Safety at sea is never an option, but an absolute necessity for any sailor, whether novice or experienced. At the heart of this essential safety equipment is the life jacket, a real life insurance policy during sea trips. Every year in France, many nautical accidents could have been avoided by simply wearing a suitable vest. Between inflatable and foam models, the different buoyancy standards and the specificities associated with each nautical activity, the choice can quickly become complex. French regulations also require the presence of a life jacket for each person on board, with precise technical characteristics depending on the navigation zone. So how do you find your way around this plethora of offers and identify the model that will be perfect for your nautical practice? Between comfort, optimal safety and compliance with standards, this article guides you step by step in the crucial choice of your life jacket, this discreet but potentially vital companion in all your maritime adventures.

Why wear a life jacket at sea?

A legal obligation

Wearing a life jacket is not just a recommendation, but a strict legal requirement in many circumstances. Division 240, which regulates the safety of recreational vessels in France, clearly states that each boat must have individual buoyancy equipment for each person on board. More precisely, for ships sailing beyond 2 miles from a shelter, this equipment must meet specific buoyancy standards (100 newtons minimum). For marine professionals, the requirements are even more stringent, with equipment adapted to sometimes extreme working conditions. Penalties for non-compliance can be severe, ranging from fines to criminal proceedings in the event of an accident. These regulations are regularly evolving towards greater rigor, testifying to the capital importance given to this equipment by the maritime authorities.

Vital protection in the event of a fall into the water

Falling into the water is one of the most dangerous dangers in navigation, even for experienced swimmers. A properly fitted life jacket can literally mean the difference between life and death. By keeping the airways out of the water, even in the event of loss of consciousness, it prevents drowning and significantly extends survival time. The statistics speak for themselves: more than 75% of victims of fatal accidents at sea did not wear life jackets. In cold water, thermal shock can cause hydrocussion or a rapid loss of motor skills, making swimming impossible even for the most athletic. The vest then guarantees precious buoyancy, allowing you to maintain your energy and wait for help. Its bright color and reflective strips also increase visibility, greatly facilitating search and rescue operations, which are especially crucial during adverse weather conditions or at night.

Increased risks depending on the weather and nautical activity

Weather conditions and the type of nautical activity practiced directly influence the level of risk at sea. In rough seas, with waves that can exceed several meters, even seasoned sailors can get out of balance and go overboard. Strong winds amplify this danger by making maneuvers more difficult and creating a chaotic sea. Risky activities such as big game fishing, where the practitioner may find himself in precarious balance, or sport sailing, which involves rapid movements on deck, require particular vigilance and perfectly adapted equipment. Navigation at night also presents additional challenges with reduced visibility and obstacles that are more difficult to detect. For each of these situations, the type of vest recommended differs, as does its buoyancy level. An experienced navigator will know how to adapt his equipment according to these parameters, sometimes preferring a vest that is more restrictive but offers greater safety when conditions require it.

The different types of life jackets

inflatable life jacket

Automatic vs manual

Inflatable life jackets fall into two main categories depending on how they are triggered. The automatic model inflates instantly upon contact with water thanks to a water-soluble tablet that releases a striker, thus activating the CO2 cartridge. This system offers optimal protection, especially in the event of an unexpected fall or loss of consciousness. The manual model, on the other hand, requires active intervention by the wearer who must pull on a tab to trigger inflation. All inflatable vests also have a complementary mouth inflation tube to complete the inflation if necessary. The choice between these two systems depends mainly on your activity: solitary navigators will prefer automatic triggering, while practitioners of activities where water is frequent (such as jet skiing) may prefer manual triggering to avoid untimely inflation.

Advantages and disadvantages

Inflatable vests have a number of advantages that explain their increasing popularity. Their minimal size and lightness make them comfortable equipment, particularly appreciated for long outings. Their ergonomic design allows almost total freedom of movement, essential for technical maneuvers in navigation. Once inflated, they generally offer superior buoyancy (150N to 275N) than foam models, as well as excellent head support above water.

