When I was a young man, I worked for the Steamship Authority, which was the quasi state run ferry service to the Islands. My first year down there, I bought a Crosby Striper, a 24' traditional inboard bass boat, made by the Crosby Yacht yard in Osterville. For the seven seasons I worked on the cape, I kept it at Crosby's yard, when I went south to work on ocean going tug boats for the winter. Osterville is one of the most quaint, small villages on the cape, and most often missed by the furious paced tourists today; and that's a good thing.
I have no doubt, a visit would yield you some information.

I swear I can smell that wonderful salt air.
