I can't believe that is the best that Cecil can come up with!
But speaking of losing your boat, I used to live in Savannah, GA and spent a lot of time on the Big Pond and the intercoastal waterway. My parents came in to visit from Arizona so I figured I would take them beach combing on one of the barrier islands. I was smart enough to time the tides so we didn't get grounded, but I wasn't smart enough to tie a decent knot on the anchor line with that heavy nylon, never-likes-to-knot line. We come back and my boat is now about 150 yards from shore and going out to sea (outgoing tide). Without thinking I run out, and start swimming towards the boat. About halfway out I realize I am no longer the competitive swimmer I was nearly 10 years ago and that distance was never my strong suit. I finally caught up with the boat about 300 yards from shore in the middle of the 80 ft. deep shipping channel. I then learned to tie much better knots.
