Dave, putting a lock box is probably the cheapest and easiest solution, which was my original plan. Just thought I would ask the guru's here for additional suggestions. Not a big fan of lock boxes. Besides, if you ever want to go down a rabit hole, watch
LockPickingLawyer, dude opens lock boxes in under 30 seconds, time after time after time.
I know we are just trying to keep honest people honest anyways here, boats are pretty easy to break into.
