Thanks Craig_Ritchie for sharing the info with us. I got my home and car insurance under the same policy as this way I felt I got a better deal from State Farm. For liability they offered me an umbrella of 2 mil$, no matter where the claim is from, from the house or from the car.
For the boat they got me in the same package, total replacement of the boat (declared value) and liability. It doesn't matter who's fault it is.
