Do not trust the marina!
I own a Hunter 33 that really did have 2 feet of water in it due to an unfortunate accident by the previous owner. I was an eye witness. The list of things that the insurance company fixed was many pages long and pretty pricey. All the documentation was provided to me by the previous owner, and I still have it today. The interior damage included: engine rebuild, new wiring, breaker panel, and battery charger, new cushions and carpeting, new fridge, and stripping and refinishing the interior woodwork.If you did indeed have 2 feet of water in your boat, contact your insurance company immediately and follow their instructions. There may be damage, such as electrical or engine damage, that may not show up right away. The good news is that you may end up with a like new boat inside. Mine has never given me any trouble, at least that I can blame on the previous owner, ha.
