When tying down the ends each is tied with a 12 foot length of 1//4 inch
rope. One end is tied to one end of the bumper (actually to the ring under
the bumper they used to tie the car down on the boat from Asia where it
was made) with a bowline knot, passed up and through the ring on the bow
of the boat, then down to the other bumper ring where it is snugged up
with a trucker's hitch.

I found that, unless I actually tied off at the bow ring of the boat, the
boat was free to slide back and forth along the rope. I tie off at the bow
ring with a bowline, run the line down to one end of the bumper, through
that tie down point, across to the other end, then back up to the bow.
