HEHEHEHE, I remember those days when I was one of those gung-ho idiots running a 58' Hatteras YF (with high walkways) and used to ROUTINELY jump 5' from the boat onto the dock without even thinking about it. I don't dare do that these days.
Ah, but now we are older and more wise we can now get the boat 5" from the dock and just pass the line ashore.
The boat was 5" from the dock, I was talking about the height. Jumping down from 5' above the dock........
