If I recall correctly.. I believe it was Beasho or fat boy (murray)(maybe monkey (bethwaite)) that designed (never built) a skiff..
That had foils on the sides of the wings.. a windward cantered mast with a genacker.. In theory the boat planed till it lifted on the foils..
In reality it would have been a tri.. with a planing centre hull.. Much like the foiled moths we have here..
Being 30 od feet out on a wing and on foils.. thanks but no thanks..
