There are two safety equipment lists for every boat: the one the law requires, and the one that actually gets you home. This guide covers both — the US Coast Guard minimums by boat size, and the gear experienced sailors carry beyond them — plus a free interactive checker that builds your boat’s list in thirty seconds.
What safety equipment is required on a boat?
For recreational boats in US waters, the Coast Guard minimum comes down to five things: life jackets (a wearable, properly-sized one per person, plus a throwable cushion or ring on boats 16 ft and over), fire extinguishers on most powered boats, a sound-producing device (whistle, horn, or bell), visual distress signals on coastal waters (flares or an approved electric signal), and navigation lights for operation between sunset and sunrise. State rules add to this — many require children to wear life jackets, and some add engine cut-off switch and education requirements.
Sailing under another flag? The categories are near-universal even where the details differ — Transport Canada, for instance, adds a buoyant heaving line and bailer. Check your own flag state; the checker below covers the US rules.
Required equipment by boat size
USCG requirements scale with length. The quick version:
| Boat length | Beyond the universal minimums, add |
|---|---|
| Under 16 ft | night visual distress signals for coastal night operation; one 5-B extinguisher if powered |
| 16 to 26 ft | a throwable flotation device; day and night visual distress signals; one 5-B extinguisher if powered |
| 26 to 40 ft | two 5-B extinguishers (or one 20-B); a bell or whistle audible half a mile |
| 40 to 65 ft | three 5-B extinguishers (or 20-B + 5-B); bell and whistle; placard requirements |
Rather than memorize the table, use the free Safety Equipment Checker: pick your boat length and where you sail, and it prints your boat’s required and recommended list.
The list that actually saves you
Nobody ever drowned because they lacked a placard. The legal minimums assume help is minutes away; the moment you sail somewhere it is not, the real list begins: a life raft sized to the crew, an EPIRB or PLB (registered — an unregistered beacon costs rescuers hours), MOB recovery gear you have actually practiced with, jacklines and tethers rigged before you need them, a proper first-aid kit with someone aboard who has opened it, manual bilge backup, and redundant comms — VHF plus something satellite. And the one item that weighs nothing: a float plan left with someone ashore.
The part everyone forgets: expiry dates
Safety gear ages invisibly. Flares expire after 42 months. Extinguishers have a 12-year life and want annual checks. Life rafts need professional service every one to three years. EPIRB batteries expire. First-aid kits get raided for headaches and never restocked. The failure mode is not owning the gear — it is discovering, mid-emergency, that the gear you own expired two seasons ago.
This is what WatchKeeper’s Safety Locker is for. Every item aboard, with its location, service dates, and expiry reminders — and your float plan pulls the equipment list automatically, so rescuers would know exactly what you carry. Free to start on the Coastal tier.

Boat safety equipment FAQ
What safety equipment is required on a boat?
For most US recreational boats the Coast Guard minimum is: a wearable life jacket for every person aboard (plus one throwable device on boats 16 ft and over), a fire extinguisher on most powered boats, a sound-producing device, visual distress signals on coastal waters, and navigation lights if you operate after dark. Requirements scale with boat length, and states can add their own — so check both USCG and state rules for your boat.
What safety equipment does a boat under 16 feet need?
A wearable life jacket for each person, a sound-producing device such as a whistle or horn, navigation lights if operated between sunset and sunrise, visual distress signals for night use on coastal waters, and a fire extinguisher if the boat has an engine or enclosed fuel. Children under 13 must wear their life jacket while underway on most waters.
How many fire extinguishers does a boat need?
It scales with length: boats under 26 ft with an engine generally need one 5-B rated extinguisher, boats 26–40 ft need two 5-B (or one 20-B), and boats 40–65 ft need three 5-B (or one 20-B plus one 5-B). Extinguishers must be less than 12 years old, and fixed engine-room systems can substitute for one unit.
What is the difference between required and recommended safety equipment?
Required equipment is the legal minimum to avoid a citation. Recommended equipment is what actually changes outcomes offshore: a life raft, an EPIRB or PLB, a first-aid kit, tools and spares, a bilge pump backup, jacklines and tethers, and a float plan left with someone ashore. The law defines the floor, not the standard of seamanship.
Do safety equipment requirements change for offshore sailing?
Legally, visual distress signal rules apply on coastal waters, and beyond that USCG minimums change little — but the real requirements change completely. Offshore, self-rescue is the plan: life raft, EPIRB, MOB recovery gear, storm sails, drogue or sea anchor, and redundant communications. Race regulations like World Sailing Offshore Special Regulations are a good checklist even for cruisers.
How do I keep track of my boat safety equipment and its expiry dates?
Flares, extinguishers, life raft service, EPIRB batteries, and first-aid contents all expire on different schedules — a paper list taped in a locker rarely stays current. A digital safety locker with expiry reminders solves it: WatchKeeper tracks every item and its service dates, and your float plan pulls the equipment list automatically.
