Some Watercraft Insurance Coverage's:

Bodily Injury Liability

For injuries that you caused to another person.

Uninsured / Underinsured Boaters

As with Auto insurance, this coverage is there to protect you in the event that you are in an accident with an uninsured boat or a hit-and-run.

Collision & Comprehensive

These are the coverages for your boat.  Collision is coverage for if you collide with another watercraft.  Comprehensive coverage applies if your boat is damaged by something other than collision with another watercraft, for instance, fire, theft, or vandalism.

Personal Property

This coverage is for any personal possessions that you may have on board, but are not essential to boating, such as fishing equipment.
