What should be on a boat safety checklist?

01What the law requires you to carry (US federal floor)

US federal law sets a prescriptive equipment minimum under 33 CFR Parts 175 and 183. The core rules, per the USCG's official guide:

• One USCG-approved wearable life jacket per person, readily accessible — not buried in bags or locked compartments (33 CFR 175 Subpart B).
• One throwable (Type IV) on boats 16 ft or longer, immediately available. On shorter boats, a throwable no longer substitutes for a wearable.
• Children under 13 must wear a PFD while underway on federal waters, unless they're below decks or in an enclosed cabin (USCG).
• Fire extinguisher (details below).
• Sound-producing device — a whistle or horn capable of a 4-second blast audible half a mile; boats over 39.4 ft (12 m) also need a bell (33 CFR 83; VSC standard).
• Visual distress signals on coastal waters, the Great Lakes, territorial seas, and connected waters up to where the waterway narrows to less than 2 nm. Minimum: three day signals plus three night signals, or three combined day/night devices. Pyrotechnics must be unexpired — 42 months from date of manufacture — and serviceable. Boats under 16 ft, open sailboats under 26 ft without propulsion machinery, and manually propelled boats need night signals only (USCG; BoatUS Foundation).
• Ventilation and backfire flame control for gasoline inboard boats: boats built after July 31, 1980 need an operable ventilation system with two ducts, and engine compartments with a cranking motor need a power exhaust blower controllable from the instrument panel. One approved backfire flame arrestor per carburetor on all gasoline engines except outboards, marked SAE J-1928 or UL 1111 (33 CFR 175.201, 183.610/.620).

Fire extinguishers — the post-2022 rule

Since April 20, 2022, boats model year 2018 and newer may carry only 5-B or 20-B UL-rated, date-stamped extinguishers; legacy B-I/B-II labels no longer qualify. Boats from model years 1953–2017 may keep serviceable B-I/B-II units, but any date-stamped disposable extinguisher must be no more than 12 years old (USCG, citing 33 CFR 175.320). If you're on an older boat still carrying B-I/B-II gear, that's grandfathered — the 12-year clock still applies to dated bottles.

An extinguisher is required whenever the boat has a permanently installed fuel tank or any vapor-trapping space. One exemption to know: outboard boats under 26 ft with portable fuel tanks, no passengers for hire, and no vapor-trapping spaces don't need one (USCG FAQ).

One 20-B substitutes for two 5-B. One 10-B does not count as two 5-B (USCG FAQ).

Other items that scale with size

Boats 26 ft and up with a machinery space must display an oily-waste pollution placard and a MARPOL trash placard; oceangoing boats 40 ft and up also need a written trash disposal plan. A toilet aboard means a Coast Guard-approved marine sanitation device. Registration numbers displayed and papers aboard are required items, too (USCG; VSC form ANSC 7008).

Boat-type deltas worth knowing

• Outboards are exempt from the backfire flame arrestor requirement, and the federal electrical systems subpart doesn't apply to them.
• PWC: wear PFDs marked for PWC or skiing use — Type III flotation aids are the designated category; inflatables generally aren't approved for PWC use per their labels (USCG; BoatUS Foundation). PWC ranked #2 in 2024 casualties (USCG Recreational Boating Statistics).
• Open sailboats under 26 ft without propulsion machinery and kayaks: night-only distress signals required where VDS apply.
• Inland, day-only boating: VDS carriage is only enforceable where VDS are required — but the USCG recommends carrying them anyway.

States may add requirements beyond the Coast Guard's — check your state boating office.

02Northern Europe: Sweden and Finland

There's no unified Nordic rulebook — each country sets its own carriage requirements, so check your own national authority if you boat elsewhere. Two named examples:

Sweden (Transportstyrelsen) frames equipment as situation-dependent — boat size, propulsion, season, weather, waters — and offers capability-based lists rather than a strict table: anchoring and mooring gear, navigation tools including paper charts as backup, type-approved nav lights plus a flashlight, a repair kit (knife, bailer, tools, through-hull plugs, fuses), a fire blanket and at least one 2-kg powder extinguisher (nothing below 5A/34B; total capacity generally ≥8A/68B), safety harness with tether, MOB gear, VHF with DSC, red hand flares, first aid, and flotation suits or a raft for abandonment. Life jackets for everyone aboard, worn by default whenever there's any risk of going in, and the kill-switch lanyard — dödmansgrepp — attached so the boat stops if the driver falls overboard. Sjöräddningssällskapet (the Swedish sea rescue society) adds: tell someone ashore your route and ETA, keep spare fuel, and carry your phone in a waterproof pouch for 112.

Finland (Traficom) requires motorboats and sailboats over 5 m to carry a suitably sized rescue life jacket or buoyancy aid for every person aboard, plus a bailing device or bilge pump, and — depending on size — paddles or oars, an anchor with line, an inspected hand extinguisher where required, registration documents, and charts where the route needs them (Traficom). Traficom's PFD classes: 50N for competent swimmers near shore (it does not turn an unconscious person face-up), 100N for sheltered waters, 150N for open water — the standard for inflatables — and 275N for harsh conditions. Finnish law also makes the skipper legally responsible for the boat's condition, the crew briefing, and keeping required equipment in good order and accessible (Traficom).

The contrast with the US is worth noticing: US law is a prescriptive equipment floor enforced by boarding; Nordic guidance is advisory and capability-based — match the gear to the trip — but expects life jackets worn, not just carried.

