Not that the OP is trying to do this, but I don't think you can objectively compare the two hulls. Two markedly different boats designed with different purposes in mind. Seemed like 3:1 was the accepted length to beam ratio in the early 80's, but lobster fishermen wanted to carry more and more traps necessitating a wider boat. Head sea ride not as important as barge-like stability and carrying capacity. This lead to the wider Beal boats.
Duffy 35's are almost legendary on the Cape for their ability to raise, and sneak up on, GBFT. I can think of probably a dozen off the top of my head that were rigged as trolling and/or harpoon boats in the 80's and 90's. But the fishery has changed....15 yrs ago I didn't know one guy who anchored or drifted and chunked, everyone trolled. Everyone had a tower or at least an arch to run the outriggers off of. Now it seems like nobody even puts outriggers on the boats anymore and a boat that has a 2.5:1 length to beam ratio and is built on a skeg is fine.
