Kevin,
If you put an eye strap on the transom in a hard stop with crew weight over 300lbs. You will rip the eye out of the hull !!!
You can put the attachment line on your harness and hook it to a few loops on the main hook line (attached to the boat). Then you only have one line to worry about and you just need to release one line before you unhook from the trap.
This also helps you from "hopping" in big waves. If you crash the bungee will let you get down to the water.
