Lesson 1 of 8
Lifejacket Job and Readiness Chain
What you will learn
Distinguish the job of a lifejacket from a buoyancy aid and use a six-stage readiness chain instead of treating any personal flotation device as complete protection.
Personal flotation starts with the job, then the person, task, actual unit, fit and boat response. A lifejacket is designed to support flotation and turn an unconscious wearer towards a face-up position; a buoyancy aid supports an active person but is not designed to do that job.
The words describe different performance intentions. The RYA describes lifejackets as designed to turn an unconscious person face up and keep the mouth and nose clear; buoyancy aids support flotation where entering the water and active self-recovery are expected, but will not turn an unconscious person face up. Designed to is not the same as guaranteed for every person, garment, sea state or recovery delay.
Selection is only the first link. The unit has to be within its intended scope and size range, in serviceable condition, worn before sudden immersion, adjusted over the current clothing and connected to a crew plan for alerting and recovery. A light, sprayhood, whistle, harness attachment or personal locating aid can add functions only when compatible and understood.
The readiness chain is: select the job; match the person and activity; inspect the actual unit; fit it over current layers; confirm accessories and the crew response; recheck after any change. A failure at one link is not cancelled by strength at another.

Readiness is a chain. A suitable product that is not worn, a correctly worn unit with a fault, or a working lifejacket without a recovery plan each leaves a different gap.
Decision
Choose personal flotation for the actual sailing task, likely recovery delay, night conditions, person, clothing and manufacturer scope. A lifejacket and a buoyancy aid do different jobs.
Check the evidence
Confirm the correct device, approval and size range; activation type; current inspection and service state; fit over the clothing being worn; and compatible light, sprayhood, whistle, harness or personal locating aid where the plan requires them.
Do not assume
A Newton label or the word lifejacket alone does not prove fit, automatic activation, face-up performance for this person and clothing, recovery capability or suitability for every activity.
Aboard action
Allocate the unit to a named wearer, fit it before risk conditions, and include its controls and the boat's recovery response in the departure brief.
Choose a changing case and compare the supported decision, evidence check, unsafe assumption and next aboard action.
Worked example
A guest is given the nearest inflatable lifejacket for an overnight coastal passage. It closes over a thick jacket, but nobody checks the stated size range, activation type, service status, crotch strap or recovery plan.
- 1Start with the job: an unexpected immersion at night where self-recovery and immediate assistance cannot be assumed.
- 2Match the named wearer and clothing to the exact model's size and use limits; do not infer suitability from the buckle closing.
- 3Inspect and fit the unit using its instructions, then include the light, sprayhood, manual control and boat recovery roles in the brief.
- 4If any link cannot be confirmed, withdraw that unit and provide a known-suitable, known-ready alternative before exposure begins.
Sense check: The decision has not promised face-up performance or rescue; it has converted a generic handout into a named, checked and briefed safety system.
| Link | Evidence | Unsafe shortcut |
|---|---|---|
| Job | Expected immersion, ability to self-help, operating area, visibility and recovery delay | Use any item labelled PFD for every activity |
| Person + task | Stated size and performance scope, clothing, mobility and manufacturer's limitations | Choose by body weight or Newton label alone |
| Actual unit | Cover, bladder evidence, straps, cylinder, firing head, dated items and service record | Assume a tidy cover proves internal readiness |
| Fit + wear | Model donning instructions, snug adjustment and secured crotch or thigh straps | Keep it in a locker until conditions worsen |
| Crew plan | Controls, accessories, alerting, location and person-capable recovery rehearsed | Assume flotation automatically returns the person aboard |
Run the chain for a named wearer
A locker contains several different lifejackets and buoyancy aids, while the crew has different sizes, layers and deck tasks.
1. Name the job
State the activity, entry likelihood, ability to self-help, operating conditions and likely recovery route.
2. Allocate and check
Match and inspect one actual unit for one person rather than briefing the locker as a group.
3. Fit and respond
Fit it over current layers and brief controls, accessories, alerting and recovery roles.
Sense check: A complete chain answers who will wear which checked unit, when, and how the rest of the crew will respond.
