Thefts from your boat?

Wondering how many people have had things stolen from their boats when docked or on a buoy? We had a weird incident this summer at Lake Tahoe. We leave our boat on a buoy for a few weeks and ride daily. One morning we shuttle out to the buoy and our nearly new Launch Pad bow sac is gone. Boat full of boards, skis, vests, lines, etc.. and they took one fully loaded 400 pound fat sac. It creeped us all out for a few days. By the way, if anybody out there in WakeWorldland happened to borrow it in a moment of poor judgment, we'd love to have it back, no questions asked.
