I was involved in this as a business proposition. The wife of the president of Walcon (pontoon builders) spotted our "Ladderelle" (a mix of boarding ladder and passerelle - it didn't sell!) SBS a few years ago and remarked to her husband that it might bit a solution to self rescue in marinas.
We talked to Walcon and they stated they provide pull out loops on the pontoons. You swim to the nearest, grab hold and just haul yourself out. I have a problem with the word just.
We proposed a cheap metal ladder for each pontoon to be sprinkled liberally in each bay. There are problems. They do become fouled. In steel, they also (eventually) rust.
We proposed a ladder that would normally be high above the pontoon and thus, very visible, but would slide down into the water when grabbed enabling the necessary two or three rungs under the surface. Produced in aluminium, it would not rust and, above the water until, use would not become fouled. The structure would always have rails above the pontoon to aid lifting out.
As part of our design process, we surveyed marinas' current provisions and asked for H&S comments. It was a frustrating experience.
Walcon were dismissive and eventually switched to grp ladders. There are still too few and they are too difficult to find. Necessarily they need to be at the root of the fingers otherwise they are obscured by boats.
A very unrewarding experience.
