The
International Americas Cup Class is a class of
sailing vessels that was developed for the
America's Cup competition. These
yachts, while not identical, are all designed to a particular
formula, so as to make the boats involved in a competition roughly comparable, while still giving individuals the freedom to experiment with the details of their designs. The class was established prior to 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. Previously,
J-class yachts were used.
In addition to the America's Cup, IACC yachts are raced in
other regatta, including the IACC worlds.

RUS-24 and re-registered as RUS-62.
