I'm finishing a pirate ship in my front yard (photos will be posted later this week). I've got the mast up, but I want to have a rope ladder extending downward to the ship. Every photo I've seen of sailing ships has these ladders. They are made of 4-6 pieces of rope, extending down to the ship, usually attached to block and tackle, with horizontal pieces of rope that are used as steps. I can just try and tie the horizontal "steps" of rope to the diagonal ones, but I was wondering if there is any one out there that knows how to do this correctly, using sailing knots or something so that the pieces of rope do not move.
