Version 1.0 was a success so V2.0 will be a carbon/kevlar version. Best case scenario is cutting 10 pounds, from 48 to 38. I think 7 or 8 pounds will be more realistic though.
Made a couple very minor changes to the hull. The entry and exit lines were pretty hollow on V1 which made it a little hard to strip; I actually fattened up the first and last forms with a lot of tape to widen them. So this time I widened the water line at the entry enough to keep it a straight line. Had to recut three forms at the bow and stern, the rest I could reuse.
I also took a little material off the bow stem which reduced the waterline length by about an inch. It seems backwards but I'm actually hoping this will loosen the stern a little. I wanted to keep the stern the way it was to aid in tracking across lakes in the wind but I'm hoping with the extra rocker in the bow that, when I want more maneuverability and a lighter stern, I can slide the seat farther forward. The way it was before when I tried to do that the bow would start to pin before the stern loosened up as much as I wanted.
The mold is stripped and I've got it pretty well sanded tonight. Tomorrow I'll probably start adding bondo and sand again. The wood strip mold will be sacrificial. The wood was salvaged from cedar 4x4s I had left over from when I tore down my old house. Full of knots and nail holes but it gave me enough strips to do 90% of the mold. After the composite hull has been laid up I'll take the whole thing off the forms, flip it over, and rip out the wood. This will let me close the stems when I lay the cloth.
