The op I use (a nice white boat) has a side cutout for retrieving gear. Personally I would never want to try and do a giant stride entry from there. Its bottom is about six inches from the deck, and its bottom is about 1" wide. That bottom is not reinforced with anything so I expect that standing on it could damage it. None the less, you would have to step up six inches (with all your gear) and balance on a 1" wide piece of fiberglass, while ducking so as not to hit your head on the overhead canopy. So I think it would be very unsafe.
Pic? I think I would just giant stride over 6 inches. Or put my fins on in the water.
