Hopefully, you are never in any kind of boating accident, whether you have a documented vessel or any other kind. However, in the event that you are, there are certain protocols that you have to follow.   To wit, you have to report to your State reporting authority if on your vessel:   Someone dies. Someone is injured and requires medical treatment beyond what first aid can provide. Any damage to the vessel and other property exceeds $2,000 or more. There is a complete loss of any vessel. Someone disappears from the vessel under circumstances that indicate death or injury.
