Yes I agree with a couple of recent comments.
The ability to be able to get aboard when conditions are not favourable or the person is in difficulty should be the bottom line.
Ladders need the bottom step at a depth
where the person can easily get a foothold and lift
I believe that aesthetics should come last. The setup must be strong, easy to deploy, not collapse or be affected by the conditions and allow a wet heavy person possibly clothed to at least have a chance of climbing unaided aboard.
It a long way up from the water side!
