Whattabouta Carolina Skiff
I have seen those thing run in some skinny water, they have TONS of room, draft shallow, lightweight, and they have some now that are not just flat bottom but a bit of a V in the front. The crabbers love them and they are on them everyday in all types of weather and conditions. Looked at a 21 ft at Blacks in Lafayette while I was looking at chainsaws and its rated for 14 people
Thats a lot of weight it can hold and still drafts rather shallow, and man they got some room
