RE: Relocating the Tender
Toss the present dinghy. Measure the full width of the transom, and the full beam of the boat. Go to the dinghy store and let your imagination run wild. You now have an opportunity to put on the largest dinghy your transom can accommodate. It should measure somewhere between the full length of the transom and the full beam of the boat.
Then go to the davit store. There are several different kinds, that mount to the transom just above the swim grid, that will pivot from that point, so as to carry the dinghy well outboard of the aft edge of the swim step when lowering or retrieving. You can get them with an electric winch, hidden in the cross member, or use a manual winch mounted on the rail. Or you can get a pair of davits that just lift from the top of the rail, independent of each other.
Then you will clear your deck, happy up the first mate, who will love the freedom your new 12ft dinghy with a 40hp engine gives her, and make all of your cruising buddies jealous.
