Course Outline

Federal law requires all vessels, including PWC, to have a Type B fire extinguisher on board if one or more of the following conditions exist:

  • Any inboard engine
  • Closed compartments where portable fuel tanks may be stored
  • Double bottoms not sealed to the hull or which are not filled completely with flotation material
  • Closed living spaces
  • Closed storage compartments in which flammable or combustible materials may be stored
  • Permanently installed fuel tanks (any tank where the removal of the tank is hampered by the installation of tie-down straps or clamps)

In Massachusetts, all vessels with a motor of any type are required to have a Type B fire extinguisher on board. The only exceptions are:

  • A vessel that is of open construction, is less than 26 feet in length, has an outboard engine, is not carrying passengers for hire, and is not on federally controlled waters.
  • A jetboard or eFoil provided the operator is wearing a PFD.

Approved types of fire extinguishers are identified by the following marking on the label—“Marine Type USCG Approved”—followed by the type and size symbols and the approval number.
