Although the term "pleasure boat" is widely used, it is not defined by statute. Under federal law, the term of choice is "recreational vessel" which is defined as a vessel manufactured or operated primarily for pleasure; or leased, rented or chartered to another for the latter’s pleasure. Personal water craft (like a Jet Ski) are considered a vessel. However, under various state law definitions, a pleasure vessel or boat is generally defined as any vessel which is not engaged in commercial activities.
