USCG Required Safety Gear Checklist by Boat Length

What safety equipment am I legally required to carry for my boat's size before I get boarded?

Federal minimums are tiered by boat length (under 16 ft, 16 to under 26 ft, 26 to under 40 ft, 40 to 65 ft), and the single biggest thing owners miss is that the requirement is not just "having" gear — it must be USCG-approved, the right Coast Guard-stamped marine type, accessible, and unexpired. The core five categories are: wearable life jackets (one per person) plus a throwable on boats 16 ft and over; a marine-rated fire extinguisher; visual distress signals on coastal/Great Lakes waters; a sound-producing device; and proper navigation lights. The fastest way to never fail a boarding is to request a free Vessel Safety Check from the USCG Auxiliary or Power Squadrons — they run the exact same checklist and give you a decal, with no citation if you come up short.

💵 $75-$250 DIY to outfit a typical 16-26 ft boat (life jackets, one marine fire extinguisher, VDS kit, horn/whistle); $150-$400+ if you also replace expired flares and add inflatable PFDs. Marine-shop work on ventilation, flame arrestor, or ignition-protected nav-light wiring typically runs $100-$300+ in labor. The USCG Auxiliary/Power Squadrons Vessel Safety Check is free. ⏱ 1-2 hours to inventory, check dates/approval labels, buy any missing gear, and stow it; about 30-45 minutes for a Vessel Safety Check appointment. ● Use caution

Safety: The gear itself is what keeps you alive, so treat shortfalls seriously, not as paperwork. Most boating fatalities are drownings where the victim was not wearing a life jacket — carrying them is the legal minimum, but wearing them is what saves you. Fire extinguishers and flame arrestors exist because gasoline vapor in an enclosed bilge can explode; always run the blower and sniff the bilge before starting, and use only ignition-protected, marine-rated components in fuel and engine spaces. Carbon monoxide from engines and generators kills silently in cabins and around swim platforms — install a marine CO alarm even though it is not a federal carry requirement. Expired pyrotechnic flares can misfire or burn unpredictably; handle and dispose of them carefully (your local fire department or USCG Auxiliary can advise on disposal) and keep current ones separate.

Common causes

Wrong count or wrong type of life jackets — not one USCG-approved wearable per person, kids without properly sized PFDs, or no Type IV throwable on a boat 16 ft or longer (note: canoes, kayaks, and rowboats are exempt from the throwable rule) (most common)
Quick check:
Expired or non-marine fire extinguisher — household ABC extinguisher instead of a Coast Guard-approved marine B type, gauge in the red, or (under the 2022 rule) a disposable unit more than 12 years past its manufacture date (most common)
Quick check:
Expired, missing, or insufficient visual distress signals — pyrotechnic flares past their 42-month expiration, or none aboard on coastal/Great Lakes/territorial-sea waters (common)
Quick check:
No working sound-producing device (horn/whistle) or no/incorrect navigation lights for night and reduced-visibility operation (common)
Quick check:
Missing situational items the inspector checks on bigger or gas-powered boats — backfire flame arrestor on inboard/sterndrive gas engines, proper engine-space ventilation, oil/MARPOL trash placards (26 ft+), and a compliant marine sanitation device (less common)

How to fix it

Confirm your length class first, because every requirement keys off it: under 16 ft, 16 to under 26 ft, 26 to under 40 ft, and 40 to under 65 ft. Measure straight-line bow to stern. Most small runabouts and center consoles fall in the 16-to-26 tier.
Life jackets: carry one USCG-approved wearable PFD (Type I/II/III or approved inflatable) for every person aboard, correctly sized — children must have child-rated jackets that fit, and many states require kids under a set age to WEAR one underway. On any boat 16 ft and over (except canoes, kayaks, and rowboats), add one USCG-approved Type IV throwable (cushion or ring) kept immediately accessible, not buried in a locker. Check that the approval label/stamp is legible and the device is serviceable (no rot, working straps, inflatables with a charged CO2 cylinder and current arming bobbin).
Fire extinguisher: carry Coast Guard-approved MARINE-rated extinguishers (look for 'Marine Type USCG' and a class B rating), not a hardware-store unit. Under the rules effective 2022, disposable (non-rechargeable) extinguishers are unacceptable 12 years after their date of manufacture stamped on the bottle — replace any older ones. Verify the gauge reads green/charged and the unit is mounted in an accessible bracket. Count by length and whether you have enclosed fuel/engine spaces: roughly one 5-B minimum on boats under 26 ft, two (or one larger) at 26-40 ft, three (or a mix) at 40-65 ft. When in doubt carry an extra.
Visual distress signals (VDS): required on coastal waters, the Great Lakes, territorial seas, and connected waters wide enough. Carry USCG-approved signals valid for day AND night — at minimum three pyrotechnic flares rated for day/night use (note the 42-month expiration date stamped on each; keep current ones even if you keep expired backups), or a non-pyrotechnic combination of an orange distress flag (day) plus an electric SOS distress light (night), which never expire. Boats under 16 ft only need night signals if operating those waters at night.
Sound-producing device: carry an efficient means to make an audible signal — a back-mounted or hand horn, or for small boats a loud whistle. Larger vessels (39.4 ft / 12 m and over) are expected to carry both a whistle and a bell.
Navigation lights: make sure the correct red/green sidelights and white stern/all-round light work and are shown from sunset to sunrise and in reduced visibility. Carry spare bulbs. Use marine-rated, ignition-protected fixtures and ABYC-compliant wiring near fuel and engine spaces — automotive parts that can spark are a fuel-vapor ignition risk.
Engine/fuel-space items: gasoline inboard AND sterndrive (inboard/outboard) engines must have a Coast Guard-approved backfire flame arrestor on the carburetor/throttle body (outboards are exempt), and boats with enclosed gasoline engine or fuel-tank compartments need proper natural or powered ventilation (run the blower at least 4 minutes and sniff the bilge for fuel vapor before starting). These prevent vapor explosions — confirm components are ignition-protected and ducting is intact.
Placards and sanitation (mostly 26 ft+): display the oil-discharge (MARPOL) placard and the trash-disposal placard, and ensure any installed toilet uses a USCG-certified Marine Sanitation Device with the overboard discharge valve secured (locked closed) in no-discharge zones and inland U.S. waters. Keep your current registration/documentation aboard.
Book a free Vessel Safety Check with the USCG Auxiliary or U.S. Power Squadrons. They inspect against this exact federal checklist plus state requirements, hand you a checklist of any gaps, and issue a decal — and they issue no citation, so it is the lowest-risk way to verify before a real boarding.

DIY or call a pro?

Almost entirely DIY — this is an inventory and date-check task, not a repair. Buy approved gear, verify counts/dates/approval labels, and store it accessibly. Get a free USCG Auxiliary or Power Squadrons Vessel Safety Check to confirm. Bring in a marine pro only for the installed-system items: backfire flame arrestor service, engine-space ventilation/blower repair, ignition-protected wiring for nav lights or bilge blower, and Marine Sanitation Device plumbing.
