From what I've been experiencing, it seems as though a sizeable proportion of the boater population ignores them anyway!
I can't begin to count the number of times this season that I've had to come off plane or alter course when I was supposedly the "stand-on" boat to avoid some nimrod who either doesn't know or give a darn about the right of way rules, and I seem to be perennialy zigging and zagging in a futile effort to maintain 150 feet between my boat and these turkeys.
This past weekend took the cake, though. Two total idiots in performance boats used the other boats going through the Eagle Island channel as slalom markers. I don't think that they gave any of the rest of us more than 10 - 15 feet of clearance.
I did make one interesting discovery, though. My new airhorns will cut through the roar of large twin engines to get their attention for my "salute"! Anybody know of a boatyard that will install torpedo tubes?
