My homeowner's policy will cover up to $1000 if our boats are stolen off of the car. I checked into a boat rider, but it can only be written on a specific boat, which is useless since we own several. It's also expensive, as the policies are designed for craft which have a substantial liability risk. I checked with the ACA and they don't have anything either.

Surely, there must be some company out there that would be willing to write a fixed value blanket policy, so that we're covered up to a certain amount, whichever boats we happen to be using. Anybody know of one?
