It starts here. New boards. 4’x8’x5” slab of foam has to get cut so I can walk in the garage. On a cold (for LA) winter day when there’s wind and (some) waves but I am tired, I need an excuse to not go out

Be prepared to offer design advice but for now it’s going to have the template of a Quatro and a greatly simplified flat bottom and rails. I’ll call it a “Tres” because it ain’t gonna quite be a Quatro.
