Lesson 1 of 6
What you will learn
Choose, fit and use personal safety equipment for the task, and organise the first response if someone falls overboard.
Personal safety starts before the emergency: wear the right flotation, clip to a suitable strong point before exposure, and use the engine cut-off device exactly as intended.
Level 150 lifejackets are intended for coastal and offshore use and are designed to help turn an unconscious wearer face-up. That performance still depends on choosing the right size and buoyancy for the activity, wearing the jacket snugly over the actual clothing, fastening semi-tight crotch straps, checking its condition and following the maker's servicing interval. Level 275 is aimed at extreme offshore conditions, especially with heavy or air-retaining clothing; it is not automatically the best choice for every trip.
A safety line connects a correctly fitted harness to a purpose-made strong point or jackstay. Clip on before leaving the safer area. Use the shortest suitable tether and a route that reduces the chance of reaching the water; guardrails are not harness attachment points and jackstays should be kept close to the centreline where practicable. Remaining attached is not the same as being safe: a person dragged alongside can still drown, so stop the vessel if a tethered person enters the water.
Where a kill cord is fitted, the driver wears it whenever the engine is running and tests it at the start of the day or session. Turn the engine off before changing driver, then attach the cord to the new driver before restarting. Do not clip the cord to loose clothing or lengthen it beyond the engine maker's arrangement.
If someone falls overboard unattached, raise the alarm immediately, deploy buoyancy, appoint one person to keep pointing, mark the position and slow or stop the vessel while the skipper organises communications, approach and recovery. The exact manoeuvre and recovery method depend on the boat and conditions, so every crew needs a rehearsed plan and usable recovery equipment.
It is getting dark and the sea is building. One crew member may need to leave the cockpit while another will later drive the tender.
1. Fit
Check that each lifejacket is the right size, snug over the worn layers, in serviceable condition and secured with its crotch straps.
2. Clip
Agree the strong points, jackstay route and shortest suitable tether before anyone moves onto the exposed deck.
3. Cut the engine
Test and wear the tender's kill cord; stop the engine before transferring control to another driver.
Sense check: The plan should prevent separation from the boat where possible and still explain how the crew will stop, locate and recover a casualty if prevention fails.

Lesson 2 of 6
What you will learn
Select MAYDAY, PAN PAN or a safety message and carry out the DSC-to-voice distress sequence without assuming one device guarantees rescue.
The priority signal describes the situation: MAYDAY is for grave and imminent danger requiring assistance, while PAN PAN covers urgent safety concerns that have not reached that threshold.
For grave and imminent danger when assistance is required, send the VHF DSC distress alert on Channel 70 by pressing and holding the covered control until the set confirms it has sent. The alert identifies the vessel by MMSI and can include position and time when valid navigation data reaches the radio. It carries the selected nature of distress, or an undesignated distress if none was selected.
On receiving a DSC acknowledgement, or after about 15 seconds, transmit the voice distress call and message on Channel 16 when circumstances permit. Give MAYDAY three times, vessel name three times, call sign or other identity and MMSI, then repeat MAYDAY and give vessel identity, position, nature of distress, assistance required, number of people on board and other useful information before OVER.
PAN PAN is for an urgent concern about the safety of a person or vessel that does not meet the MAYDAY threshold. Current MCA small-boat guidance uses a DSC All Ships Urgency call with a nominated working channel, an announcement on Channel 16 and the full message on that working channel. Safety information follows the radio's supported safety-call procedure or a voice call on Channel 16 before moving as directed.
An EPIRB transmits a 406 MHz distress alert by satellite; GNSS-equipped units can include position. An EPIRB or 406 MHz PLB carried on a UK-registered ship or watercraft must be registered with the UK Beacon Registry and kept up to date. A radar SART is a close-range locating aid. VHF range depends strongly on antenna height, so use the appropriate available alerting and locating methods rather than assuming one device guarantees contact or immediate rescue.
Worked example
The yacht is taking water faster than the pumps can control it and the crew may have to abandon. A fixed VHF with valid position data and DSC is available.
Sense check: If the spoken message does not tell rescuers who, where, what is wrong, what help is needed and how many people are involved, it is not yet a useful MAYDAY message.
| Signal | Use it when | Initial voice route |
|---|---|---|
| MAYDAY | Grave and imminent danger; assistance required | DSC distress alert, then Channel 16 voice message |
| PAN PAN | Urgent safety concern below the MAYDAY threshold | DSC urgency announcement, Channel 16 call, then nominated working channel |
| Safety message | Navigational, weather or other safety information | Supported DSC safety procedure or Channel 16 voice call, then the directed channel |
A stable yacht has a crew member with a suspected fracture. The vessel remains under control, but medical advice or assistance is needed and the situation could deteriorate.
1. Assess
Decide whether there is grave and imminent danger now or an urgent safety concern that has not reached that point.
2. Alert
Use the radio's appropriate DSC priority and the current voice sequence; do not use Channel 70 for speech.
3. Update
Escalate to MAYDAY if the situation becomes grave and imminent, and tell the responding station about material changes.
Sense check: The priority describes the real risk, not how dramatic the event feels. A PAN PAN can become a MAYDAY if the danger changes.

