Boat insurance (or watercraft insurance) policies usually have two standard elements, with two optional extras that are worth considering. One standard feature is insurance coverage for physical damage to the boat, whether that be from a collision, fire, severe weather, theft, or vandalism. The other standard feature in a boat insurance policy is liability, meaning you’re covered for damage you cause to other boats or people, along with the associated legal costs. Look for insurance policies that cover the costs of cleaning up any oil spillages if your boat is severely damaged, as well.
