Just a thought, security would also be a possible reason. I sometimes don't get out to my boat for months at a time and the other day I went out and someone had stolen the little grill I keep in the transom. Having other people on the boat might have created enough traffic out there that whoever stole it might have had second thoughts about digging through my transom. At any rate, this is something I've been considering for quite a while, just trying to find that right partner to get things going.