Lesson 3 of 6
What you will learn
Choose an alerting or locating signal for the visibility and rescue stage, and dispose of expired flares through a current lawful route.
Visual distress signals do different jobs: a rocket can alert at long range, while a hand flare or smoke signal helps rescuers locate the casualty more precisely.
A compliant red rocket parachute flare fired vertically reaches at least 300 metres and burns bright red for at least 40 seconds, making it a long-range alerting signal. A compliant red hand flare burns for at least one minute and helps a known approaching rescuer pinpoint the casualty. A buoyant smoke signal emits highly visible smoke for at least three minutes in calm water and is primarily a daylight locating signal.
A white hand flare is not a recognised distress signal. It can warn another vessel of your presence or a collision risk, but it must not be mistaken for a red distress signal. Signal choice must account for day or night, visibility, whether help is already searching nearby and the vessel's actual carriage requirements.
Read the maker's instructions before an emergency, keep signals dry, accessible and in date, and fire them only when the emergency and chance of detection justify it. Do not dismantle, test-fire or place expired signals in ordinary waste.
HM Coastguard stopped accepting unwanted flares from private individuals in January 2023. Use a confirmed third-party or take-back route such as a supplier, marina, liferaft service, local authority or suitable waste business, and check acceptance before transporting the flares.
| Signal | Primary job | Key distinction |
|---|---|---|
| Red parachute rocket | Long-range alert | At least 300 m and 40 seconds when compliant and fired vertically |
| Red hand flare | Close-range location | Bright red for at least one minute |
| Buoyant orange smoke | Daylight location | Highly visible smoke for at least three minutes in calm water |
| White hand flare | Collision warning | Not a recognised distress signal |
The distress alert has been received and a rescue aircraft is searching nearby in daylight, but it has not yet located the yacht.
1. Confirm
Use radio information and visual contact to judge whether the rescuer is close enough for a locating signal to be useful.
2. Select
Choose daylight smoke or another suitable locating signal rather than automatically firing a long-range rocket.
3. Operate
Follow the exact maker's instructions, keep people clear and continue communications as directed.
Sense check: The best signal is the one the intended rescuer can detect at that stage; firing every signal immediately can leave none for later location.

Lesson 4 of 6
What you will learn
Prevent common onboard fires and make an alarm-isolate-escape decision using an extinguishing medium suited to the burning material.
On a boat, the first fire-fighting decision is whether the fire can be attacked without losing the escape route. Raise the alarm and protect people before trying to save the vessel.
Prevention starts with maintained fuel and electrical systems, clean bilges, correctly installed gas equipment, secured flammable liquids and cooking that is never left unattended. Fire extinguishers must be visible, accessible and positioned so a crew member does not have to move through the fire to reach one; keep a suitable fire blanket close to cooking facilities.
The fire triangle is a decision model: sustained fire needs fuel, heat and oxygen. Safely shutting off gas or fuel removes the fuel supply; cooling removes heat; closing a space or stopping ventilation can reduce oxygen. None of these actions is worth trapping a crew member or feeding the fire by opening the wrong hatch.
Use an extinguishing medium rated for the burning material. Water is for suitable Class A solid-material fires and must not be used on liquid, gas or electrical fires. Dry powder can cover several classes but creates residue, reduces visibility and can affect breathing. CO2 can be effective on small Class B and live electrical fires, but it disperses in the open and can create an asphyxiating atmosphere in a confined space. A fire blanket can be effective on a small cooking-oil or pan fire when it can be applied without leaning into danger.
If fire is discovered, shout the alarm, account for the crew and keep the escape route behind you. Stop engines, fuel, gas, electrical supply or ventilation only where it is safe and appropriate; use the correct equipment from a protected position. Make the distress call early if people or vessel are in grave and imminent danger, and prepare to abandon if the fire cannot be controlled.
A small flame appears at the galley cooker. The gas shut-off is reachable without passing the fire and a fire blanket is beside the companionway.
1. Alarm
Call out, make sure the crew can escape and keep the companionway clear.
2. Isolate
If it remains safe, shut off the gas supply and avoid opening or ventilating a space in a way that feeds the fire.
3. Control or leave
Use the suitable blanket or extinguisher from the escape side; withdraw, call MAYDAY and prepare to abandon if control is doubtful.
Sense check: If reaching the shut-off or extinguisher means passing the fire, or smoke and heat are increasing, the attack plan has already failed its safety check.

