Noting the response from premiermarine it appears they only insure in a handful of States and are a Surplus Lines group and apparently an Agency that insures their stuff through London.
Since London is not interested in any premium less than $1,500.00 per person it is unlikely that they would be competitive. However, that being said, one must recognize that they probably are on our reinsurance currently through our present insurance carrier. But reinsurance is totally different than direct insurance.
I spent many years working with London and Lloyds and I really don't think we want to get involved in an insurance program that generally takes a year to get claims paid. They are extremely slow. By having a domestic company insure us, they pay the claim now and wait to get paid by London, or, deduct the claim from what they owe London.
The program we have now makes a lot more sense.
