I think the ladder is a good idea. I am 67 (175lbs) and practiced righting the boat during bathtub calm conditions. The issue is climbing onto the bottom hull. You can't because the deck is where your head needs to be when hoisting yourself out of the water. I found it necessary to climb vertically, like the old rope in gym class, until I could can stand on the bottom hull. I got it done rather easily once I was up there.... but in a blow?
Anyone that has tried a rope ladder? ...or any other idea, I'd be glad to hear it.
