There are several watercraft coverage limitations in a standard homeowner policy. Liability coverage is generally excluded for most watercraft, in most situations unless the boat is a sailing vessel under 26 ft., an outboard of 25 horsepower or less or inboard or inboard/out drive motors of 50 horsepower or less. Also excluded is any business use. Standard coverage for direct damage to watercraft is usually limited to $1,500, an amount that includes trailers, equipment and outboard engines. Additional coverage can be had by endorsement to a homeowner policy or via a separate boat policy.
