The Swallowtail Society

5'10" winged arc-tail.....ready to surf! (almost.) I had a lot of fun on the 6'1" arc-tail that I made for my friend Sei in Japan, but for my size it could have been a lot shorter and lighter. This one has a tri-plane hull bottom with more pinched rails, and the wing preserves the parallel rail of an arc-tail while reducing tail surface area. The side fins are there to help hold the rail in a bit more, as the smaller hulls are a lot more maneuverable and want to be pushed harder through turns. The board shown here has a 1/2" to 1/16" tapered basswood stringer, 4oz glass, and an 8" Greenough 4A (volan) foiled by Larry Allison of Fibreglas Fin Company. Moonlight Glassing!
