I have a permanent swim platform/step arrangement that has been installed on my E-29. It was fabricated out of teak for the steps (which fold up for storage) and 1 inch stainless tubing for the handrails. The original pushpit rails were modified to make this all work.
It's very useful for getting in & out of the dinghy, and also handy at the dock, if one backs into the slip.
I'll take a photo or two and email them to you by the end of the weekend.