However, these benefits come with a few notable drawbacks. Their effectiveness depends entirely on the proper functioning of the inflation system, which involves regular and rigorous maintenance. The acquisition cost is higher, plus the periodic replacement of the CO2 cartridges and the trigger mechanism. If the automatic system fails or manual activation is forgotten, the vest becomes useless. Some models may also be less comfortable once inflated, limiting the mobility of the castaway. Finally, the inflation time, although very short, can represent an additional risk in certain extreme situations.

Foam vest (permanent buoyancy)

For whom?

Life jackets with permanent buoyancy made of foam are aimed at a varied audience, meeting specific needs. They are the preferred choice for children, whose safety cannot be left to a potentially faulty mechanical device. Beginners in boating will also find it a reassuring solution, immediately operational without prior manipulation. Practitioners of dynamic water sports such as water skiing, wakeboarding or jet skiing prefer these models for their impact resistance and their ability to withstand repeated shocks. Sailing schools and nautical centers are massively adopting them to equip their trainees, appreciating their reliability and ease of use. Finally, navigators in difficult or cold waters, where a failure in the inflation system could have dramatic consequences, often opt for these models with guaranteed buoyancy. Their permanent visibility, usually in bright colors, is an additional asset for rescue operations.

Durability and maintenance

Foam vests stand out for their exceptional longevity when properly maintained. Unlike inflatable models, they do not have a mechanism that is likely to deteriorate over time, which makes them particularly reliable over time. Maintaining them is also much easier: regular rinsing with fresh water after use at sea is generally sufficient to maintain their properties. For more thorough cleaning, soapy water is recommended, absolutely avoiding aggressive detergents that could damage the foam or the seams.

Drying should be done in the open air, away from direct sunlight, which can damage synthetic materials in the long term. A regular visual check makes it possible to detect any tears, permanent compression of the foam or defects in the straps and buckles. Manufacturers generally recommend replacement every 7 to 10 years, but a well-maintained vest can sometimes exceed this theoretical lifespan. This ease of maintenance and durability partly compensate for the inconvenience of their bulkiness, making foam vests a particularly profitable investment in the long term.

Specific vests for children, animals, water sports

Safety at sea is not only for adults who practice traditional navigation. Children require equipment specifically designed for their morphology and weight, with adapted characteristics: ergonomic collar to effectively support the head, crotch strap to prevent the vest from rising, back recovery handle facilitating retrieval, and secure closure systems that the child cannot open alone. Bright colors and reflective elements enhance their visibility.

Our faithful four-legged friends also deserve appropriate protection. Dog vests have a specific cut that respects their anatomy, with distributed buoyancy to keep the animal in a natural horizontal swimming position. Heavy-duty recovery handles and safety lanyard ties generally complement this equipment.

Dynamic water sports (water skiing, wakeboarding, kitesurfing, kayaking, etc.) require vests that combine safety and freedom of movement. These models offer a slim fit, flexible materials, and are designed to withstand impacts. They generally prefer moderate buoyancy (50N to 100N) distributed strategically so as not to hamper movements, while sometimes integrating shock protections for certain risky sports.

How do I choose the right life jacket?

Depending on the navigation program

Choosing the right life jacket depends fundamentally on your sailing program. For coastal navigation (up to 6 miles from a shelter), a 100N to 150N vest is generally a good compromise between safety and comfort. Inflatable models are particularly suitable, offering considerable freedom of movement while ensuring sufficient protection against moderate risks.

Offshore navigation, which takes you considerably away from the coast, involves increased risks and potentially very long emergency response times. In this case, it is imperative to choose high buoyancy vests (275N), which guarantee effective turning even with heavy clothing or in rough seas. Models equipped with an anti-spray hood, an automatically triggered lamp and an integrated emergency beacon offer optimal safety in these demanding conditions.

For river navigation, the constraints differ significantly. Currents, submerged obstacles and shallow depths represent the main dangers. A 100N vest, often with permanent buoyancy for immediate action, is generally the recommended equipment. Since visibility is essential in these environments where boats can be numerous, opt for bright colors and quality reflective strips.

