This Edson Step with the lines going up to the stanchions even with chafe protection wrecked the Cetaol on the cap rail. Also it was a bit more work to hang it. I admit not much but still. So we had brackets on the side of the boat from the PO and we decided we may-as-well use them.
This step is great for getting on\off the paddle board or for guests with hard bottom dinghy's. Hard bottom dinghy's mess with our stern steps.
