yes it is high but when you call and talk to Wake Zone they have answers for your questions and examples they have had. When I called other insurance providers they had to ask their supervisors if they could even cover the ski and normally make the comment "people spend that much on jet skies?". So when I have a 25,000 dollar claim I worry that I did not read the small print and they wouldn't cover it.
I just felt more comfortable spending a few hundred more dollars a year knowing that my ski is covered by a boat specific insurance company.
