Tailgate design for a Sportfish boat

I have an idea in my head for a tailgate in the transom of a sportfishing boat. Dive platforms are a nuisance when fishing...so a tailgate design would be nifty.
On my design the bottom will kick-out with the top sliding down a rail. So, with a small step up, Grandma can walk right out the back onto the dock. Not to mention that would be helpful with the dinghy and or whopper catch o' the day.

I did a quick Google search and could find nothing. Has anyone seen such a thing??

Oops...just found one. I guess it's Billy Joel's boat design. Doesn't look that strong...hard to tell. It must be very tough:
