CL built 8 Seamasters as far as I know. 1972 and 1973. I believe mine is the first one of the series as the shipyard project name was Mayflower.
There was one for sale on yacht world in Mazatlan MX for the longest time, but it's sold now. There is one that is in Rode island. There is another one on the east coast, not sure where exactly is being moored. There is one in Alaska in a bad shape I'm told. There is this buitifuly maintained one in Florida that I did not know about till now. And there is mine - The SeaWitch. My boat is getting Awlgripped and it's getting a layer of cloth and west systems under the waterline in Mexico.
I'm missing two...
Looks like a very pretty Awlgrip application. Angle of picture regarding boat bottom has my eye a bit confused. Do you have better (more square to transom) photo of bottom showing prop/keel?
Thanks, Art
