I know this has been a topic in the past and one that I had to deal with real recently. I purchased a 2002 55' aluminum monohull with a group of 5 other owners. Having multiple owners limits the insurance options. As most of you know, the most common option is a commercial policy through Markel. These policy's are great, but the premiums are fairly high, and the requirements from Markel to obtain issue a policy are cumbersome. I was able to get a policy issued through a State Farm office out of Sandy, UT. If you are having trouble with a policy, let me know and I can put you in touch with the folks here in Utah that were able to get it done.
