Maybe W.F. is not getting into it, but the ICCT Trustees apparently are. This is from their press release about the ICCT event:

The International Catamaran Challenge Trophy was created by a deed of gift given by Seacliff Yacht Club (Long Island) in 1961, as an international match-racing trophy for catamarans. The ICCT has been contested 22 times since 1961. From the beginning, the press used the nickname the “Little America’s Cup” in reference to the trophy and it continues to be known by that name today. The 2004 ICCT will be raced using the 18HT’s and the boats will be governed by the 18HT development class rules.
