Parents rented a summer place on CC that came with a beetle cat. They sent me down to Bass River Marine in the outboard for sailing lessons. I was 12, as I recall. This old guy (probably 35 or 40) would take me out sailing, then after lunch (brown bag) he'd put me to work in the boat yard. I still remember helping to put new canvas on the deck of a Wianno Sr. At the end of the summer I was invited to a bettle cat race in Nantucket Sound. Don't worry Mom, I said, I have an older and more experienced crew member to sail with me (he was 14). Mom let me sail the race, and we finished - last (my first DFL) - but it was great.
If I got home early from sailing, I would take out the row boat, catch crabs, then sell them door to door. 25 cents for the hard shells, 50 cents for the soft shells. Don't recall coming home with unsold crabs.
