Important things to do in the event of a loss

Prevent further damage. If the vessel or other covered property is damaged, you must take all reasonable steps to protect it from further damage.
Notify the police. If your property has been stolen or vandalized, you must immediately notify the police and file a police report.
File a Boating Accident Report. You are required by law to file a Boating Accident Report with your state boating authority if:

The damage by or to your vessel or its equipment exceeds $500 (less in some states), or if there is complete loss of the vessel.
There is personal injury requiring medical treatment beyond first aid.
There is loss of life or disappearance of any person on board a vessel (under circumstances that would indicate death or injury).
