Tom,
I actually think I found something in my file system that indicates that the ladder is a Windline. That said, all three brands mentioned could be the same ladder under different marketing names. What I also did was order a larger bracket to spread the load. I don't have the boat at home right now (cracked hull) but I think the different bracket had three holes and had a longer footprint. To answer your question, I don't fold the ladder flat. The bottom leg lies against the vertical part of the transom and actually due to the shapes involved, only one leg touches. I attached a one inch square of thin plastic to the contact point in order to prevent a wear spot on the boat. The ladder is approximately at a 60 degree angle from horizontal as viewed from the side. It has never fallen down unintentionally. I will try to get a picture in the next day or so. Send me a private message with your e -mail. I cannot remember how far it is attached from the motor mount but it is attached to the sort of horizontal surface on the starboard side. I have aluminum backing plates on the inside. It has been on for a number of years with no apparent problems so far.
