I bought our 42 with one of these Scanmar ladders already in place. I also have the Edson step that I have had for years and kept ti with me as we moved boats... My preference is the step vs the ladder. The ladder I feel is in the way when folded up and on deck. The step is easy and able to stow when not in use. However, I have had some folks on board that are a bit unsteady in their footing that definitely would be better with the scanmar ladder as it offers a more sure footing, especially in bouncy mooring fields. My 2 cents...
