Distress signals & flares

What types of distress signals are available?

Pyrotechnic flares

Traditional flares that produce bright light or intense smoke. Common types include:

• Handheld red flares for close-range visibility
• Parachute rocket flares for long-distance aerial visibility
• Orange smoke signals for daytime location marking

These are highly visible but have a limited shelf life.

Electronic distress flares

Reusable electronic devices that emit powerful flashing SOS signals. They are:

• Safe to store
• Not pyrotechnic
• Long-lasting and reusable

Often used as a supplement to traditional flares. In many regions, pyrotechnic flares are still required by law for offshore voyages.

Smoke signals

Produce thick coloured smoke, usually orange, to mark position during the day. Especially effective for guiding helicopters or nearby vessels.

Light sticks

Chemical or LED light sticks provide low-level illumination and can help mark a position at night. They are not a primary distress signal but can support visibility.

Dye markers

Dye markers release bright green dye into the water, creating a large visible patch from the air. They are mainly used in daylight and calm conditions.

Which distress signal should I get?

Different signals work better in different conditions:

Carrying a mix increases your chances of being seen.

How should flares be stored on board?

They should be:

• Kept dry
• Stored in an accessible, waterproof container
• Checked regularly for expiry dates

Expired flares must be disposed of according to local regulations.
