Jeff, I'm sorry but you appear to be the paranoid one here....it becomes more and more apparent as the thread goes on. You must not realize how silly it sounds to try and justify a statement like the one you made. Here off the Oregon coast during crab season (like now) I go sailing in crab pots so thick that it is just about impossible to avoid them. Last weekend I sailed over at least 2 of them. The crab pots here have two floats attached by a
line about 10 long. I sailed between the two on one trap...so the
line would have run under the keel literally scraping the bottom of the boat from stem to stern. No problem.
If I had been in anything with an exposed prop between keel and rudder I would have been in trouble.
Oh yes, and if I had wrapped a
line, my prop is only about 2' below the water
line... not directly under the boat which would necessitate a dive under the boat.
Are you just being obtuse?
