Does anyone here know what kind of boat this is and Manufacturer?
I can tell you that it’s a boat that wasn’t meant to be propelled by a paddle. Did you look for a serial number?
Have looked all over it for numbers, there are none. There are oar locks on it and kind of resembles a large canoe. It is fiberglass though.
Have you got more photos and dimensions? Hard to judge scale, Looks like it could be some kind of wherry or rowing dory that somebody modified for use with an outboard motor by adding the bow deck, clearly home-made windscreen and canopy support. There have been many kits and home build design plans over the years for small open rowing craft of that general shape and people do all sorts of things with them. My friend and former sea kayaking mentor John Jensen in Connecticut on LIS, used to build open water rowing dories that looked similar. They were often used as ship to shore yacht tenders in the coastal area where he lived.
