REQUIRED EQUIPMENT
For the purpose of equipment requirements, motorboats are divided into four classes, according to length. The length of a boat is the distance from stem to stern measured over the deck, excluding sheer.
CLASSES OF VESSELS

PERSONAL FLOTATION DEVICES (PFD)
Personal Flotation Devices are classified by "Type." The number and "type required on a vessel depends on the length of the vessel and whether the vessel is used for recreational or commercial purposes.

Types of Personal Floatation Devices
A vessel of Classes A and 1 (less than 26 feet) must carry at least one Coast Guard Approved "B-1" type fire extinguisher unless (a) it has an approved built-in fire extinguishing system in the engine compartment, or (b) it is an outboard vessel of open construction and does not carry paying passengers.
For the purpose of determining
if an outboard vessel is of closed construction, it is considered to be of closed
construction if it has one or more of the following features:

Class 2 vessels must carry one type "B-II" or two type "B-1" extinguishers, unless equipped with an approved built-in extinguishing system, in which case one type "B-1" extinguisher will suffice.
Class 3 vessels must carry at least three "B-1" extinguishers or one type "B-1" and one type "B-II" extinguishers. If equipped with an approved built-in extinguishing system, two type "B-1" or one type "B-II" extinguishers will suffice.

Sound-producing devices include horns or whistles and bells. Vessels less than 12 meters (39.4 feet) in length, while not required to have a horn or whistles and bells, shall be provided with some means of making an efficient sound signal.
A vessel that is 12 meters, but less than 20 meters (65.6 feet) must carry a horn or whistle that can be heard for one-half mile. It also must carry a bell that has a diameter of at least 200 mm (7.87 inches) across the mouth. Vessel operators may substitute mechanical or electronic sound signal appliance for required sound producing devices is such appliances have similar sound characteristics, provided that manual sounding of the required signals must be possible.
The carburetors on inboard gasoline engines must be equipped with Coast Guard approved backfire flame arrestors or an arrangement of the carburetor or engine air induction system that will disperse any flames caused by engine backfire. The flames must be dispersed to the atmosphere outside the vessel in such a manner that the flames will not endanger the vessel, persons on board, or nearby vessels and structures All attachments shall be of metallic construction with flame tight connections and firmly secured to withstand vibration, shock, and engine backfire.
Inboard vessels using gasoline or fuel with a flash point of less than 110 degrees Fahrenheit and outboard vessels which have enclosed bilges or fuel tank compartments or other compartments into which explosive or flammable gases may flow and be trapped must have each engine and fuel tank compartment equipped with two or more cowled ventilators arranged and ducted for efficiently evacuating such vapors. The ventilation requirement is in addition to, and not in lieu of, the fire extinguisher requirements.
Vessel engines with open-air exhausts and the capacity to operate at more than 4000 RPM must have effective muffling equipment installed on each exhaust manifold stack. Excepted are licensed commercial fishing boats.
