Sy can be rough around the edges but he's a good guy.
I think Full Throttle is a good product but it's like every insurance policy and/or carrier out there. Not ever product is going to be good for everyone or every boat.
So, make sure the product fits you and your boat before getting it. That would be my recommendation. There are several options out there for boat insruance. Check them all out and pick one that suits you.
