Lifeboat vs. Life Raft: The SOLAS Guide to Maritime Survival Gear Explained
A clear, practical comparison of lifeboats and life rafts, including design, capacity, launching, survival equipment, maintenance, servicing, training, costs and the mistakes that can create danger during an abandon-ship emergency.
When the general alarm sounds, a seafarer does not have time to compare equipment brochures. The correct questions are already answered by the muster list: Where is my station? Which craft am I assigned to? What equipment must I carry? Who is in charge? Which route is safe?
Yet understanding the difference between a lifeboat and a life raft is still important. It helps a new crew member recognise the equipment, understand why different survival craft are carried and avoid dangerous assumptions. A lifeboat and a life raft are both survival craft, but they are not interchangeable. They have different structures, launching methods, capacities, propulsion arrangements, equipment and operating demands.
The most accurate way to think about the comparison is not “Which one is better?” It is “What role does each craft perform in the ship’s approved survival system?” A lifeboat may provide a rigid, powered platform with greater manoeuvrability. A life raft may provide rapid buoyancy and an inflatable sheltered space that can be launched, davit-launched or float free according to its arrangement. Both depend on correct stowage, maintenance, training and timely action.
What does SOLAS require?
The International Maritime Organization states that ships must carry appropriate life-saving appliances under the SOLAS Convention. The International Life-Saving Appliance Code, commonly called the LSA Code, gives more specific technical requirements for manufacture, testing, maintenance and recordkeeping.
The exact number, capacity and type of lifeboats and life rafts varies according to the ship’s size, service, passenger capacity, cargo, voyage and approved safety arrangement. This is why a general internet article cannot tell a particular crew which craft to launch first. The ship’s certificates, plans, muster list and flag-State requirements control.
SOLAS Chapter III covers muster lists and emergency instructions, operating instructions, manning and supervision, survival-craft stowage, launching stations, launching and recovery arrangements, emergency drills, operational readiness, maintenance and onboard training manuals.
Lifeboat
A rigid or approved survival craft designed to carry people away from the ship, normally with steering and propulsion or another approved arrangement, and with survival equipment and provisions.
Life raft
An inflatable or approved rigid survival craft stored compactly and intended to provide buoyancy, shelter and survival equipment after launch or float-free deployment.
Rescue boat
An active craft intended for recovering people from the water and assisting survival craft. It is related to, but not identical with, a lifeboat or life raft.
Launching appliance
A davit, winch, falls, hooks or other approved arrangement used to move a survival craft from its stowed position to the water.
Lifeboat: structure, propulsion and protection
A lifeboat is generally a rigid survival craft. Depending on the ship and approval, it may be open, partially enclosed or enclosed. It may be launched by davit, released by a free-fall arrangement or use another approved system. The design is not universal, so crew must learn the actual boat carried onboard.
Many lifeboats are powered and have a rudder, steering arrangement, engine, fuel, compass, communications and survival provisions. The boat can therefore move away from the ship, manoeuvre in the vicinity, maintain a position more effectively than an unpowered craft and support organised survival while awaiting rescue.
Enclosed or partially enclosed arrangements can provide protection from wind, spray, cold and sun. That protection is valuable, but it does not make the boat invulnerable. Occupants still need to follow instructions, conserve resources, maintain ventilation as designed, use the craft’s equipment correctly and manage seasickness, injuries and exposure.
Life raft: compact, buoyant and highly dependent on servicing
A life raft is commonly stored in a rigid container or valise. When deployed, an inflatable raft expands to create a floating survival space. It normally includes a canopy, painter, sea anchors, lights, rescue lines and survival equipment appropriate to its approved pack and capacity.
The LSA Code requires an approved liferaft to meet specific construction, capacity, buoyancy, stability, canopy and equipment requirements. A liferaft is not simply a large inflatable boat. Its floor, buoyancy chambers, canopy, entrances, sea anchors, painter and survival pack are designed as an integrated survival system.
Some rafts are throw-over types. Others are designed for davit launching. Some arrangements include float-free deployment using a hydrostatic release unit, allowing the container to release as the vessel sinks and the raft to inflate at the surface. The exact arrangement depends on the ship’s approved equipment.
