Williwaw hydrofoil

Post by Chris Clarke »

The subject of Wiliwaw, the pioneering hydrofoil trimaran, came up during comments on the (very good) zoom meeting on the Americas Cup. One interesting connection is that Tom Speer, an aerodynamicist who has worked on at least one Cup campaign, has done a very comprehensive design study about what a modern-day (well he did the study 20 years ago) Williwaw might look and perform like. All the details can be found at:

It is a fascinating read.

It is also worth pointing out that 'Hydrofoil Voyager: WILLIWAW, From Dream To Reality and Toward the Sailing Yacht of the future' by David Keiper was reprinted a few years ago and is currently available on Amazon UK for less than £10.
