I just bought a 1978 Ebbtide Captiva that I'm restoring. The boarding ladder is basically toast. I'd like to replace it, but I can't for the life of me find a suitable replacement. The ladder was mounted on top of the stern on the port side, with brackets that the ends of the curved poles slid into and were secured with screws. I really want to avoid drilling more holes in the boat if I can, but the main objective is getting a workable ladder. Otherwise, we can't swim and then get back into the boat. Can anyone suggest some solutions to this problem? Thanks in advance.
