Tanton: Palmquist's 1987 Patent.
Adopted in 1992 on a half size (30') Vendee Globe design. These are fixed wings and probably a little too big. Of course the renderings are recent, the original plans were drawn on mylar.
Palmquist used one hull of a catamaran fitted with the wings to prove his theories with success.
