I just went through it.
Good luck. I just bought a Legend 35.5 and for an agreed upon hull value of $65,000 I am paying $2200/year through Boat U/S. Best I can tell, if you have a policy already in place they have not tampered with it. I was originally a partner in a 1984 J-35 and we were paying about $800/yr for a racing policy with an agreed upon hull value of $45,000. We started that policy about 5 years ago and to my knowledge that premium has never changed. Then, about a year and a half ago, I bought a Carrera 290, which is a $15,000 fiberglass shell on a trailer. My premium is over $1,000/year and it is not valued anywhere near the J-35. It is stored out of the water, I could trailer the boat inland during a storm to protect it, it has no systems (Hvac, plumbing), a tiny outboard, limited electrical wiring, one though hull, no cushions, and a hand held GPS for electronics - compared to the J-35 which is loaded. One of the most important benefits you get from your insurance policy, and probably even more important than the reimbursement for a loss, is the duty to defend in the event of a liability case. But, if you think about it, the cost to cover us for that risk shouldn't be any different if you own a $20,000 or a $120,000 boat. So I would think that we are all paying around the same amount for that part of the coverage. Where is the additional risk to the insurance company to charge that kind of money? But when I asked them about the logic they couldn't give me a good reason why it was so high. I called everyone else I could think of and no one else would even quote me. So we are just sucking it up. Then when we bought the Hunter about 6 months ago, I got even more aggressive calling for additional quotes. I went to the back of cruising world magazine and other publications and called companies advertising that they cover people sailing offshore, and even they said no way. And it is not even about the money, because as soon as they found out we were in Florida, they wouldn't even quote it. So, again, the only quote we could get was Boat U/S. Bottom line is insurance is the biggest scam around. But to answer your question, call Boat U/S. Unless you are military and can get USAA.
