International America's Cup Class
class of racing yacht that was developed for the America's Cup between 1992 and 2007
The International Americas Cup Class is a class of racing yacht that was developed for the America's Cup between 1992 and 2007. These yachts, while not identical, were all designed to the same formula to offer designers the freedom to experiment whilst keeping the boats sufficiently comparable to race in real time. The class was established for the 1992 America's Cup because of perceived shortcomings of the 12-metre class, which had been used in the America's Cup since 1958.
In addition to the America's Cup, IACC yachts raced in other regattas, including the IACC worlds.
IACC Sail numbers
IACC sail numbers were issued according to the date when the ACM measurement committee decided that the hull had reached a certain stage of completion. The number came in two parts: the flag state (represented by a three letter prefix) and the hull number. The country code changed as the hull was transferred between flag state to flag state. Only one boat had a sail number issued twice as in the case of RUS-62 which was a new boat based on the heavily modified hull of RUS-24 and re-registered as RUS-62.
IACC Rule
Version 5.0 of the International America's Cup Class Rule was issued on December 15, 2003. Copyright is held jointly by the Defender Alinghi and the 'Challenger of Record' BMW Oracle Racing.
This brief starts where responsible research should: with the source description of “International America's Cup Class” as class of racing yacht that was developed for the America's Cup between 1992 and 2007. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as class of racing yacht that was developed for the America's Cup between 1992 and 2007. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Oct 7, 2025. The linked authority identifier is Q1109616. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1992, 2007, 1958 and 2003.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
