This coverage is also known as wharfkeepers legal liability or landing dock bailee liability insurance. It covers the insured's legal liability for loss or damage to vessels in the insured's care, custody, or control. Coverage is also provided for the insured's legal liability for loss or damage to other property that is caused by vessels in its care, custody, or control. This liability coverage is usually purchased by insureds that have vessels, watercraft, or other equipment moored on their premises. The rating is based on the number of days or hours a vessel is on the insured's premises. Underwriters usually charge a minimum deposit premium against which the rate per vessel day is adjusted. The coverage may be included in the general coverage for a marina operator where a combined policy covers ship repairers' legal liability, wharfingers liability, and liability to vessels stored.
