I have not done any research in those aspects of lobster boats. My build is strictly a sentimental project, based on a specific boat that I sometimes went out on with it's owner, Bill West. Bill was a friend of my parents & grandparents, and he gave me the half-hull model that he used as a pattern for the three boats that he built. The Donald David, named for Bill's son, was the third (and last) boat that Bill built. You are right about the multitude of improvements to lobster boats over the years, but those are not for my model of The Donald David.Have you visited any of the boneyards in tge Stueben/Milbridge/Jonesport area? The evolution from all wood framing and construction of 1956 to molded fiberglass of 1996 resulted in changes to the working parts. There were also many differences as you came up coast from the MDI builders ti the builders in the downeast yards.
Was your subject strictly trap hauling or also outfitted for scallop dragging?
Grandmother & Grandfather Haskell had a cottage on Pigeon Hill Rd, not too far from Milbridge. I have been to Eastport a couple times back in the 50's/60's, they had a really great store there with lots antique woodworking tools.
