I have a rigid four step ladder. When I want to use it, I snap it into two mounting brackets on deck. I have the brackets just forward of the Genoa track.

I dont go for a swim often so I dont use the ladder much. Although the ladder should be readily accessible, it tends to get buried under alot of crap when stored away.

I always thought that a permanently installed folding ladder off the stern would be a good safety feature. Its not easy to pull yourself back aboard without a ladder if you end up in the drink by yourself.
