We have a Privilege 43 Cat, and we carry 4 F7 fenders (15x38) 2 are used with a fender board, the others are spares. As you travel south, Bahamas, PR
USVI BVI and down island, most marinas are just pilings, you will not find many floating docks. If you are heading south upsize your fenders...a small price to pay to prevent hull damage in more open harbours and heavy wake areas. And a fender board is a must, we use a 2x8 12 foot long, it may sound big but it has save us from damage several times. (hint) To prvent chafe on fender boards use 3/8 line, drill 2 inch hole in side centered 3 1/2 inch from top with hole saw, then with 1/2 inch bit drill down from top directly above 3 inch hole. Thread 3/8 line thru 1/2 inch hole and put a stopper knot in end...this will now sit in 3 inch hole with no line exposed to chafe. Hint 2...when anchored or moored leave 2 fenders over the side about 6 feet apart and just above water. When a friend or the guy collecting mooring fees stops by it will protect you and give them a spot to tie up, a 20 foot bow rider will not trail as well as your rubber dink, it also makes a good storage spot to get them off deck or out of dink (when stowed most dinghys become a junk drawer for fenders and lines).
