When you talk to Willie Boats, they will custom make it (all their boats are "custom"). Ask them for the Sam Windle Rocker. The Forks boats, at least the people I know, have that rocker. My willie has that rocker. Its a little more rocker and the flare is a little larger than a "stock" willie. Get the UMWH bottom. I may drag my boat down just for that bottom.
There process is a proprietary bonding process but I know 2 things:
1. What they described is state of the art. I should know, this is my forte as a researcher in adhesive bonding.
2. The guides I know that have had this done have yet had a failed bottom or bond.
