Folding Ladder stores in lifeline gate:
http://bosunsupplies.com/products2.cfm? ... =TOPS-AmidHere is the one I thought would work best for us, but it is a little pricey and when I contacted them a two years ago they were getting ready to work with a new fabricator and were not taking orders temporarily. There is another similar model out there but this is the original as near as I can tell. Our stern ladder is adequate, but could use at least one more step for boarding. I don't mind climbing over the rail, but getting a knee up on the bottom rung is no fun.
Ciao for now ....