Lesson 5 of 6
What you will learn
Prepare the yacht for helicopter winching, follow the aircrew's course and speed, and handle a hi-line without securing it or taking a static shock.
A helicopter rescue is directed by the aircraft crew. The yacht's job is to provide a clear working area, obey the requested motion and keep every line and person free of obstructions.
Maintain the listening watch on Channel 16 or the frequency specified and repeat the aircraft's requested course, speed and working area. Clear loose gear before the helicopter arrives and keep people away from the winching area unless they have an assigned job. Do not invent a universal heading or stop the vessel unless directed; the safe profile depends on the aircraft, wind, sea, vessel and casualty.
A hi-line is a light line used to guide the winchman or strop when the helicopter cannot hover directly overhead. Tend it, keep it clear of obstructions and feed or recover slack as directed. Never secure a hi-line or winch wire to the yacht and never wrap it around a person or hand.
The wire and the person being lowered may carry a dangerous static charge. Do not touch either until earthing or discharge has occurred and the aircrew or winchman directs contact. The safe action is to follow the live instruction, not to assume that the wire must always be made to touch a particular part of the yacht first.
Once aboard, the winchman controls the transfer. Keep the working area clear, continue the requested course and speed, and report any fouled line or new hazard immediately. Never cut a fouled wire unless the helicopter crew directs it.
A rescue helicopter is approaching a yacht with one injured crew member. The aircraft asks for a steady course and says a hi-line will be used over the aft deck.
1. Confirm
Read back the requested course, speed, working area and any instructions about aerials, sails or lighting.
2. Clear
Secure loose gear, move unassigned people away and nominate one crew member to tend the hi-line.
3. Follow
Keep the line free, never make it fast, avoid contact until discharged or directed, and obey the winchman's transfer instructions.
Sense check: The yacht should not control the aircraft through a secured line; every part of the arrangement must allow the helicopter to move away immediately.

What you will learn
Build and brief an accessible safety-equipment plan matched to the vessel, crew, operating area, passage and applicable rules.
A useful safety inventory is risk-based and usable under pressure. Equipment that is inappropriate, overdue, buried or unknown to the crew does not complete the plan.
Start with the vessel, number and needs of the people aboard, operating area, distance from help, weather, water temperature, daylight, passage length and the rules that apply. A coastal yacht may need correctly fitted lifejackets, harnesses and tethers, suitable alarm and locating methods, fire-fighting equipment, first aid, sound signalling, lighting, communications and a practical means of recovering a person from the water. The exact carriage requirement is not identical for every pleasure vessel or voyage.
For a UK pleasure vessel under 13.7 metres, a liferaft is not automatically mandatory, but the decision should consider distance from other boats and emergency services, water temperature, weather and the consequences of fire or sinking. Choose, stow and service any raft for the actual people and passage; it must be accessible and launchable by the crew who may need it.
A grab bag supplements the equipment already packed in the raft. Its contents therefore depend on the raft, passage and people. Prioritise raising and maintaining the alarm, helping rescuers locate you, protection from exposure, medical needs, then food and water. It may include a registered EPIRB or PLB, waterproof handheld VHF, suitable signals, torch, thermal protection, first aid, medication, water and a safety knife. Keep it accessible, waterproof or buoyant as appropriate, secured and complete.
The departure briefing should show where equipment is, who uses it and what triggers each emergency plan. Check dates, batteries, service indicators and physical access; practice person recovery and make sure someone other than the skipper can raise the alarm and control the vessel. Abandon only when remaining aboard is more dangerous and follow the skipper's or rescue service's direction where available.
A family crew is preparing a cold-water coastal passage that will finish after dark, with one person taking medication and only two experienced helms.
1. Match
Review the passage risks, legal requirements, crew sizes, clothing, medical needs, communications coverage and recovery method.
2. Inspect
Check fit, condition, dates, charge, registration, service state and whether the weakest crew member can reach and deploy the equipment.
3. Brief
Point to each critical item, assign alarm and recovery roles, and explain what changes the plan or triggers abandonment.
Sense check: Ask a crew member to locate the distress controls, fire equipment, first aid, recovery gear and grab bag without help. Any hesitation reveals a preparation gap.
