I've had experience with State Farm involving a maritime attourney once before ... but there was a bit of a dispute regarding fault at the time.

What makes me nervous is when you approach a car company looking for insurance and they have no idea, not only what a brand name for a catamaran is, but what a catamaran is in general. State Farm was this way for me (although my agent generally sucks anyway). These people are writing me a policy for something they can't even comprehend? I was pretty impressed when Progressive actually had information about a "Nacra F18" and didn't need to ask me any stupid questions about it. Then, a year later, I get a letter from Progressive thanking me for my continued business and informed me that because I hadn't had a claim in the last year, they reduced my deductable by 25% of the original amount and will continue to do so for the next four years until I'm at zero. I was pretty impressed.
