Contrary to popular belief, there is actually quite a few nuts and bolts that go into a marine insurance policy and these often vary widely between insurance carriers. Some carriers allow tournament use, some forbid it. Some carriers cover indirect losses such as a blown powerhead after your impellor has sucked up weeds and caused the water pump to fail while some don’t. Some carriers also have a clause in their policy that allows them to repair your boat by whatever means is most cost effective to them, which typically means replacement parts from China.
Boat insurance is typically not an area that a majority of insurance agents concentrate their efforts so it’s important to ask questions and make sure your agent can provide these answers to help you understand exactly what your coverages are and how you would be covered in the event a claim were to arise.