Common mistake or limitation
- Using lifejacket, buoyancy aid and PFD as if they guaranteed the same performance.
- Selecting on a Newton label, price or appearance without the person, clothing, activity and instructions.
- Treating flotation as a substitute for preventing the fall, raising the alarm and recovering someone unable to help.
Recap
- Start with the required job, not the nearest item in the locker.
- A suitable product still has to be inspected, worn, fitted and integrated with the crew response.
- No single label, feature or accessory completes the readiness chain by itself.

Lesson 2 of 8
Select for the Person, Task and Clothing
What you will learn
Compare lifejacket, buoyancy-aid, activation and performance choices using the intended job and limitations rather than a universal rule.
Selection is contextual. Consider whether water entry is expected, whether the person can actively self-rescue, the operating area, visibility, weather, clothing, recovery delay, body size and the exact product standard and instructions.
A buoyancy aid is intended for activities where entering the water is likely, help is nearby and active self-recovery is expected. A lifejacket is intended to provide more airway-supporting performance, including an unconscious-wearer turning function. A yacht passage, dinghy capsize drill and personal-watercraft activity therefore do not begin with the same choice.
Inflatable lifejackets may be manual, water-activated or pressure-activated, with an oral tube for top-up or backup. Activation choice changes the failure and accidental-inflation picture; it must come from the activity, product instructions and competent advice, not a memorised claim that automatic or manual is always safer.
Buoyancy level and approved standard matter, but the printed number is not a complete selection calculation. RYA guidance distinguishes higher-performance products for more severe conditions and heavy or air-retaining clothing. Confirm the model's intended user range, compatible clothing and limitations rather than converting Newtons into a guaranteed outcome.
Worked example
The same person plans a supervised dinghy session close to assistance and an overnight yacht passage wearing foul-weather clothing.
- 1For each activity, state whether water entry is expected, active swimming or self-recovery is part of the activity, and how quickly capable help is likely.
- 2Compare the personal-flotation category, performance level, activation method, mobility and clothing scope using the exact product guidance.
- 3Check the real unit and fit for each use; do not carry the dinghy decision over to the yacht passage without reassessment.
Sense check: The learner has used context to create two selection questions, not declared one type universally best.
| Choice evidence | Question | Do not infer |
|---|---|---|
| Water entry + self-help | Is entry expected, and can this person actively keep afloat and recover? | All buoyancy devices turn an unconscious person |
| Area + conditions | How exposed, dark, cold or delayed might recovery be? | The same device is suitable inshore and offshore |
| Clothing + person | Does the exact model cover this wearer and current layers? | One size or one Newton value fits every body and garment |
| Activation | What does the model do automatically and what must the wearer do? | Manual or automatic is universally superior |
Change one variable at a time
A regular coastal wearer adds heavy, air-retaining protective clothing for a colder passage.
1. Reopen selection
Treat changed clothing and conditions as new evidence, not a reason to loosen the old jacket until it closes.
2. Check scope
Use the stated clothing, size and performance guidance for the exact model and seek competent advice where it is unclear.
3. Refit and brief
Fit the chosen unit over the new layers and recheck controls, accessories and recovery implications.
Sense check: A change in clothing can change selection as well as strap adjustment.
Common mistake or limitation
- Calling a buoyancy aid a lifejacket and assuming an unconscious-wearer turning function.
- Declaring automatic inflation always right or manual inflation always safer without the activity and model.
- Treating the stated Newton value as a person-specific guarantee or a recovery plan.
Recap
- Different activities create different personal-flotation jobs.
- The person, current clothing, product scope and activation method belong in the same selection decision.
- Use exact instructions and competent advice where the combination is uncertain.

Lesson 3 of 8
Fit and Crotch Straps
What you will learn
Fit a named lifejacket over the clothing actually worn, perform a model-led buddy check and explain why waist and crotch or thigh adjustment work together.
Fit keeps the buoyancy where the design expects it. Secure the exact unit according to its instructions, adjust it snugly over current layers and use fitted crotch or thigh straps; then recheck whenever the wearer or clothing changes.