Depending on the weight and height of the user

The effectiveness of a life jacket depends closely on its morphological adaptation to the wearer. Incorrectly sized equipment can not only be uncomfortable, but especially dangerous in emergency situations. Manufacturers generally offer accurate correspondence tables between weight, chest, and recommended size.

For adults, the standard categories generally fall into the following categories:

• XS: less than 40 kg, chest less than 85 cm
• S: 40-60 kg, chest 85-95 cm
• M: 60-70 kg, chest 95-105 cm
• L: 70-90 kg, chest 105-115 cm
• XL: 90-110 kg, chest 115-125 cm
• XXL: over 110 kg, chest greater than 125 cm

These indications must be adapted according to the body size: a person who is tall but light will prefer a vest that is bigger than what their weight suggests. The fit is crucial: the vest should not go up past the chin when pulled up, and the straps should allow for a firm fit without impeding breathing or movement. For inflatable models, check that the air chamber, once deployed, does not exert excessive pressure on the neck or neck. Some manufacturers now offer models specifically designed for female morphologies, taking into account anatomical differences for optimized comfort and safety.

Depending on the buoyancy level required (50N, 100N, 150N, 275N)

The buoyancy of a vest, expressed in newtons (N), determines its ability to keep an individual on the surface. This fundamental criterion varies according to several factors and should be selected with particular care.

50N equipment, sometimes called “buoyancy aids”, is only suitable for experienced swimmers operating in calm waters and near banks or shorelines. They do not guarantee the turn over of an unconscious person and are generally reserved for supervised nautical activities such as canoeing, rowing or stand-up paddle boarding.

100N vests represent the legal minimum for coastal navigation. They ensure good support on the surface and can, under favorable conditions, turn an unconscious person upside down to position their airways out of the water. They are a good compromise for boating in protected areas or in good weather.

The 150N category offers significantly greater safety, guaranteeing rollover in most situations, even with lightweight clothing. These models are recommended for coastal navigation in variable conditions or for solitary sailors who want an increased margin of safety.

275N vests represent the highest level of protection available. Specifically designed for offshore navigation or extreme conditions, they ensure effective turning even with heavy clothing, in rough seas or in case of loss of consciousness. Their large volume once deployed can be restrictive, but offers maximum buoyancy, which is particularly valuable when the wait for help can be prolonged.

For optimal safety, the rule is to choose a level of buoyancy higher than the minimum legal requirements corresponding to your navigation area, taking into account your usual equipment (heavy clothing, boots) and the weather conditions that you are likely to encounter.

Standards and certifications to know (ISO 12402, CE...)

Compliance with international standards is an essential indicator of the reliability and effectiveness of a life jacket. The ISO 12402 standard, a global reference in this field, is divided into several parts corresponding to the different levels of buoyancy:

• ISO 12402-5 for 50N buoyancy aids
• ISO 12402-4 for 100N vests
• ISO 12402-3 for 150N vests
• ISO 12402-2 for 275N vests

The CE marking, mandatory on all equipment sold in the European Union, attests that the product meets the essential safety requirements established by European directives. It must be visible and indelible on each vest.

Other certifications can provide additional guarantees. SOLAS (Safety Of Life At Sea) certification, which is particularly demanding, is required for vests equipping commercial vessels. The MED (Marine Equipment Directive) certification also ensures a higher level of quality, with particularly rigorous tests.

Vests intended for professional use must often meet specific sectoral standards, such as the standards established by national maritime authorities for professional fishermen. Some manufacturers also have their products certified by independent organizations such as Bureau Veritas or Lloyd's Register, thus offering an additional guarantee.

These standards evolve regularly to incorporate technological innovations and feedback. It is therefore recommended to check that your equipment complies with the most recent versions. The date of manufacture, which must be indicated, makes it possible to identify the generation of applicable standards.

Life jackets: the criteria to check before buying

Trigger system

The trigger system represents the technological heart of inflatable vests and deserves particular attention when choosing. Several technologies coexist, each with its own specificities.

