I've got an "over-the -side" boarding ladder that hasn't been used in years ... if you wanna pay shippin', it's yours ... but to tell you the truth, you'd be better to go ahead and spend that shippin' money toward a swim-platform ... good money spent for LOTS of reasons...here's the one I got YEARS ago...this actually ain't a bad price
