A measured yacht shall also receive a gold seal of the Association bearing the yacht’s number and the word “Measured.” Any yacht which possesses an International Measurement Certificate is presumed to conform to the specifications of the Class regardless of the transfer of ownership unless or until the contrary is established by the following protest procedure:

o a. A protest of the questioned item shall be filed with the Fleet Measurement Committee or Race Committee having jurisdiction. Such protest may be filed at any time but preferably before the commencement of racing.

Where no such rules are specified. the rules of the applicable national and yacht racing body shall govern. The race series to determine – any – champion of the class shall be governed by the racing rules of the International Yacht Racing Union. Except as otherwise provided in the written race instructions. Thunderbird yachts racing in class will conform to the requirements of the Class Constitution and Class Specifications.

8.3 World, National, Regional and Fleet Championships International, National and Regional Championships shall be open only to the Thunderbird yachts and members conforming to the Constitution and the Class Specifications. Regulations regarding Fleet Championships shall be determined by the Fleet. All of the foregoing championship series shall be sailed in accordance with the instructions set forth in Section 8 2 above to the extent practical. Immunity from protest on conditional waivers shall be determined by the sponsoring authority. International, National and Regional Championships require the written sanction of the International Board of Governors.

8.4Sail regulations . No more than one main, one jib, one genoa, and one spinnaker may be acquired every other calendar year, regardless of ownership, except that one additional sail of each type may acquired once during an ownership of a yacht. A new sail which is given to the owner, free of charge as a replacement for a defective sail, is not considered to have been acquired provided that the defective sail is not used thereafter. Sails which have been lost or destroyed accidentally may be replaced outside this quota. An unlimited number of used sails may be acquired provided that they have a minimum of two seasons of use at the time of acquisition as determined by the fleet sail measurer. No more than 2 (two) main sails, spinnakers, working jibs, and 3 (three) genoas may be carried on board during a race. Sails may not be burrowed except in Championship events where the number of participants per Fleet is limited. In this case, sail numbers must represent either the skipper’s yacht number or the yacht number on which they are being used. Reefing shall not be used to effect an undersized headsail. Only those sails illustrated on the plan may be used in this specified position to a maximum of three sails being used at once. Putting sail(s) into or taking sail(s) out of the anchor well is not permitted.

8.5 Crew Regulations. In all races for International, National and Regional Championships, crew (including skipper) shall be all Corinthians and total three or four, all Corinthians and the skipper must be a Voting member of the International Association. In other races, the number of crew and the status (Voting or Active) of the skipper with the Association shall be governed by the local rules.

8.6 Measurement Policy. A carefully constructed yacht should have no trouble coming within the measurement tolerances prescribed in the Class Specifications. This is demonstrated by the fact that many certificates have been approved with no discrepancies


whatsoever. On the other hand, the only purpose of the measurement program is to insure that one yacht does not have an unfair advantage over another by virtue of some discrepancy of design (subject always, to the principal that all Thunderbird yachts should look essentially alike). However, it is always possible that an apparently innocuous discrepancy may later be discovered to confer an advantage. Accordingly, where a yacht has one or more measurements which are not within the official tolerance and it appears, either from the experience of the International Association or on representations of the local Fleet, that the discrepancies do not give the particular yacht an advantage in class competition. the following policy will be followed by the measuring authorities:

o a. The official tolerances will be adhered to in the interest of avoiding seemingly innocuous discrepancies or variations which my later turn out to be advantageous.

o b. Upon request from the Fleet concerned, yachts which have apparently innocuous discrepancies in their measurement certificates, will be approved but the discrepancies will be noted by the term “conditional waiver.”

o c. The yacht holding the conditional waiver will be subject to protest on the noted item(s) except in races which the sponsoring authorities, or all participating Fleets, have granted immunity from protest on said item(s).

o d. The conditional waiver will be limited to innocuous discrepancies and in deciding what is and what is not an innocuous discrepancy. the International Measurement Committee will be guided by (1) their own experience and (2) recommendations from the local Fleet that the item is to be given a conditional waiver.

o e. Each local Fleet is required to make a record of the conditional waivers outstanding in the Fleet which shall be available to all interested members.

o f. It will be the po1icy of the International Measurement Committee not to grant a conditional waiver in a situation where it is felt that the discrepancy could be corrected without undue expense or inconvenience to the yacht owner Therefore Fleets should refrain from requesting such waivers unless they feel that it is the only equitable thing to do.


9.0 The international shall not be liable for any debts contracted by any of its members, Officers of Fleets except for expenditures authorized by the Board of Governors.

This Constitution and these specifications are effective as of January. 1994. All previous rules and rulings are superseded.
