For the last 12 years, after full hull
coverage had a tremendous increase for Florida
boats due to hurricane
losses, I've kept liability only for my 44 year old boat. Of course, the choice of a policy and coverage depends upon individual risk management and the value of your boat.
For most all of the years we've lived aboard since 1972 we have used the service
of BoatUS to find our coverage. Every few years they offer a renewal of our policy through a different provider. Just like my health insurance
that is purchased as a large group policy for a better rate, it may be an advantage to bu your policy through a large group like BoatUS in order to gain a better premium.