Hydrostatic triggering, a high-end solution, is activated only when the vest is immersed to a depth of about 10 cm. This technology considerably limits the risk of untimely triggering due to rain or spray, while guaranteeing rapid activation in the event of a real fall. Hydrostatic sensors, such as those used by Hammar or UML, are generally more expensive but offer greater reliability.

Triggering by water-soluble pellet, more common, is based on a tablet that dissolves in contact with water, releasing a striker that perforates the CO2 cartridge. While this system is effective in most situations, it can sometimes be triggered in case of high ambient humidity or significant spray. The quality of the tablet and its regular replacement (generally annual) are decisive for its reliability.

Beyond the mechanism itself, carefully consider the build quality of the housing containing the striker, its accessibility for replacements, and the availability of refills. A well-designed system should allow a simple visual verification of the state of armament, generally materialized by a visible colored indicator without complex manipulation.

Integrated safety harness

The integration of a safety harness into the life jacket is a major development, which is particularly valuable for sailing with a small crew or alone. This device makes it possible to be securely attached to the boat via a safety lanyard, thus preventing the risk of separation in the event of a fall into the water, a particularly critical situation when the ship continues on its way.

A quality harness must meet the EN ISO 12401 standard and support a load of at least 1 ton. Take a close look at the design of the straps, which should ideally form a Y or an X on the torso to effectively distribute forces in the event of a sudden impact. The attachment point, generally located in the center of the chest, should be easily accessible but impossible to unhook unintentionally. It should also be designed so as not to damage the vest under high tension.

The compatibility with various lanyards deserves your attention: possibility of using double-branch lanyards, presence of a recovery ring that facilitates hoisting on board, compatibility with quick release systems if necessary. Some models even incorporate an accessible line cutter, the ultimate solution if the lanyard becomes dangerous (for example by getting tangled in the propeller).

The comfort of the harness is essential: the straps must be wide enough to distribute the pressure, ideally padded at the shoulder level, and not create friction points even during repetitive movements. Adjustments should allow for precise tightening without compromising breathing or mobility. These criteria take on increased importance during prolonged navigation, where discomfort can lead to neglecting the wearing of the device, thus cancelling its safety benefit.

Visibility and reflective strips

In a situation of distress at sea, being seen quickly can make all the difference. The visibility of your life jacket is therefore a fundamental selection criterion, which is often underestimated by boaters.

The color of the vest represents the first factor of identification during the day. Fluorescent colors, especially bright orange or lemon yellow, offer optimal visibility even on an overcast day or in case of heavy seas. They contrast effectively with the marine surface and stand out at considerable distances. Some manufacturers are developing high visibility materials, integrating specific pigments that amplify the reflection of natural light.

Reflective strips become crucial in low light conditions or at night. Their quality, surface area and strategic positioning determine the effectiveness of tracking by projectors or light sources. The SOLAS standard defines minimum requirements for these elements: 400 cm² of retro-reflective material, distributed to ensure 360° visibility. The best belts maintain their properties even after repeated immersions in salt water and are UV-resistant without significantly degrading their performance.

Additional signaling equipment represents a significant evolution in this field: lamp with automatic immersion activation, powerful whistle, integrated strobe systems. High-end models sometimes incorporate a personal AIS beacon that automatically transmits the position of the castaway to nearby equipped vessels.

Comfort and freedom of movement

A life jacket only fulfills its full function if it is actually worn. Comfort therefore represents a decisive criterion in the choice of this safety equipment, directly linked to the regularity of its use.

The anatomical cut is the first factor of comfort. Recent models benefit from ergonomic designs adapted to different body types, with specific cuts for men and women. The areas in contact with the neck, which are particularly sensitive, deserve special attention: look for collars that are soft, padded and do not cause friction even during repetitive movements. The balance of the vest is also crucial to avoid localized pressure points that quickly become uncomfortable over time.

The adjustment systems largely determine the adaptation of the vest to your body type. Choose models that offer several adjustment points (shoulders, sides, crotch for some models) with straps that are wide enough not to create discomfort. The buckles should allow for a precise fit while remaining easy to handle, even with cold hands or gloves. Marine grade zippers complemented by safety clips generally offer the best compromise between ease of use and safety.

