Any suggestions for a fixed mount transom boarding ladder for a 1978 oday20 that is sailed solo? The positive slope of stern makes mounting a telescoping ladder questionable. I'm considering a four step folding ladder (17" folded, 33" deployed, 10.5" W}. No option strikes the balance between: 1) narrow enough that it does not interfere with the rudder Or protrude beyond the outside edge of the stern 2) short enough to not drag in the water while sailing folded Yet long enough to give enough leverage to pull myself out of the water when unfolded. Side mount, temporary mount, or rope ladder is not an option for me. I've reviewed old post and did not see a solution.
