I'm in MA so insurance is always more expensive. Covers full replacement of the hull for damage, replacement of the engine for damage, uninsured boat hitting me, theft, fire, vandalism, everything that's on it (rods, electronics, etc...). If mine sank to the bottom I'd just call them up and get it replaced. It's pretty much the same as my auto insurance, but the replacement price is the cost of a new one, not a depretiative value like in a car.
