The second boat builder I worked for - power boats - in the late 70's really didn't need the money it was more that he wanted a boat with his name on the boat. Anyway he left the business when liability insurance got so high, offered it me, I ran the business for him. I almost took the deal but decide on a real job as I was getting married. You always wonder what if …. The mark-up was about 2/3rds back then on the complete boat, plus everything you sold them as an add-on was gravy not counting return shop fees. But like I said he did not want the insurance liabilities he already had his pile of money.
