I agree with Orion. My uncle owns a good chunk of undeveloped land on the lake. He allows recreational use of the land to the public. When I and my Dad had shorefront property, we never had a problem with people rafting in front of the property. Most people are very considerate.
I know of someone that owns island property. She gets so irratable if someone is even 200 feet off her property. Yet I see her rafting in West Alton and Braun Bay. Go figure!?!?!?!?!