Freedom of movement remains essential for maneuvering on board. Modern inflatable vests, especially hammock or Y models, minimize restrictions by intelligently distributing their components. For activities requiring great mobility (sports maneuvers, active fishing), look for cut-outs that allow maximum arm range without armpit friction. The weight of the vest also affects comfort: recent models, using lightweight technical materials and miniaturized components, can drop below 700 grams while maintaining their safety properties.

Maintenance and inspection of your life jacket

Frequency of checks

A life jacket requires constant supervision to ensure that it functions properly the day you actually need it. The frequency of checks must adapt to the intensity of your nautical practice and to the conditions of use.

Visual inspection before each ride is the first line of defense against failures. It makes it possible to quickly detect obvious problems: tears, undone seams, frayed straps or damaged buckles. For inflatable vests, always check the trigger system status indicator and the CO2 cartridge charge level. This inspection only takes a minute but can be decisive.

A thorough monthly check is recommended for regular use. It includes a detailed examination of the tensions under tension, the straps in their attachment points, and the proper functioning of the adjustment systems. For inflatable vests, check the airtightness of the air chamber by inflating the mouth followed by an observation period of 12 hours to detect possible leaks. This check also makes it possible to verify the absence of mold or moisture stains inside the envelope.

An annual professional inspection completes this maintenance system. Ideally carried out by the manufacturer or an authorized dealer, it includes a complete dismantling of the trigger mechanism, the replacement of the perishable elements (water-soluble tablet, O-ring), and a thorough check of the integrity of the air chamber. This control is generally attested by a dated certificate that may be required in the event of an inspection by the maritime authorities.

For Oria Marine users, the monitoring of life jacket control dates is directly integrated into our online platform. You therefore receive an alert when a check is approaching and can follow all your security equipment at a glance.

Storage and precautions

Storage conditions have a direct impact on the longevity and reliability of your life jacket. Inadequate storage can silently compromise its capabilities, potentially causing it to fail at a critical moment.

Choose a dry and ventilated environment, away from direct sunlight and extreme temperatures. UV gradually degrades synthetic materials, while excessive heat can alter the integrity of the air chambers and the functioning of the trigger mechanisms. Hanging storage on a dedicated hanger is the ideal solution, avoiding permanent creases that weaken the seams and inflation areas. If this configuration is not possible, store the vest flat, without heavy objects placed on it that could compress the foam or damage the components of the inflatable models.

Humidity is the main enemy of this equipment. After each use at sea, a thorough rinse with fresh water is required to eliminate salt, which is particularly corrosive to metal parts such as CO2 cartridges or trigger mechanisms. Drying should be natural and complete before storage, avoiding direct heat sources that can deform some components. The use of a dehumidifier in the storage room is a useful additional precaution for particularly humid regions.

Protection against rodents and insects should not be overlooked, especially for seasonal storage. These unwanted visitors can cause irreversible damage to straps and tubes. A breathable storage bag, specifically designed for vests, provides effective protection while allowing the evacuation of residual moisture. Some high-end models offer antibacterial covers that also limit the development of mold.

When should you replace your vest?

Even when properly maintained, a life jacket does not last forever. Recognizing the signs of aging and anticipating replacement before a critical failure is an integral part of a responsible safety approach.

The average lifespan of a vest varies considerably depending on its technology and conditions of use. Manufacturers generally recommend replacement every 5 to 10 years for inflatable models and every 7 to 12 years for foam vests. However, this theoretical estimate must be adjusted according to the intensity of use and the quality of storage.

There are several physical signs that clearly indicate that a replacement is becoming necessary. For all types of vests, significant discolorations, especially reflective strips, indicate excessive UV exposure and probable material degradation. Frayed seams, even partially, significantly compromise structural strength and are an immediate reason for replacement. Stiffened or cracked straps lose their tensile strength and no longer guarantee effective support.