RYA guidance says the collar should sit comfortably, straps should be free from twists, the waist strap should be comfortably tight and the crotch straps semi-tight while allowing movement. The unit is fitted over the clothing being worn, and the adjustment is revisited when layers change.
Waist or chest adjustment restrains the body of the unit; crotch or thigh straps resist upward ride-up. They are a system, not alternatives. Loose or dangling crotch straps can snag, while an unused strap cannot control ride-up. Follow the supplied arrangement rather than inventing a knot or passing webbing through an unapproved point.
The Copious investigation provides a concrete boundary: the waist strap was set far looser than the wearer and the fitted crotch strap was taped away. When the casualty became unconscious, the lifejacket rode up and did not keep the airway clear. The case supports correct fit and training; it is not a universal prediction of what every jacket will do.
Worked example
A crew member puts a previously adjusted lifejacket over an extra mid-layer and foul-weather jacket. The buckle closes, but the crotch strap hangs loose and the collar has shifted.
- 1Confirm that the wearer and clothing remain within the exact model's stated range; closing the buckle is not enough.
- 2Redon using the model sequence, remove twists, seat the collar, secure the buckle and adjust the waist or chest strap snugly.
- 3Route and adjust the supplied crotch or thigh straps as instructed, then check movement and access to controls.
- 4If correct fit cannot be achieved without defeating another function, withdraw the unit and issue a suitable alternative.
Sense check: The crew has not copied another person's strap setting or treated a closed buckle as proof of correct fit.
| Buddy-check point | Supported evidence | Fault response |
|---|---|---|
| Identity + range | Named wearer and current clothing are within the model instructions | Provide a suitable alternative; do not merely loosen the strap |
| Collar + cover | Correct orientation, no trapped garment, twist or visible damage | Redon correctly or withdraw the damaged unit |
| Waist/chest | Buckle closed and strap snug according to the model | Readjust for the current wearer and layers |
| Crotch/thigh straps | Supplied straps secured, correctly routed and adjusted as instructed | Stop loose, taped-up, dangling, twisted or improvised use |
| Movement + controls | Wearer can move and identify manual and oral controls without loosening fit | Rebrief or change the equipment combination |
Make the buddy check observable
Before night sailing, the skipper asks, ‘Everyone happy with their lifejackets?’ and receives four quick yes answers.
1. Name pairs
Pair crew and check the assigned unit over the actual night clothing.
2. Touch points
Verify collar, buckle, waist or chest adjustment, crotch or thigh straps, twists and visible damage in a fixed order.
3. Confirm controls
Each wearer identifies the model's manual control and oral tube without disturbing the fit.
Sense check: A buddy check produces observable evidence; it is not a confidence poll.
Common mistake or limitation
- Copying the previous wearer's strap setting or checking only that the buckle closes.
- Leaving a supplied crotch strap taped, dangling, twisted or unused because the water looks calm.
- Using the crotch strap as a lifting strap; its fit function does not prove a lifting rating.
Recap
- Fit the actual wearer over the current layers using the exact model instructions.
- Waist or chest and crotch or thigh restraint work together to control ride-up.
- Recheck after changes and replace the unit if correct fit cannot be achieved.

Lesson 4 of 8
Inflation Readiness and Backup Controls
What you will learn
Inspect the accessible evidence of an inflatable lifejacket's readiness and separate pre-use checks, wearer controls, rearming and competent servicing.
Inflatable lifejackets depend on several components working together. Check the cover, straps, buckles, cylinder connection and corrosion, firing mechanism or indicator, manual handle, oral tube, dated items and service record against the exact model instructions.
The MCA identifies straps, buckles, outer cover, harness stitching, bladder abrasion evidence, gas-cylinder corrosion and cylinder tightness as important inspection points. RYA guidance adds dated firing parts and lights and notes that a loose screw-in cylinder is a common failure cause. These checks find visible or accessible problems; they do not prove hidden bladder integrity.
Automatic units may use water-activated or hydrostatic pressure-activated mechanisms, while manual inflation requires the wearer to pull the control. The oral tube is provided for topping up or backup inflation. Crew need to know the fitted mechanism and controls before an emergency, but classroom text cannot teach the force, sequence or model-specific handling.