03Before every outing: the routine

This is the sequence that becomes habit. It takes ten minutes at the dock, and it's assembled from USCG, USCG Auxiliary, and Swedish rescue-society guidance:

1. Check the weather for the entire time you plan to be out, and keep an eye on it (NOAA buoys via the USCG app; Kustväder or Sjöfartsverket's ViVa in Sweden).
2. File the float plan with a responsible person ashore — route, crew, expected return, and a photo of the boat. Update them if plans change.
3. Fuel up, confirm a reserve; carry a spare can if Swedish guidance applies to you.
4. Sniff the bilge for fuel fumes. Run the blower before starting any gasoline engine — this is non-negotiable on inboard boats, and the ventilation ducts must be unblocked.
5. Check the battery: charge, cover, connections.
6. Test the bilge pump — flip the switch, listen. Confirm a bailing device aboard.
7. Drain plug in. The USCG calls this out as the classic forgotten item.
8. Test the nav lights and stow a spare flashlight or headlamp with extra batteries.
9. Count life jackets against souls aboard, correct sizes, stowed for ready access; throwable immediately available; children wearing theirs; inflatables showing green.
10. Extinguisher visible and charged — gauge in the green, pin in place, nozzle clear, no corrosion.
11. Attach the kill-switch lanyard to the driver.
12. Charts and route planned, tricky passages identified.
13. Brief your passengers (below), and cast off.

Two procedures belong on every checklist even though they're not equipment:

• The float plan. The USCG recommends one for everything from a 10-foot kayak to a 48-foot express cruiser. It tells local marine police or the Coast Guard where to look — and in a survival situation, time is of the essence. Downloadable fillable PDFs exist at uscgboating.org and floatplancentral.cgaux.org; the USCG mobile app can file one digitally.
• The passenger briefing. Show everyone where life jackets are, how the VHF or radio works, what to do if someone goes overboard. Swedish rescue guidance suggests giving people actual tasks; Finnish law makes the safety briefing a statutory skipper duty — persons aboard must be sufficiently instructed on safe conduct.

And a way to call for help: VHF with DSC, phone in a waterproof pouch, optionally a PLB or EPIRB. Note that the USCG's own mobile app — handy as it is — explicitly does not replace a VHF radio.

04Your first 10 minutes on someone else's boat

Renting or borrowing? You don't know this boat's quirks, so locate and test rather than assume:

1. Count wearable life jackets against passengers; check sizes for kids; inflatables showing green.
2. Find the throwable; confirm it's within reach, not locked away.
3. Find the extinguisher; gauge green, pin in, and check the date stamp against the 12-year rule.
4. Find and flip the bilge pump switch — listen for the pump.
5. Find the fuel shutoff and blower switch; run the blower before engine start on a gasoline boat.
6. Confirm the drain plug is in.
7. Test the nav lights and horn.
8. Find anchors, line, first-aid kit, tool kit.
9. Test the engine start and kill switch; find the VHF or phone pouch and note your position.
10. Ask the owner for a five-minute walk-through. Swedish sea rescue guidance stresses that used and rented boats often have "unique solutions" — fuel lines, drain plug location, engine behavior.

05The annual check: what quietly expires

The pre-departure routine catches loose ends; it doesn't catch slow decay. At least once a season — and monthly-to-seasonally for some items — inspect for degradation:

Skip the guesswork where the numbers don't exist: batteries don't come with a published service life, so check condition — charge, connections, corrosion, cover — rather than counting years.

06The Vessel Safety Check: free, voluntary, and worth doing

A VSC is a free exam of your boat by a certified vessel examiner from the USCG Auxiliary, America's Boating Club, or a state, at your boat — even your driveway — taking about 15–30 minutes depending on size (USCG Auxiliary).

The facts that make it easy to say yes, per the USCG Auxiliary: if your boat doesn't pass, no citation is issued — you get a written report on how to fix the discrepancies. Passing boats get a decal valid for the calendar year. Many insurers offer discounts for an annual VSC. And the exam form itself states, verbatim: "This is not an official boarding for law enforcement purposes."

That last point deserves emphasis: the VSC is not a law-enforcement boarding and carries no legal weight — it can't result in a citation. But the same equipment items, if found missing during a real Coast Guard or law-enforcement inspection, can result in a citation (USCG Auxiliary). The decal you earn simply signals to enforcement agencies that the boat was in full compliance with federal and state laws at check time.

The examiner works through 15 required categories (VSC form ANSC 7008): display of numbers, registration/documentation, PFDs, visual distress signals, fire extinguishers, ventilation, backfire flame control, sound-producing devices, navigation lights, pollution placard, MARPOL trash placard, marine sanitation device, navigation rules, state and local requirements, and overall vessel condition — deck free of hazards, clean bilge, electrical and fuel systems, galley and heating. Recommended discussion items include marine radio, dewatering devices and backup, anchor and line, first aid, capacity plate, charts, fueling practice, float plans, and boating classes.

To book: use the request form (an examiner will be located within 30 miles) or the "request a vessel safety check" feature in the USCG mobile app. Outside the US, there's no universal equivalent: Sweden's Transportstyrelsen publishes equipment guidance and Sjöräddningssällskapet promotes training and apps; Finland's Traficom assigns the responsibility to the skipper by statute rather than a voluntary-check scheme. Check what your own national authority offers.

07Why bother: the numbers

From the USCG's Recreational Boating Statistics 2024: drowning was the leading known cause of death — 365 deaths — and only 48 of those victims were wearing a life jacket. 310 were not. The top primary contributing factors were operator inattention (551 incidents), improper lookout (464), operator inexperience (436), and machinery failure (289). The USCG also notes that most boating drownings happen on nice days, and most fatalities occur when the boat is moving slowly or not at all.
