Adam,
Thanks for your observations. We attended the Catboat Assn meeting in Groton CT last month. We have some good leads and the most supported was this may be a Phinney Boat. Phinney had a boatyard in Monument Beach off Buzzards bay in the early 1900s. Unfortunately, we are unable to find any source for factual or even anecdotal information about Phinney boats. We have been in touch with the Maritime Museum on Long Island and they were unable to find anything helpful.
I also appreciate the suggestion the carved # may be an old CC Documentation #. That may be helpful. Do you have any suggestions on how to research the NJ builders?
I will also be posting to see if anyone knows of sources to find about Phinney boats.
Thanks for your observations.
Patty (Tradewinds support team)
