 by Francis Sweisguth, it has proven to be a classic in every sense. It is the oldest Olympic class, having first been used in competition in 1932, and still at the heart of that competition today. Supported by a worldwide association the Star as a class is one of the best organized in sailing, with over 7,500 yachts built over its 80 year history, and 2000-plus actively racing today.

The Star has evolved into the consummate craft for all ranges of competition and performance sailing: its equipment and rig is simple enough for the novice, yet versatile enough for those on the forefront of sailing. It's large, powerful sailplan, combined with a sleek hull and light weight, propel the boat in the faintest of airs, while the flexible spar can be tuned to "de-power" when the breeze kicks up. The large main is infinitely adjustable, allowing the sailor to completely control the driving surface of the sail. Boats today are generally constructed of fiberglass, with positive flotation and an integrated keel. The design, sails, and equipment of the Star are governed by stringent class rules, created to improve competition on the basis of skill and control cost . This has also served to help the longevity of the design, keeping older boats competitive through careful evolution.

Stars are generally "dry-sailed", that is, stored on their trailers when not in use, and with a total weight around 1500 lbs, can easily be towed from place to place.

Many of the world's top sailors past and present have been involved in the Star Class. It's list of former World Champions reads like Who's Who of yachting: other top sailors such as Colin Beashel, John Kostecki, Mats Johansson, Hans Vogt, Benny Anderson, Rod Davis and Mark Reynolds are also involved in the Star class. But the class is made up of a variety of sailors of all ages and skill levels. One race on a Star has hooked some sailors for life: they'll tell you: It's a thrill.

Star: Art and Machine

The Star has practiced a philosophy of design evolution over its 80 year lifetime. Always staying at the forefront of sailing technology, the Star maintains a conservative balance aimed at keeping the level of competition high, holding costs in check and preserving the initial spirit of this great yacht. The priorities of safety and practicality have ruled most of the changes made over the years. This control over development of the class has kept boats that would have been retired at their age in other classes racing well into their golden years. Some of the features that can be found on today's Starboat are:

Adjustable Jib Leads
The four-way action of the deck-mounted jib leads allow you to carve the shape of the sail, keeping a good shape to match changing conditions.

Hiking Vest
A simple harness allows the crew to get his or her weight out of the boat more efficiently. Made legal by class rules in 1981, the vest must be equipped with a quick-release to ensure safe exit in an emergency. The vest eliminates alot of the exertion and gymnastics traditionally associated with extended periods of hiking.

Suction Bailers
Developed by Star sailor Duarte Bello, sailors quickly discovered that several strategically placed bailers can quickly and safely drain any excess water in the cockpit Most Stars generally have 4, two in the center of the cockpit, and two located near the chines.

Circular Boom Vang
Also developed by Duarte Bello for Stars, this innovation reached popularity in the 1960's, having proven to be a safe and efficient way to control the high loads of the long boom. This development later spread to other classes, among the 12-meters of America's Cup fame.

Whisker Pole
The simple sailplan utilizes a whisker pole to sail wing-on-wing off the wind, thus making the most of the generous sail area.

Class Sail Measurement
The ISCYRA measures every sail to ensure fair competition: the rules do not allow the exotic materials that drive up cost and cut the lifetime of other racing sails.
