He told me, but it was some time ago. But I'm pretty sure it was not Blue Hills Marine. As I recall it was a yard named for a person and the name was somewhat familiar to me. I'll have to ask him again next time we see them.
PS--- Here is the builder info on my friend's boat. I remembered wrong-- the hull maker was not named for a person. I was probably thinking of the designer.
"My lobster boat was built by Flye Point Marine in Brooklin, Maine in 1990. She was layed up and roughed in at the yard in Maine and shipped to Washington State with engine and transmission installed. She is of a Spencer Lincoln design. She was then completed by a local cabinet maker/boat builder."
