After 3 Worrell 1000's, lots of Keel boat racing over the past 20 years (am
I that old??), etc., I've also NEVER seen a bowline undo, unless it was on
very inexpensive nylon rope.  A half-hitch on the loose end prevented that.

Learn it, the reef knot, a clove hitch, and the sheet bed (see
http://131.230.57.1/knots.htm) and you will be set for life.  Make sure you
understand the role of each knot.  A figure 8 is also very handy to know.
