I remember a time when the last dive of the day was made on the axile of a new Ford station wagon back in 85. It was a nice NEW ramp at the time but the abrupt end into the abyss was a killer. The fact that the car's tires weren't chocked was the killer. The year old fish wagon was toast after the soaking. Very sad. Be careful!
Also due to the configuration and closeness of the wall, I've seen big wakes and swells "bunch up" there, totally swamping the inside of a vehicle while launching a boat.
