Boating Basics: Before Going Out

Before going out on the water, take steps to make the outing safe and enjoyable.

Vessel Length Classes

  • 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.

  • PWCs and some other vessels are not required to have a capacity plate. Always follow the recommended capacity in the owner’s manual and on the manufacturer’s warning decal.
