So I settled on a crossplanked skiff for the family, the one in Gardner's more recent books, the Clamming Skiff. She's a little over 15 feet, has little flare, and a HUGE amount of rocker for carrying big loads without dragging a bunch of water around.
That said, she's got a bottom width of over 4 feet. Kinda pudgy for my needs.
If I pull a little width out of the single mold she's bent around, keeping all other dimensions static (sides remain the same, flare, all angles, etc etc), what changes should I expect? Will my sheer or rocker change shape if I retain the angle of the frame? All I want is a reduction in beam as that's a 3:1 L/B ratio, and for a purely rowed boat, that's a bit beamy.
I know the displacement will drop, but odds are I'm not going to haul 1000lbs of clams anywhere around our inland lake.