Owner checks, post-inflation rearming and approved servicing are different tasks. Use the exact compatible components and packing sequence. An unexpected indicator, loose or corroded cylinder, damaged webbing or uncertain service state is a reason to withdraw and label the unit, not to improvise a repair aboard.
Worked example
A pre-departure check finds one inflatable lifejacket with an unexpected firing-head indicator and another with a visibly corroded screw-in cylinder. Two spare units are available.
- 1Do not debate which suspect unit is probably good enough; mark both out of service and keep them out of the ready pool.
- 2Issue and fit the known-ready spares to the named wearers.
- 3Record each fault against the unit and follow the exact manufacturer or approved-service route, including compatible replacement parts and repacking where authorised.
Sense check: The departure check has created an operational replacement and an accountable fault route; it has not converted the crew into service technicians.
| Evidence | What it supports | What it cannot prove |
|---|---|---|
| Cover, webbing, buckle and stitching | No visible cut, abrasion, contamination or fastening fault | Hidden bladder integrity or deployment |
| Cylinder connection and corrosion check | The correct visible cylinder appears secure and undamaged | Gas mass, hidden damage or service approval |
| Firing indicator and dated parts | The accessible status matches the model instructions | That every internal part will operate in water |
| Service and rearm record | Required actions were recorded for this serialised unit | That a later fault or misuse has not occurred |
Separate check, withdrawal and return
A jacket accidentally inflates while the crew is preparing the boat and is quickly deflated.
1. Withdraw
Remove it from the ready pool and issue a spare rather than folding it back into service.
2. Identify state
Record the inflation and use the exact model instructions to identify affected cylinder, firing, light, bladder and packing actions.
3. Authorise return
Return it only after the manufacturer or approved-service process has been completed and recorded.
Sense check: Deflation changes the shape, not the fact that gas and activation components have been used.
Common mistake or limitation
- Assuming a green indicator proves the complete inflation system and bladder.
- Mixing cylinders, firing heads, rearm kits or folding instructions between models.
- Treating oral top-up or a tidy repack as restoration of a fired automatic system.
Recap
- Check visible and accessible readiness evidence before use.
- Know the fitted activation and backup controls before an emergency.
- Withdraw faults and keep rearming, servicing and return-to-use model-specific and recorded.

Lesson 5 of 8
Sprayhoods, Lights and Personal Locating Aids
What you will learn
Explain how spray protection, local visibility, alerting and locating aids contribute different functions and integrate compatible equipment with a crew response plan.
Once a person is in the water, keeping an airway clear and making a small target findable are separate problems. A sprayhood, light, retroreflective material, whistle, PLB and AIS MOB device contribute different evidence and limitations.
A sprayhood is intended to reduce spray reaching the face and airway. A light and retroreflective material support local visual detection, while a whistle can provide a short-range sound cue. They do not guarantee a dry airway, continuous visibility or detection in every sea state.
A 406 MHz PLB and an AIS MOB device do not have the same alerting or locating path. Current UK guidance requires applicable UK 406 MHz PLBs used aboard UK vessels or watercraft to be registered and kept current. AIS and other VHF-based MOB systems depend on compatible receivers, identity or installation arrangements and line-of-sight conditions.
Fit any personal device only through the lifejacket manufacturer's compatible arrangement so the aerial, activation, bladder and wearer controls do not obstruct one another. Brief the boat's response and test only through the permitted self-test process; never transmit a live distress alert as a demonstration.
Worked example
A skipper buys a PLB and plans to tuck it inside each inflatable lifejacket. The crew has not checked compatibility, registration, attachment, aerial deployment or what appears on the boat's equipment.
- 1Identify the exact device function and current registration or identity requirement instead of calling every unit an AIS beacon.
- 2Use the lifejacket and device manufacturer guidance to confirm compatible mounting, activation, aerial clearance and effect on inflation.
- 3Register and update the applicable 406 MHz PLB, check dated parts and permitted self-test status, and assign it to a named wearer.
