Anyidea where I could find information on the hull number?
There wasn't any standard numbering system in the US until after this thing was built. It was up to the builder as to how, where and IF the hulls were numbered.
In CT, one HAS to have a hull# in order for a vessel to be registered. If you don't have one, you have to get them to create one and they affix it to the hull.
The hull does look like it COULD be an Alberg design. But it's really hard tell from the angle of the photo. The bowsprit and outboard chainplates make me think that it was orginally sold as a 'kit'. Another photo would help if that's possible. Especially something showing the boat in profile.
