An idea for all, not just for older people:
When moored bows in to a low level catwalk often there is a problem to safely climb up the boat or come back down to the catwalk.
To solve this problem I have mounted a special plate from stainless steel (see drawing) on the pulpit, with a teak plate on it, that will allow a standard bow-ladder to be attached.
When not in use the ladder is stored on deck next to the pulpit, secured by a bicycle type padlock against theft.
