I've got a Boston Whaler Outrage 19, but if I had a bad back and was in the Abacos I would be looking for something like a Twin Vee 22 power catamaran
. Power cats have a great, soft ride with less pounding especially into a head
sea (or over a boat wake!) and there is lots of room for dive equipment
compared to other boats of the same length. Further, they require smaller outboards to plane which means less fuel
and they are very shallow draft
. It's like cutting waves with two knifes instead of one spoon.
I recently saw a used one locally that was in great shape and repowered with Suzukis for about $13k.
In the past I owned a 1996 Glacier Bay 26. It wasn't as pretty or as fast as a Fountain but it made a great diving
machine and the crew didn't feel an inch shorter after a day on the ocean.
