Marine Flares UK — Types, Legal Requirements, and When to Use Them

I will be upfront — I have never had to fire a real flare in an emergency, and I am perfectly happy about that. But I have handled them in training, I know the different types, and I know that not understanding them before you need them is a serious mistake.

Here is everything you need to know, kept simple.

Do You Legally Need Flares on Your Boat in the UK?

For recreational vessels under 13.7 metres — not strictly, but it is more complicated than a flat no.

Sorry for technical jargon… somebody might be interested in this somewhere (like me). Under SOLAS Chapter V, which applies to all vessels including pleasure craft, you must carry means of making distress signals. Pyrotechnic flares are internationally recognised distress signals under COLREGS Annex IV. For vessels 13.7 metres and over, Wheel Mark certified flares are required by law. For commercial vessels, pyrotechnic flares are mandatory.

The RYA and MCA both strongly recommend flares for any coastal or offshore passage regardless of vessel size. On this one, they are absolutely right. Just carry them.

The Four Types of Flare — Explained Simply

Red Hand Flare — Probably more popular at a football match. Short range, day or night. Burns for about one minute. Used once rescuers are close to pinpoint your exact position. Hold downwind, arm out straight. They get very hot.

Red Parachute Rocket — long range. Fires to around 300 metres, deploys a parachute, burns for 40 seconds on the way down. This is your long-distance attention-getter — the first one you fire when nobody knows where you are yet. Read the instructions before you go to sea, not when you need it.

Orange Smoke — Also popular at football matches… Daytime only. Dense orange cloud visible to helicopters and aircraft. Floats on water, burns for three to four minutes. Completely useless at night.

White Hand Flare — not a distress signal. Used to warn other vessels you are there in close-quarters situations. Do not confuse it with a red flare in an emergency.

What About Electronic Flares?

Increasingly popular, and for good reason — they do not expire, are reusable, and have no disposal headache. However as of 2026 the MCA does not recognise electronic flares as a substitute for pyrotechnics. Carry them in addition, not instead. MCA guidance on electronic flares.

Which Pack Do You Need? – Keep it simple

Inshore — Day sailing in local waters. 2 red hand flares, 2 orange smoke.

Coastal — coastal cruising or cross-channel passages. 2 red hand, 2 orange smoke, 2 parachute rockets.

Offshore — serious offshore passages. 4 red hand, 2 buoyant orange smoke, 4 parachute rockets.

Match the pack to where you are actually going, not the minimum you can get away with.

Expiry Dates — Check Them

Flares expire — typically three years from manufacture in the UK. An expired flare may not fire or may perform unpredictably. Check the date on every flare before every passage and replace before expiry. The MCA operates a flare disposal service — do not put them in household bins. Find your nearest disposal point via HM Coastguard.

Before You Go to Sea — Read the Instructions Now

Every flare has firing instructions printed on the side. Read them at home, in daylight, when you are calm. In an emergency your hands will be cold, you may be in an immersion suit, and you will not be at your best. Know what to do before you need to do it. and they should really be part of your offshore safety checklist.

Reputable specialists

For UK flare packs, always buy from a reputable specialist marine safety supplier rather than a general retailer. You need to be certain your flares are in date, correctly certified, and properly stored. Ocean Safety, Suffolk Marine Safety, and your local chandler all stock coastal and offshore packs from trusted brands like Pains Wessex.

FAQs

Can I use out of date flares in a real emergency?
Yes — something is better than nothing. But replace them before expiry so you never have to rely on an expired one.

Can I test a flare?
No safe way to test a pyrotechnic. Check the expiry date and packaging condition — that is your only check.

Where should I store flares on board?
In a waterproof container, easily accessible from the cockpit. Not in a locker you cannot reach in 30 seconds.

Always verify current flare requirements for your vessel at gov.uk/mca and rya.org.uk. Regulations are reviewed periodically.
