What additional coverage typically requires a separate policy?

Boatowner's coverage typically requires a separate policy because it addresses the specific risks associated with boating activities, which are not covered under standard homeowners or automobile insurance policies. This type of coverage encompasses liability issues in relation to watercraft, such as injuries to passengers or damage caused by the boat to other boats or property on the water.

In contrast, homeowners coverage often includes personal liability coverage and protection for personal property situated on the premises, while automobile liability coverage is designed specifically for vehicles on the road. Personal property coverage is usually a subset of homeowners insurance, extending protection only for specific items potentially lost or damaged while at home. Therefore, boatowner's coverage stands out as a specialized insurance product that caters to the unique nature of boating risks.