Lifeboat vs life raft: key differences
| Feature | Lifeboat | Life raft |
|---|---|---|
| Basic structure | Usually rigid, with an approved hull and fixed or fitted equipment. | Inflatable or approved alternative construction stored compactly before deployment. |
| Propulsion | Often has an engine and steering arrangement, subject to the boat’s approval. | Normally has no engine; it uses sea anchors, paddles or rescue support as provided. |
| Launching | May use davits, free-fall systems or another approved arrangement. | May be throw-over, davit-launched or float free, depending on its type and ship arrangement. |
| Protection | Rigid structure and, where fitted, enclosed or partially enclosed protection. | Inflatable buoyancy and canopy protection from exposure after deployment. |
| Manoeuvrability | Powered boats can move away from the ship and manoeuvre under command. | Limited manoeuvrability; depends on paddles, sea anchors, towing and rescue assistance. |
| Equipment | Engine-related systems, steering, communications, compass and survival equipment as approved. | Canopy, painter, sea anchors, lights, rescue line and survival pack as approved. |
| Main risk | Launching, release gear, falls, davit movement, boat impact and recovery hazards. | Inflation failure, damage, incorrect stowage, exposure, overcrowding and servicing defects. |
| Maintenance focus | Hull, engine, fuel, steering, falls, davit, hooks, release gear and equipment. | Container, fabric, inflation system, painter, hydrostatic release, pack and approved service. |
Which craft should you use in an emergency?
The crew should not make an individual decision based on a general preference for lifeboats or life rafts. The correct craft is the one assigned by the muster list and directed by the Master or responsible officer. The ship’s plan accounts for capacity, location, embarkation routes, launching arrangements, weather, damage condition and the number of people onboard.
If a lifeboat station is inaccessible, damaged, unsafe or cannot be launched, the command team may direct people to another survival craft. That decision belongs to the ship’s emergency organisation. Crew members should report blocked routes, missing equipment, damaged access or unsafe stowage during normal inspections rather than waiting for an emergency.
Launching and boarding: why preparation matters
A survival craft is useful only when people can reach it and board it safely. SOLAS Chapter III addresses muster lists, embarkation arrangements and launching stations because the sequence begins before the craft moves.
Take the assigned route, wear the required personal life-saving equipment and report to the station. Do not run, return for personal items or leave the muster area without instruction.
The responsible team checks attendance, assists injured or vulnerable persons and reports missing people through the command structure.
Follow the posted instructions. Check only the items and actions assigned to your role. Do not operate release gear or launching controls without competence and authorisation.
Keep access clear, follow the boat officer or raft leader and distribute people according to the craft’s instructions and capacity.
Wait for the command. Watch for ship-side hazards, falls, painter tension, floating debris, propellers and the movement of the craft.
What happens after a life raft inflates?
Once a life raft is waterborne, the occupants must remain organised. The canopy should provide shelter as designed. The sea anchor helps reduce drift and can orient the raft. The painter connects the raft to the vessel during deployment and must be handled according to the instructions. The raft leader should account for people, check injuries, distribute duties and protect the survival equipment.
The survival pack may contain water, food, first-aid materials, signals, a repair kit, bailers, sponges, a knife, paddles and other equipment. The contents depend on the approved pack and applicable requirements. Do not open or use supplies unnecessarily. Follow the survival instructions, make signals when rescue is likely to see them and avoid creating avoidable damage to the raft.
A life raft can be stable and protective, but it is still exposed to wind, waves, cold and heat. Occupants should reduce heat loss, keep the canopy closed as appropriate, remove water from the floor, care for injured people and maintain lookout and communications. A life raft is a survival platform, not a hotel room.
What happens inside a lifeboat?
A lifeboat’s rigid structure and equipment may provide greater protection and control, but occupants still face serious hazards. The boat must be launched without striking the ship. The engine, steering, fuel and communications must work. The crew must follow the coxswain or boat officer, secure loose equipment, maintain ventilation and manage the craft’s resources.
If the lifeboat has an engine, operators must know its starting system, cooling requirements, fuel arrangements, emergency stop and steering. If it is a free-fall lifeboat or a davit-launched boat with release gear, the crew must understand the approved sequence. A lifeboat should never be treated as safe simply because it has a rigid hull.
Maintenance: lifeboats and life rafts need different attention
IMO’s LSA Code provides technical requirements for manufacture, testing, maintenance and records. SOLAS requires life-saving appliances to be operationally ready, and the ship’s SMS should define inspection and maintenance responsibilities.
Lifeboat maintenance includes the hull, seats, drain arrangements, engine, fuel, steering, battery, communications, compass, searchlight, fire equipment, survival supplies, release gear, falls, davit, winch, brake and securing arrangements. The details depend on the boat and manufacturer.
Life-raft maintenance focuses on the container or valise, inflation system, cylinders, fabric, seams, valves, painter, sea anchors, canopy, lights, survival pack, hydrostatic release arrangement and stowage. A raft may look untouched while its service date has expired or its hydrostatic release unit is no longer valid.
IMO’s safety framework requires maintenance, thorough examination, operational testing, overhaul and repair of lifeboats, rescue boats, launching appliances and release gear under the applicable authorised-service-provider arrangements. Records should be kept onboard and defects should be corrected before the equipment is relied upon.
