Our stern ladder when lowered has lower step about 18" below the waterline, second step about 3" below waterline, and so on. We have a plumb transom and I don't know the details of a boarding ladder for sugar scoop stern, but of course they have already figured this out by adding grab rails in their boarding ladder arrangements.
Bottom line is that every permanent boarding ladder should have a release mechanism operable from the water. Thanks to this thread, I have been convinced to make this minor change to our ladder.

Thanks for your response (I was not notified of it earlier) but I do not agree that it is "very easy to get to with your feet" when the rung is 18" below water level. Adult body dimensions, even IF you can haul yourself up the ladder by 18", mean that your feet will be flailing around trying to step onto the bottom rung that is hard against you and 3 ft higher than your feet! Because of your knees folding forward - and in the way - you will have to move your body out and away from the ladder to get your feet into position. This requires considerable upper body strength. This can also be painful.
On top of that, if you get your feet on that rung, your leg is completely or nearly completely folded - making it very difficult to extend and stand up, even with great upper body exertion.
And it certainly cannot happen if there is any depletion of strength by exhaustion, or other reduced stamina, and/or in bad conditions. Again I beg people to actually try it out. You will be surprised.
By comparison it is an easy matter stepping onto a rung that is 3 or preferably 4 ft below the waterline.
Your suggestion of having a hanging or trailing line down the transom for tripping a latching mechanism from the water so that the ladder can be deployed for use is certainly right on.
Cheers, RR.
