Airdeck 340 - 2nd keel stiffener?
Found that could feel transition to plane as ripple through hull. Thinking a second stiffener between factory stiffener & transom may help hull shape, improve plane, and reduce stress on seams - same thickness, round edges, coat in varnish...
Anyone ahead of me with this idea? How executed, what was the result?
Running 20hp Merc, no problem planing at 21 mph with full tank and 410 pounds of adults and kids.
