The OP is from Ontario
. I don't know if there are Canadian restrictions for what he can remove. We always leave the docklines, fenders, spare parts
for the boat's system, boat hook, fire extinguishers, and make sure we're clear, in writing, about what's excluded. One would probably always take one's own EPIRB
if going to another boat. But I think the OP should check with his own area coast guard, or council, in case there are idiosyncratic exclusions.
We even know a guy who left a nice bottle of wine, some good cheese, and crackers, and a small bowl of fresh fruit for the new owners, like a welcome to the new steward of the boat.
