Marine Safety Equipment UK — Complete Guide
Marine Safety Equipment UK — Complete Guide
Marine safety equipment is not one thing. It is a system of interconnected kit — each item doing a specific job that the others cannot do. Understanding what each piece does, why it matters, and what UK law actually requires is what this guide is for.
I have worked offshore for nearly two decades. I have used most of this equipment in training and some of it in real situations. Here is the honest guide to what you actually need on a UK vessel.
The Core Categories of Marine Safety Equipment
Marine safety equipment falls into five broad categories:
Personal safety — equipment worn by or attached to individuals. Lifejackets, harnesses, personal PLBs, immersion suits.
Distress and location — equipment that alerts rescuers and helps them find you. EPIRBs, PLBs, SARTs, flares, VHF radios with DSC.
Survival — equipment that keeps you alive once you have abandoned the vessel. Liferafts, grab bags, immersion suits, thermal protection.
Fire safety — equipment that detects and suppresses fire on board. Fire extinguishers, fire blankets, smoke detectors, fixed suppression systems.
Navigation and communication — equipment that helps you avoid emergencies and communicate when they happen. VHF radio, AIS, GPS chartplotter, radar.
What UK Law Actually Requires
This is where most guides are either vague or wrong. Let me be specific.
For commercial vessels, requirements are set out in the applicable MCA code of practice — the new consolidated Sport or Pleasure Vessel Code that came into force December 2025 replaced the old Blue, Yellow, and Red codes. Commercial vessels must carry specified safety equipment appropriate to their area of operation and passenger numbers.
For recreational vessels under 13.7 metres, the position is more complicated. Under SOLAS Chapter V, which applies to all vessels including pleasure craft, you must carry appropriate navigation equipment and means of making distress signals. Beyond that, there is no statutory list of required safety equipment for recreational craft under 13.7 metres in UK waters.
This does not mean you should not carry it. The absence of a legal requirement is not the same as the absence of a need.
Lifejackets and Buoyancy Aids
Every person on board needs a correctly sized, correctly rated personal flotation device. For offshore and coastal sailing — a 150N or 275N automatic inflation lifejacket. For dinghy sailing and sheltered water — a 50N buoyancy aid is the standard but understand what it does and does not do.
A lifejacket turns you face up even unconscious. A buoyancy aid helps you swim assuming you are conscious. Know which you have and match it to the conditions.
Newton ratings — 50N for sheltered inshore waters, 100N for coastal use in light clothing, 150N for coastal and offshore, 275N for commercial offshore in heavy PPE. Check out the best life jackets, in our opinion Here.
EPIRB and PLB
An EPIRB is registered to the vessel and calls for help via satellite when the vessel is in distress. A PLB is registered to the person and goes wherever they go.
For any offshore or extended coastal passage — carry both. The EPIRB covers the vessel. The PLB covers each crew member individually if they end up separated from the vessel.
Both must be registered with the UK Beacon Registry before use.
Liferaft
A liferaft is your last resort when the vessel is no longer survivable. For recreational vessels under 13.7 metres there is no statutory requirement for a liferaft in UK waters — but for any offshore passage it is an essential piece of equipment.
Size it for your maximum possible crew, not your typical crew. Service it annually. Store it on deck in a hydrostatic release cradle, not below decks.
Flares
Pyrotechnic flares remain the recognised means of making visual distress signals under COLREGS. For inshore use — a minimum of two red hand flares and two orange smoke. For coastal use — add two parachute rockets. For offshore — four red hand, two buoyant orange smoke, four parachute rockets.
Check expiry dates before every passage. Flares typically last three years from manufacture.
VHF Radio
A fixed DSC VHF radio is essential for any serious coastal or offshore passage. It connects to your GPS chartplotter and allows you to send an automatic distress alert including your position at the press of a single button. A handheld VHF is a useful backup and for communication in the cockpit or on deck.
Register your vessel with OFCOM for a Ship Radio Licence and MMSI number before using any VHF radio. More information on the DSC Here.
Fire Extinguishers and Fire Safety
At minimum — one CO2 extinguisher for electrical and engine fires, one dry powder for general use, and a fire blanket in the galley. For vessels with enclosed engine rooms, a fixed CO2 suppression system is standard.
Fit smoke detectors below decks. Check extinguisher pressure gauges regularly. Service on the manufacturer’s schedule. More details here.
The Grab Bag
The grab bag is what you take with you if you have to abandon ship. PLB, handheld VHF, flares, water, first aid kit, torch, whistle, warm clothing. Bright coloured, waterproof, accessible from the cockpit.
AIS
AIS — Automatic Identification System — broadcasts your position to other vessels and receives theirs. Not legally required for recreational craft but enormously useful for collision avoidance particularly at night and in poor visibility. Class B units are appropriate for recreational use.
Complete Equipment Checklist
Personal safety: lifejacket for every person, safety harness for offshore passages, PLB for each crew member offshore, immersion suit for offshore passages in cold water.
Distress and location: EPIRB registered and mounted, flares in date, handheld VHF, fixed DSC VHF radio connected to GPS.
Survival: liferaft sized for maximum crew, grab bag packed and accessible, immersion suits accessible on deck.
Fire safety: fire extinguishers per main area, fire blanket in galley, smoke detectors below decks.
Navigation: up to date charts including paper backup, compass, GPS chartplotter, AIS.
FAQs
What marine safety equipment is legally required on a recreational yacht in the UK?
Under SOLAS Chapter V — appropriate navigation equipment and means of making distress signals. Beyond that, for recreational craft under 13.7 metres, there is no statutory list of required equipment. The MCA and RYA publish recommended equipment lists which should be treated as the practical standard.
Does all marine safety equipment need to be SOLAS approved?
For commercial vessels operating under the relevant MCA codes — yes, specified equipment must meet relevant standards. For recreational use, equipment certified to relevant ISO standards is the appropriate benchmark. Always check the specific standard required for your vessel type and area of operation.
How often should marine safety equipment be serviced?
Liferafts annually, EPIRBs every five years, fire extinguishers annually or per manufacturer schedule, flares replaced before expiry date, lifejacket inflation cylinders and bobbins checked annually.
Always verify current requirements for your specific vessel and area of operation at gov.uk/mca and rya.org.uk.