For foam vests, permanent deformation or compression of the floating panels directly reduces buoyancy. A simple test consists in comparing the current weight of the vest with that indicated in the original specifications: a noticeable difference suggests foam degradation. For inflatable models, the difficulties in maintaining pressure after oral inflation (loss greater than 10% in 12 hours) indicate increasing porosity of the air chamber and require replacement.

The accidental or effective triggering of the inflation mechanism also warrants a thorough inspection and often a replacement of the vest. The stresses experienced during automatic inflation can weaken certain components, compromising their reliability for later use. Some manufacturers now offer reconditioning programs after triggering, but this solution does not always offer the same guarantees as new equipment.

Common mistakes to avoid when choosing a vest

Buy only according to price

The most common mistake is to make price the main selection criterion. This purely economic approach can be dangerous because it neglects the fundamental aspects of safety and suitability for the intended use. Excessively cheap entry-level vests often use lower quality materials and less reliable trigger systems, compromising their effectiveness in critical situations.

The reasonable approach is to precisely define your budget according to the frequency of use and the level of risk of your nautical practice. Then choose the best possible quality in this price range, paying particular attention to critical components such as the trigger system, the quality of the seams and the robustness of the straps. Vests from recognized brands generally benefit from better quality control and a more developed maintenance network, often justifying a slightly higher investment.

Neglecting the adjustment

A vest that is perfectly adapted to your body shape can save your life, while a poorly adjusted model can be dangerously ineffective or even counterproductive. However, this evidence is frequently overlooked when buying, especially when shopping online without trying it on.

The consequences of a poor fit are multiple and potentially serious: a vest that is too large can rise beyond the face during immersion, hindering breathing instead of facilitating it; too tight, it limits movements and can cause discomfort such that it discourages its wearing. For inflatable vests, incorrect positioning on the torso can compromise automatic turning or put dangerous pressure on the neck and neck during deployment.

Take the time to try out several sizes and models, reproducing the movements typical of your nautical activity: torso rotation, raising your arms, sitting for a long time. The ideal vest should allow a normal amplitude without compression points or armpit friction. Once adjusted, perform the “lift test”: ask someone to pull the vest up by the shoulders; if it goes up past the chin, the fit is inadequate. For children, the presence of a properly adjusted crotch strap is essential to prevent the vest from rising above the head.

Forget the specifics of the activity

Each nautical activity has specific constraints and risks that directly determine the appropriate type of vest. Neglecting these particularities often leads to unsuitable and potentially dangerous choices.

For sport sailing and regattas, freedom of movement comes first: a thin inflatable vest, with manual or hydrostatic triggering to avoid untimely activations during spray, is generally the ideal solution. Conversely, for sea fishing where movements are more limited but the risks of falling due to imbalance are higher, an automatic high-buoyancy vest with ergonomic collar offers optimal safety.

Sliding sports such as water skiing or wakeboarding require specific vests with permanent buoyancy, designed to withstand repeated impacts and strong accelerations. For sea kayaking, the presence of a collar adapted to prolonged sitting and compatible with paddle movements is a determining criterion.

Winter or cold water navigation imposes additional requirements: reinforced buoyancy to compensate for the weight of clothing, greater turning capacity, and ideally a design compatible with thermal insulation equipment. In contrast, sailing in tropical climates benefits from breathable and anti-bacterial materials that limit the discomfort caused by prolonged perspiration.

FAQS

Is a life jacket mandatory on a pleasure boat?

Yes, French regulations require the presence of individual buoyancy equipment (EIF) for each person on board a pleasure vessel. Division 240, which regulates the safety of recreational vessels, specifies the technical characteristics required according to the distance from shore:

• Navigation up to 2 miles from a shelter: buoyancy aid of at least 50N (or combined worn with this buoyancy)
• Navigation between 2 and 6 miles from a shelter: vest of at least 100N
• Sailing beyond 6 miles from a shelter: 150N vest minimum

The effective wearing of a vest is mandatory at all times only in certain specific situations: for children under 12 years of age on non-habitable boats, when using beach equipment beyond the 300 meter band, for risky activities such as jet skiing, or at the decision of the captain depending on the conditions. However, even when it is not legally mandatory, wearing a vest is highly recommended, especially for non-swimmers, when sailing alone or in bad weather conditions.

