“America’s Cup Yachts – Recent Design Developments”, by Peter van Oossanen, Published in the Proceedings of the “Modern Yacht” Conference, organized by the Royal Institution of Naval Architects, 17-18 September 2003, pp. 135-144 (ID No. 4630b).

This paper provides an overview of the trends in the design of International America’s Cup Class (IACC) yachts as these took place in the period between 1992 and 2003 with respect to the design of the hull and its appendages. The trends that are described are those of the decrease in beam on the waterline, the introduction of the knuckle in the bow profile in an attempt to increase effective waterline length, the disappearance of topsides flare, and the various trends in keel geometry aimed at increasing effective span.
