[Tiara Open] Windline boarding ladder

[twilson0929]

I have a 2001 3800 open that has the original 3 step Windline boarding ladder build into the swim platform and covered. Not getting any younger, could use a fourth step. Has anyone replaced this original ladder with a 4 step ladder or made some other modification. Any advice on a specific replacement ladder is helpful. I would need it to fit in the original location on the swim platform. Any advise is appreciated.
