I got what I feel is a fair price in my pocket after paying his commission, the buyer is getting the boat at what they feel is a fair price and he gets his commisson. Seems like a win-win-win to me.
midlife - I meant no disrespect and sorry if it seemed so. It's just that I hate to see money on the table and would have negotiated his fee down to 5% - 7-8% at the most, since you didn't contract his services. He would have co-broked the deal if you hired another broker to list. But hey . . that's just me.
At any rate, you're right about the quick deal, with little effort on anybody's part and Congratulations are definitely in order. best of luck in your new boat search.