- 4Brief what the crew will see, which radio and search actions continue, and how a false activation is reported through the published process.
Sense check: The personal device now belongs to an alert-and-recovery system rather than being hidden as an unexplained accessory.
| Aid | Contribution | Important limitation |
|---|---|---|
| Sprayhood | Reduces spray exposure around face and airway | Does not guarantee airway clearance or replace correct lifejacket fit |
| Light + retroreflective material | Supports visual recognition and homing in darkness | Range and visibility depend on aspect, sea state, power and search geometry |
| Whistle | Short-range audible cue when voice is difficult | Does not raise a long-range distress alert |
| 406 MHz PLB | Satellite distress alert and location support with registered identity | Must be correctly registered, positioned and activated; it does not narrate every change |
| AIS MOB / VHF locating device | Local alerting or locating to compatible receivers | Not a universal worldwide alert and not equivalent to every PLB function |
Build complementary findability
A night wearer has a light, retroreflective material and an AIS MOB device, so another crew member says a sprayhood and PLB registration no longer matter.
1. Separate functions
List airway protection, visual detection, local electronic locating and long-range distress alerting independently.
2. Check compatibility
Confirm each fitted item, its dates and its relationship to lifejacket inflation and wearer access.
3. Brief response
Rehearse the boat's alarm, lookout, radio and recovery actions without assuming one device closes the rest.
Sense check: Complementary aids reduce different gaps; they are not substitutes selected by quantity.
Common mistake or limitation
- Calling every personal device a PLB or assuming AIS transmission automatically alerts the same rescue chain.
- Mounting a device where it obstructs inflation, aerial deployment, the manual control or the wearer.
- Treating a beacon as a replacement for correct fit, a light, radio updates, lookout or person-capable recovery.
Recap
- Spray protection, visual aids and electronic locating solve different parts of findability.
- Keep registration, compatibility, attachment, dated parts and crew response current.
- No personal device guarantees detection, rescue or a complete situation report.

Lesson 6 of 8
Harness, Tether and Recovery Boundaries
What you will learn
Separate lifejacket flotation, integrated-harness restraint, tether attachment, lifting points and the vessel's person-from-water recovery system.
The safest recovery is often the one made unnecessary by preventing the fall. An integrated harness and safety line can help keep a wearer aboard when correctly specified and attached, but flotation, restraint and lifting remain different equipment functions.
RYA guidance says an integrated lifejacket harness should meet the harness standard as well as the lifejacket standard, and a safety line should connect that harness to suitable, maintained strong points or jackstays. Guardrails are not intended for harness loads. Line length and attachment position should reduce the chance of going over the side rather than merely keep the person connected after a fall.
A crotch strap controls ride-up. A harness attachment connects a safety line. A marked lifting becket or approved recovery attachment may support a specific recovery method. They are not interchangeable because they look strong. Use the exact lifejacket, harness, tether and recovery-equipment instructions and do not improvise a hoist from webbing or the inflated chamber.
The LimbItless and Copious investigations show the wider boundary: even flotation that inflates, and even a suitable lifejacket, do not guarantee timely recovery of a person unable to assist. The vessel needs equipment, roles and practice capable of its freeboard, crew, conditions and an incapacitated casualty.
Worked example
During a briefing, a crew member proposes clipping a tether to the lifejacket's crotch strap and later using the same strap to winch an unconscious casualty aboard.
- 1Stop the plan and identify the labelled, instructed function of each component on the exact unit.
- 2Connect only an approved tether to the certified harness attachment and suitable vessel strong point under the boat plan.
- 3Use the vessel's practiced person-from-water equipment and the lifejacket's instructed recovery attachment, if one exists and the plan permits it.
- 4Rehearse the case where the casualty cannot help, keeping propeller, freeboard, impact and near-horizontal recovery considerations within recognised training.