What is the difference between a life jacket and a buoyancy aid?

The distinction between these two types of equipment is based on their ability to turn an unconscious person around to position their airways out of the water.

A life jacket (100N, 150N or 275N) guarantees the wearer to turn over, even unconscious, within a specified period of time. This ability is crucial because it ensures survival even in the event of loss of consciousness as a result of shock, shock, or exhaustion. This equipment also keeps your head above water with a significant freeboard (distance between the mouth and the surface), limiting the risks of inhaling water even in a formed sea.

A buoyancy aid (50N) simply keeps its wearer on the surface but does not guarantee the automatic turning over or keeping the airways out of the water. It is only intended for experienced swimmers who are able to remain actively in a safe position. This equipment, which is generally more compact and less restrictive, is suitable for supervised nautical activities or practiced near the coast, in favorable conditions.

This fundamental distinction explains why regulations impose increasing levels of buoyancy as one moves away from the coast: emergency response times increase, increasing the probability of the castaway exhausting or losing consciousness before being rescued.

What size vest should I choose for a child?

Particular care should be taken when choosing a vest for children, as the consequences of unsuitable equipment can be dramatic. Unlike adults, the selection is based primarily on weight and not on chest size.

The standard categories for children are usually as follows:

• Baby: 3-10 kg (only for specific “baby” models with head support)
• Child XS: 10-15 kg (usually 1-3 years old)
• Children S: 15-20 kg (usually 3-6 years old)
• Child M: 20-30 kg (usually 6-8 years old)
• Child L: 30-40 kg (usually 8-12 years old)

Above 40 kg, adult XS models can generally be suitable, but always check the actual fit. These age indications remain approximate, with the actual weight of the child being the decisive criterion.

Several specific characteristics are essential for children's vests: a solid crotch strap (which prevents the vest from going up), an adapted collar that effectively supports the head, a sturdy back recovery handle, and secure closures that the child cannot open alone. Always choose models with permanent buoyancy for children, as inflatable vests are generally not recommended before 40 kg due to the risks of inappropriate triggering or non-activation by the panicked child.

Trying on is still essential: check that the vest does not rise beyond the chin when pulled up and that the straps are properly adjusted without hampering breathing or movement. A well-chosen vest should be comfortable enough to be accepted without hesitation by the child, an essential condition for it to be actually worn.

How long does a life jacket last?

The lifespan of a life jacket varies considerably depending on its technology, manufacturing quality, and conditions of use and storage.

For inflatable vests, manufacturers usually indicate a lifespan of 5 to 10 years. This estimate concerns the envelope and the air chamber, but the components of the trigger system require more frequent replacement: the CO2 cartridge every 3 years (even if it has not been hit), the water-soluble tablet annually or after each prolonged immersion, the hydrostatic trigger mechanism typically every 5 years. Rigorous maintenance and regular checks can significantly extend this theoretical lifespan.

Permanent foam buoyancy vests have a longer lifespan, generally estimated between 7 and 12 years. Their mechanical simplicity makes them less vulnerable to aging, but the foam can gradually degrade, losing its floating power through compression and exposure to UV. High-quality models, using high-density closed-cell foams, have the best resistance to aging.

Beyond these theoretical estimates, several factors directly influence the effective lifespan: frequency of use, exposure to UV and salt, the quality of rinsing after use, and storage conditions. A vest used extensively in a tropical marine environment will age considerably faster than identical equipment used occasionally in fresh water and properly maintained.

Do you need a different vest for paddleboarding or kayaking?

Yes, activities such as paddle boarding (SUP) or kayaking require buoyancy equipment that is specifically adapted to their particular constraints.

