Use the marina address but do not put a slip or marina name. That way you are right on the beam. Since you are in a truck all the time you could use a friend or relatives address for mail. Nothing illegal as you are never there anyway. You stay on your boat when not on the road. state Farm is a lot higher than Allstate, they are the cheapest I have found anywhere as well as the South.

Hello I'm Randy Troutman The issue of live aboard is somewhat easy. Most markets will provide coverage for a live aboard, po box address or not. The issue faced here is the age of the boat and no motors. Most marine markets will not provide coverage for a boat without motors. Also a 30 years old boat is hard to get insurance coverage. Most companies require a survey at age of 10 years. The "don't ask don't tell" policy is not good advise. If you conceal a material fact, asked or not, will lead to undesired results. Lastly and of great importance, The IWSF (International Water Safety Foundation) is a non licensed insurance provider. They are currently being investigated by many state insurance departments. If you are insured by IWSF you should mover your coverage asap.
