HI All,   Im going to need Stairs/Steps to get on our  47 commander from the Dock to Aft deck, FInger piers are too small. I measured water line to deck , Approx 4 1/2 feet,?  Sound about right? and does anyone have one to sell, Or have a lead on where to get a used one?  Im already on the sites looking.. Or  if someone has built them, SPecs?? Thanks Rob
