HOW DO I KNOW IF MY VESSEL MEASURES FIVE NET TONS?

Net tonnage is a measure of a vessel’s volume, which should not be confused with the vessel’s weight, which may also be expressed in tons. While you should be able to access this data in the manufacturer’s information or through a gross tonnage calculator, you can also calculate an estimate yourself. A helpful rule of thumb is that most vessels that measure more than 25 feet in length will measure at least five net tons or more.
