CAPACITY

The capacity of a boat is generally predetermined by the manufacturer. If your boat is exempt from having a capacity plate, such as personal watercraft, you should reference the owners’ manual and state laws. Since 1972, all single-hulled recreational boats less than 20 feet in length have a placard, in sight of the operator, stating the “capacity” of that boat. A capacity plate states the maximum number of people, weight* and horsepower. Operators should never exceed the rated capacity.

If you have a homemade boat, or one that was manufactured prior to 1972, it will not have a boat builder’s capacity plate. In this case, a rule of thumb for determining the number of people is:
Length x Width divided by 15 = approximate number of people (ex. 12’ length x 4’ width = 48 divided by 15 = 3.2). You should round down to just 3 people being allowed on board.

* Average weight of a person is considered to be 150 pounds.