Sense check: The crew has not converted visible webbing into an assumed fall-arrest or lifting system.
| Part | Primary job | Not automatically authorised |
|---|---|---|
| Lifejacket chamber | Flotation and airway-supporting orientation | Hoisting or towing the wearer |
| Crotch/thigh strap | Control ride-up and keep buoyancy positioned | Use as a lifting sling or tether point |
| Integrated harness attachment | Connect an approved safety line to prevent or limit a fall | Any improvised deck attachment or recovery hoist |
| Lifting becket / recovery attachment | The model-specific instructed recovery function | A universal method for every casualty and vessel |
| Recovery equipment | Return a person from water under the vessel plan | Success without trained crew, access and an incapacitated-person method |
Audit the complete recovery path
A yacht carries fitted lifejackets and tethers but the crew has never brought an unresponsive training dummy from water level to the deck edge.
1. Prevent
Check attachment points, jackstay geometry, line length and task controls intended to keep the person aboard.
2. Locate and connect
Identify the actual recovery equipment and the permitted casualty attachment or lifting arrangement.
3. Recover and hand over
Practice with recognised instruction for a person unable to assist, then brief first-aid and Coastguard communication roles.
Sense check: Carrying a tether and lifejacket is not evidence that the crew can complete the final metre of recovery.
Common mistake or limitation
- Clipping a safety line to guardrails, an unverified fitting or a lifejacket part not approved as a harness point.
- Using a crotch strap, bladder or visible loop as a hoist point without the exact instructions.
- Practicing only with an alert, mobile person who can climb and calling the recovery plan complete.
Recap
- Flotation, fall prevention, tether connection and lifting are distinct functions.
- Use certified, maintained and instructed attachment systems.
- A lifejacket buys flotation time; the vessel still needs a person-capable recovery plan.

Lesson 7 of 8
Servicing and Care
What you will learn
Separate pre-use inspection, post-use care, rearming, approved servicing and return-to-use records for a serialised lifejacket.
Lifejackets are maintained systems, not fit-and-forget clothing. Salt, water, UV, abrasion, contamination, loose or corroded cylinders, expired components, accidental inflation and poor storage can quietly remove readiness.
A pre-use or periodic owner check looks for the accessible evidence specified by the manufacturer. Post-use care removes salt or contamination only through the permitted method, dries the unit correctly and stores it accessible and protected. Neither task replaces competent servicing at the stated interval.
After any inflation, use the exact model's inspection, compatible rearm kit and repacking instructions or an approved service route. A used cylinder, firing element or activated light cannot be treated as ready because the bladder has been deflated. Never generalise one brand's fold, part or interval to another.
Record the unit identity, date, finding, action, replacement components where applicable, service provider and return-to-use decision. A label or spreadsheet is not maintenance by itself, but it prevents a fault, overdue service or withdrawn unit from disappearing back into the ready pool.
Worked example
After a rough passage, three jackets are damp and salty, one light is beyond its marked date and one cylinder has worked loose. The next crew arrives in the morning.
- 1Identify and label each unit; separate the loose-cylinder and dated-light faults from equipment that only needs permitted care.
- 2Issue known-ready replacements for any unit whose readiness cannot be restored through the authorised pre-use process.
- 3Clean, dry, repair, rearm or service each item only through its exact instructions and authorised scope.
- 4Record what returned to service, what remains withdrawn and what the morning crew will actually receive.
Sense check: The clean-looking and fault-free units are not merged into one anonymous pile, and the arriving crew does not inherit an undocumented guess.
| State | Required decision | Do not substitute |
|---|---|---|
| Before use | Complete the model-led accessible inspection and confirm service status | Appearance or purchase date |
| Wet / salty / contaminated | Use the permitted cleaning and drying process before protected storage | Seal it wet in a locker |
| Inflated / fired | Withdraw, inspect, replace exact components and repack or service as instructed | Deflate and fold by memory |
| Fault or uncertainty | Label, record, replace operationally and route to competent service | Leave it in the ready pool for someone else |
| Returned to use | Record completed action and confirm the complete ready state | A verbal assurance with no unit identity |
Use a three-state equipment ledger
The boat currently labels lifejackets only as ‘on board’ or ‘missing’. A fault can therefore remain physically aboard while being counted as available.
1. Ready
Record the identified unit whose check and service state support issue to a wearer.
