That's a nice build. Once you start laying the strips on it all makes sense. I would suggest drilling some holes in the ribs and spine so you don't create sealed bulkheads, it's good to have the hollow chambers connected with air holes so you can let it vent properly. Plus if you make holes in the ribs and spine your also removing material which is weight reduction. The strength won't be compromised by holes.
Running 0 degrees toe for the back twins and a 5 degree toe in for the forward. I figured a true old school fish planshape would like free running twins. But the quad option is there too. What do you avid short boarders think of this ?
So basically what I've done is built a close tolerance blank much like a foam blank but it's hollow wood instead, it has just enough wood in the rails to then be sculpted to its final shape with hand sanding and using a belt sander.
So yes the shape you see on the board with the fins is the plan shape. Once that's cut I shape the rail profiles And rocker is already laminated in. 3 inches in the nose with 1.5 in the tail. Rocker apex is fairly far forward id say so the tail is flattish
