their rates are very good, until you need to make a claim...then you find out what you think you paid for and what THEY think you paid for - are no where close.
Their experience in boats is quite limited, as they treat them like a car. Similarly their motorcycle policies are based on a "book" not actual motorcycles. For example they have three classes of bikes, going back to 1997...if your bike is involved in an accident, THEY force fit it into one of these classes and years whether it is or isn't.
And god forbid you use the "insured" in a state other than the one it is insured in..then they have to have an appeal to see "whose" state laws prevail, which takes a few weeks, while the "insured" racks up daily charges sitting at the transient dock.
They also will only write ONE check, which has the "settled" clause attached. So you have to pay all the up front charges, and then hope they agree to pay them when the job is completed, because by accepting the check you just signed away any further help from them. In two cases that settlement check included the "salvage title" or constructive loss attachment to your now "repaired" boat...which all but precludes selling or insuring the boat....
You can not treat a boat like a car or motorcycle as far as insurance goes. It simply won't work, but they will take your money and TELL you they are boat insurers.
As cumbersome as a survey is, there is a reason that real boat insurers require them.
YMMV