2. Withdrawn
Physically separate and label faults, used units and uncertain status so they cannot be issued accidentally.
3. Returned
Record the authorised work and completed readiness check before changing the state back to ready.
Sense check: Inventory counts location; a readiness ledger counts what can actually be issued.
Common mistake or limitation
- Applying a universal service interval instead of the exact manufacturer and operational requirement.
- Storing damp or contaminated equipment because the cover looks closed and protected.
- Returning an inflated, faulty or overdue unit to the ready pool after an undocumented quick fix.
Recap
- Inspection, care, rearming and servicing are related but distinct tasks.
- Use exact components, instructions and competent service rather than cross-model memory.
- A unit returns to service only after the action and ready state are confirmed and recorded.

Lesson 8 of 8
Wear, Recheck and Respond to Change
What you will learn
Turn equipment ownership into a clear aboard wearing, recheck, withdrawal and recovery policy that responds to changing people, clothing, conditions and faults.
The strongest lifejacket is ineffective if it is not worn at the point of sudden immersion. A calm boat policy makes the decision before workload, darkness, weather or an emergency makes donning and fitting harder.
RYA guidance recommends wearing a lifejacket, buoyancy aid or impact vest unless you are certain it is not needed. The exact vessel policy should account for activity, operating area, visibility, weather, deck exposure, individual needs and applicable requirements. It should say who wears what and when, not rely on a last-minute call of ‘put them on if it gets rough’.
Recheck after a material change: a new wearer, added or removed layers, unit swap, inflation, heavy spray, contamination, snag, impact, unexpected indicator, overdue service evidence or added personal device. Stop the exposed task when the current unit is not known ready and issue a suitable replacement before continuing.
The policy closes with recovery. Identify how the alarm is raised, how the person remains visible, how propulsion and approach hazards are controlled, how someone unable to assist is recovered, and how the Coastguard and first-aid roles are assigned. A lifejacket provides time and support; it is not the final step.
Worked example
A four-person crew leaves in daylight. At dusk, rain increases and a guest adds a bulky jacket, while another person's lifejacket snags hard on a fitting and shows damaged webbing.
- 1Apply the pre-briefed dusk and exposed-deck wearing policy before people move on deck.
- 2Refit the guest over the new layers and repeat the complete buddy check.
- 3Withdraw the damaged unit, issue and fit a ready replacement, and record the fault rather than allowing the task to continue unprotected.
- 4Restate the night alarm, lookout, location and recovery roles so the equipment change does not leave the response plan stale.
Sense check: The policy has converted three changes into controlled actions without waiting for an incident to reveal them.
| Change | Immediate control | Next evidence |
|---|---|---|
| Night, weather or deck exposure increases | Apply the pre-briefed wearing and clipping policy before exposure | Named wearer, fit, controls and safe attachment plan |
| Layers or wearer change | Stop and refit or reselect | Model scope and complete buddy check |
| Fault, impact, snag or unexpected indicator | Withdraw and issue a known-ready replacement | Recorded manufacturer or approved-service route |
| Person enters the water | Raise alarm, retain sight and execute the practiced vessel plan | Current position, people, casualty and person-capable recovery route |
Write a decision, not a slogan
The current safety brief says only, ‘Use lifejackets in bad weather.’
1. Set triggers
Name the visibility, deck-work, weather, vessel and individual conditions that start the policy.
2. Set evidence
Allocate exact units and require the fit, readiness and accessory checks relevant to the task.
3. Set failure action
State when work stops, equipment is withdrawn, a replacement is issued and the recovery brief is updated.
Sense check: A useful policy lets a crew member act without first debating what ‘bad’ means during the hazard.
Common mistake or limitation
- Waiting until the deck is wet, dark or moving heavily before donning and fitting equipment.
- Allowing an exposed task to continue while a suspect unit is being discussed or repaired.
- Ending the policy at ‘wear a lifejacket’ without alerting, visibility and recovery for an incapacitated person.
Recap
- Make the wearing decision before the hazard, not during it.
- Every material change can reopen selection, fit, readiness or crew-response checks.
- Complete the chain with person-capable recovery and communication.
