Boat Insurance recommendations?

[Descant]

I was in the insurance business for 25 years before retiring. To me, that stuff about aftermarket vs OEM is just so much BS. The parts are guaranteed, and if they don't fit, you get a rental car for the time delay. And I'm not buying a new fender for my boat, so I can't figure what aftermarket parts I'd get for a boat. Except for the hull itself, much of the boat is aftermarket anyway.
I have Progressive via USAA. Had a claim a few years ago, the adjuster talked to the marina (MY marina, not one they chose) and wrote a check on the spot. They know it's a short season.
There are likely advantages to keeping as much business as possible with the same firm/agent, like personal items stolen from your boat that may be covered under homeowners, etc.