For paddleboarding, a dedicated vest has several essential characteristics: a short cut on the torso freeing up the lower chest to facilitate paddling movements, wide armholes that avoid friction during large paddling movements, and a minimalist design that reduces water retention and weight after immersion. The buoyancy required remains moderate (50N to 70N) because the paddle board itself constitutes a substantial floating support in the event of a fall.

For kayaking, the requirements differ significantly. A suitable vest should offer a high cut compatible with prolonged sitting, completely freeing the lower back to avoid pressure points against the back of the seat. The front pockets, ideally waterproof, allow easy access to safety equipment without leaving their position. The presence of an ergonomic collar that does not hinder rotational movements of the neck is particularly important, as is a fine adjustment allowing a precise adjustment to seasonal technical clothing (light suit in summer, insulation equipment in cold conditions).

For sea or whitewater kayaking, superior buoyancy (70N to 100N) is recommended, as well as lateral reinforcements to protect against impacts with rocks. Advanced models incorporate an extraction harness that facilitates retrieval by a rescuer, particularly useful in case of desalination in difficult waters.

Can you lend your vest to a friend?

Lending a life jacket is possible but requires certain important precautions to ensure the safety of the borrower.

The first consideration concerns morphology: a vest must be perfectly adapted to its wearer to effectively fulfill its function. Carefully check the fit on the borrower, paying particular attention to the shoulder and side straps. For inflatable vests, make sure the chest strap positions the vest correctly to ensure effective rollover in the event of a trip.

If your vest is an inflatable model, it is essential to check the condition of the CO2 cartridge and the trigger system before lending. A partially triggered system or an already pierced cartridge would make the vest completely ineffective without this necessarily being visible to the untrained eye. Clearly explain to the borrower how the mechanism works, especially for manually triggered models that require voluntary action.

Inform the borrower of the specificities and limitations of your equipment: buoyancy level, presence or absence of an integrated harness, compatibility with certain specific nautical activities. A 150N life jacket designed for offshore sailing may be unsuitable or restrictive for a coastal kayak trip, and vice versa.

Also specify maintenance requirements after use, including rinsing with fresh water and thorough drying before storage. This simple precaution significantly extends the life of the equipment and ensures its subsequent correct operation.

Finally, at the regulatory level, be aware that the responsibility of the captain includes verifying the adequacy of the safety equipment on board, including the vests loaned. In the event of an inspection, it is he who is responsible for the conformity and good condition of all the equipment on board.

How do you know if a vest is still up to standard?

Checking the normative conformity of a life jacket is essential to guarantee its effectiveness and legality. Several elements make it possible to assess whether your equipment still meets current standards.

The certification label is the first thing to look at. It must include the CE marking followed by the number of the notified body that carried out the certification, as well as the reference to the applicable ISO standard (generally ISO 12402, followed by the number corresponding to the buoyancy level: -2 for 275N, -3 for 275N, -3 for 150N, -3 for 150N, -4 for 100N, -5 for 50N). Check that this label remains perfectly legible; its erasure or deterioration may constitute a reason for non-compliance during an inspection.

The date of manufacture, which must be indicated on the vest, makes it possible to locate the equipment in relation to regulatory developments. ISO standards are regularly revised (approximately every 5 years), with transition periods during which the old models remain compliant. Beyond this period, a vest may become obsolete even if it seems to be in good condition. This normative obsolescence particularly concerns equipment dating from before 2006, the year of a major overhaul of European standards.

For inflatable vests, carefully inspect the expiration dates of critical components: CO2 cartridge (generally 3 years), water-soluble tablet (1 year), hydrostatic trigger mechanism (5 years). A vest whose components have expired no longer meets standards, even if the inner tube remains intact.

The general condition of the equipment also determines its compliance: any tear or undone stitching, any alteration of the straps or buckles, or any permanent compression of the floating panels constitutes a reason for non-compliance. Reflective strips must maintain their retro-reflective properties to meet regulatory requirements; test them with a powerful lamp in the dark to verify their effectiveness.

In case of doubt, or for professional equipment subject to strict regulatory constraints, a check by a certified professional remains the most reliable solution. Some manufacturers offer verification and recertification services to legally extend the life of your equipment.
