I needed a better swim ladder but in that we sail in Maine mostly, our swim ladder gets infrequent use. The best ones were high cost for our use, so I decided to build a simple something I could knock down and leave in the lockers for a few days a year.
I sort of ended up with this as a mock up, I thought, but I think it's permanent now. I used a set of old boarding ladder hitches mounted on the hull to affix the new one. I got a lot of laughs on it in the design stage from my family as put it together at home. "Ha ha...dad,...you can't be serious,..."
But I put this on the side of the boat after arriving in Cuttyhunk from Maine a few years ago, and everybody stopped laughing.
For the first time, they had a nice wide foot sized step, well below the water, for an easy use climb. The hand holds take all the work out of easily stepping up. The dinghy fender material attached to the rails just below the carriage bolt head that slide into the old mounts, stabilizes the ladder against the hull.
Your weight pins it plumb and tight to the hull. The problem now, people like to linger and hang out on it so there can be a line to board....
Now the first thing I have to do when the water is warm, is pop the rails into the gains cut in the treads, and tighten the wing nuts(it stows to a small package). Just pine, some hardware, paint.
They don't laugh at my ladder anymore,...
