A vessel’s length class dictates the equipment necessary to comply with federal and state laws.
Vessels are divided into length classes:
- Less than 16 feet (Class I)
- 16 feet to less than 26 feet (Class II)
- 26 feet to less than 40 feet (Class III)
- 40 feet to less than 65 feet (Class IV)
Length is measured from the tip of the bow in a straight line to the stern. This does not include outboard motors, brackets, rudders, bow attachments, or swim platforms and ladders that are not a molded part of the hull.
