If you like that one consider this. Once the boat is truly clear of the harbor on the first day. Toss one of the fenders overboard and have all the males sit down out of the way in the cockpit. Have the combined female resouces on their own motor the boat close enough to the fender for an exhausted swimmer to get to the ladder and get back on board. All the men in silence should time the drill. Then on the first morning time the swim test. As a skipper how long can you tread water in the open sea. How long will it take your given crew to get back to you. We do a fender recovery drill on the first day of every charter. If we have people on the boat who want to learn we will do fender recovery drills each time the boat moves rotating the helm.
