A step up on the Ladder front

I decided that the plastimo standard chandlers ladder that was inherited with the yacht was bit below Rosie's standards. So a I have refurbished an old mahogany ladder and and with new stainless steel lugs, looks the part. The only trouble is that it can only be mounted on the flattest part of the hull, but that was true of the old one too so I am not sure why I am concerned. The wooden one though fold over so you get three rungs under water which is better for a swimmer (or a man overboard).
