My boat will be on a boat-lift for much of this summer. In the past, I've had problems with birds (mostly crows) crapping all over everything. What have you found works for keeping crows and other birds away? In my Cabela's catalog, there is a 12v deer and critter deterring device that uses an inaudible noise to irritate the hell out of animals. For $20, has anybody ever tried using one of these against birds? And what was the effect on your (or your neighbor's) dog?? I just had an alarm installed, and my plan as of now is to turn up the warning-stage of the proximity sensor so that birds coming near the boat will get chirped at as they get close. I don't know if it will work, but I'm going to give it a shot.
