4.1 Required Safety Equipment & Carriage Regulations
Key Takeaways
- Carry one wearable USCG-approved PFD per person; boats 16 ft and longer must also carry at least one throwable Type IV.
- Pyrotechnic visual distress signals require a minimum of three for day use and three for night use on coastal waters.
- Fire extinguisher counts follow vessel length: under 26 ft = 1 B-I; 26 to under 40 ft = 2 B-I; 40 to 65 ft = 3 B-I (fewer with an approved fixed system).
- A vessel 12 m or more must carry a whistle; 20 m or more must add a bell; under 12 m needs some efficient sound-signal device.
- Gasoline engines need a backfire flame arrestor, and enclosed gas compartments need ventilation - run the blower four minutes before starting.
Required Safety Equipment and Carriage Regulations
As the operator of an uninspected passenger vessel (UPV) you are legally responsible for carrying a specific list of Coast Guard-approved safety equipment. On the Deck General & Safety module the examiners test the exact counts, types, and length breakpoints - memorize the numbers, not just the concepts. The governing rules for a six-pack boat live in 46 CFR Subchapter C (uninspected vessels) and 33 CFR (equipment and Navigation Rules). A Coast Guard boarding officer can check every item below, and because you carry paying passengers a missing item is both a citation and a real safety gap.
Personal flotation devices (PFDs)
Carry one Coast Guard-approved wearable PFD (Type I, II, III, or V) for every person on board. If your boat is 16 feet or longer, you must also carry at least one throwable Type IV device (ring buoy or buoyant cushion) that is immediately available. Boats under 16 feet, and canoes and kayaks of any length, need the wearable-per-person count but no Type IV. A Type V (special-use or inflatable) counts only if it is worn as marked. PFDs must be the correct size for the wearer, serviceable, and readily accessible - not sealed in the original plastic or buried under gear.
Visual distress signals (VDS)
On coastal waters (the territorial sea, the Great Lakes, and connected waters at least two miles wide) you must carry USCG-approved VDS. Each device is rated for day use, night use, or day/night:
- Pyrotechnic red flares (handheld or aerial) and orange smoke: if you rely on pyrotechnics you must carry at least three for day and three for night. A day/night flare counts for both, so three combination flares satisfy the whole requirement.
- Non-pyrotechnic: an orange distress flag counts for day only; an electric SOS distress light counts for night only.
Boats less than 16 feet need only night signals, and only between sunset and sunrise. Pyrotechnic flares expire 42 months after their manufacture date - check the stamp and replace them.
Sound-producing devices
Under Navigation Rule 33, a vessel 12 meters (about 39.4 ft) or more must be provided with a whistle; a vessel 20 meters or more must add a bell; and 100 m or more adds a gong. A boat under 12 meters is not obliged to carry a whistle and bell but must have some means of making an efficient sound signal - a fixed horn or a portable air horn. You need a sound signal to make the maneuvering and restricted-visibility signals from the Rules of the Road module.
Fire extinguishers
The number of hand-portable extinguishers depends on vessel length and whether an approved fixed system protects the machinery space. The OUPV exam uses the traditional B-I / B-II classification:
| Vessel length | No fixed system | With approved fixed system |
|---|---|---|
| Less than 26 ft | 1 B-I | 0 |
| 26 to less than 40 ft | 2 B-I (or 1 B-II) | 1 B-I |
| 40 to 65 ft | 3 B-I (or 1 B-I + 1 B-II) | 2 B-I (or 1 B-II) |
A B-I unit holds, for example, 4 lb of CO2, 2 lb of dry chemical, or 1.25 gal of foam; a B-II is larger (15 lb CO2, 10 lb dry chemical, or 2.5 gal foam) and substitutes for two B-I units. The class letter B means flammable liquids - the dominant marine fire risk is fuel. Extinguishers must be approved, mounted, and charged (gauge needle in the green).
Ventilation and backfire protection
Gasoline vapor is heavier than air and pools in the bilge, where one spark can cause an explosion - the greatest fire hazard on a gas boat. Two rules address it:
- Backfire flame arrestor: every gasoline inboard or stern-drive engine (outboards are exempt) must carry a Coast Guard-approved flame arrestor on the carburetor to contain a backfire.
- Ventilation: boats with enclosed gasoline engine or fuel-tank compartments must be ventilated. Boats built after August 1, 1980 need a powered blower; older boats need natural (cowl) ventilation. Run the blower at least four minutes and sniff the bilge before starting the engine.
Engine cut-off switch and navigation lights
Two more items round out a lawful boat. Since 2021, federal law requires the operator of a boat less than 26 feet to use an engine cut-off switch (ECOS) link - the lanyard or wireless fob that kills the engine if the operator is thrown from the helm - whenever operating on plane or above displacement speed. It prevents the runaway-circling boat that has killed people thrown overboard. Separately, a vessel operated between sunset and sunrise or in reduced visibility must show the correct navigation lights for its type and length (detailed in the Rules of the Road module); a burned-out light is both a violation and a collision risk, so carry spare bulbs. Neither item is optional on a boat carrying paying passengers.
The pre-departure check
Build a written pre-departure checklist and complete it before every trip: PFDs counted for the actual passenger load, Type IV rigged and ready to throw, flares in date, extinguishers charged and mounted, blower run, horn tested. When an exam question gives a boat length and asks for the required extinguisher or PFD count, work straight from the tables above rather than guessing.
