Consider hiding a set of boat keys on the boat somewhere. Use your imagination, I'm not going to tell you where mine are hidden.
Another advantage to this is, if you hire a contractor to work on your boat, you don't have to meet him at the boat, just tell him where they keys are.
I do this, but I put it in one of those realtor mechanical pushbutton combination lock cases. That way, even if someone finds my secret location, there's one more level of effort needed.
