And, once again, I got fooled. I redrew the left sponson bottom and found the runner had no dihedral at all, it's totally flat from side to side. That means I don't have to redraw the right sponson at all, it's already done
Now I get to start working on the forward cross frame the bulnose block, which will be made out of birch,will be epoxied to. This one should really be fun since I have to draw the whole thing from scratch