Life-raft servicing in India
DGMA’s Life-Saving Appliances information states that the Nautical Wing oversees testing, approval, certification and inspection of life-saving appliances for Indian-flag vessels. It identifies a maximum servicing interval of 12 months for inflatable life-saving appliances including liferafts and points to DGS-approved service stations under Merchant Shipping Notice 08 of 2025.
For an Indian vessel, the company should verify the service station’s current approval, competent-person arrangements, equipment serial numbers, certificate numbers and servicing records. Do not assume that a local inflatable-boat repair shop is an approved life-raft service station.
The same principle applies to replacement parts. DGMA’s guidance explains that approved equipment is accepted as a complete unit and does not permit casual substitution of components. Use the manufacturer’s approved parts and the current statutory procedure.
Training: PST, PSCRB and Fast Rescue Boat
Personal Survival Techniques, or PST, provides foundational survival training. Proficiency in Survival Craft and Rescue Boats, commonly called PSCRB, is a specialised STCW competency for designated crew who may take charge of a survival craft or rescue boat. Fast Rescue Boat duties may require a separate course.
IMO identifies Model Course 1.19 for Personal Survival Techniques, Model Course 1.23 for Proficiency in Survival Craft and Rescue Boats other than Fast Rescue Boats and Model Course 1.24 for Proficiency in Fast Rescue Boats. The actual certificate and refresher requirements depend on the flag administration, employer and current rules.
How to book genuine MTI training in India
Ask whether you need PST, PSCRB, Fast Rescue Boat, refresher training or ship-specific familiarisation.
Use DGMA’s current approved-course list. The phrase “survival course” is too broad to confirm a certificate.
Check the official approved-MTI directory and any withdrawal or suspension notices before making payment.
Confirm tuition, practical work, assessment, certificate, taxes, accommodation, medical requirements and reattempt charges.
Save the invoice, receipt, attendance, result and certificate. Ask how the certificate is verified for joining, CDC or revalidation.
What does survival-gear compliance cost?
There is no single price for lifeboat or life-raft compliance. Lifeboat costs depend on the boat type, engine, davit, falls, release gear, annual or five-year service scope, authorised provider, class or flag attendance, spare parts and repairs. Life-raft costs depend on raft capacity, brand, pack, cylinder, hydrostatic release unit, service station, location, transport and replacement items.
Training fees depend on the course, institute, city, practical facilities, assessment and certificate. Request a written quotation that separates inspection, servicing, parts, certification, attendance, transport, taxes and re-testing. A low-cost certificate that does not include the required examination or approved service is not a real saving.
Common lifeboat and life-raft scams
- “All survival craft are the same”: lifeboats, liferafts, rescue boats and launching appliances have different duties and requirements.
- Expired raft service accepted: verify the service date, station approval, serial number and certificate.
- Fake SOLAS certificate: a decorative certificate is not evidence of approved manufacture, testing or servicing.
- Unapproved replacement parts: do not substitute valves, cylinders, HRUs, hooks or other components without approval.
- Guaranteed PSC pass: legitimate servicing cannot guarantee that every inspection will find no deficiency.
- Guaranteed PSCRB pass or job: genuine training requires attendance, competence and assessment and cannot guarantee employment.
- Unsafe drill videos: a video cannot replace the ship-specific manual, risk assessment or authorised drill plan.
Frequently asked questions
Is a lifeboat safer than a life raft?
Neither is automatically safer in every situation. A lifeboat may provide rigid structure, propulsion and greater manoeuvrability. A life raft may deploy quickly and provide buoyancy and canopy protection. The correct craft is the one assigned and available under the ship’s emergency plan.
Can a life raft float free automatically?
Some approved life-raft arrangements use a hydrostatic release system for float-free deployment. The equipment must be correctly fitted, within service date, unobstructed and maintained according to the applicable requirements.
Do all lifeboats have engines?
Many do, but the exact arrangement depends on the approved design and ship. Do not assume that every lifeboat has identical propulsion, steering or launching features.
How often is an inflatable life raft serviced?
DGMA’s current information shows a maximum 12-month servicing interval for inflatable life-saving appliances including liferafts in the Indian framework. Confirm the current flag-State, manufacturer and service-station requirement for the vessel.
Can crew launch any survival craft they prefer?
No. Crew must report to the assigned muster station and follow the Master’s or responsible officer’s direction. The ship’s approved arrangement determines the craft, capacity and launching method.
Which training is needed for a lifeboat?
Designated survival-craft personnel generally need PSCRB, while basic crew may need PST and Fast Rescue Boat operators may need separate training. Verify the current company, flag-State and DGMA requirement.
Final lifeboat and life-raft readiness checklist
- Know your muster station, assigned craft and emergency duties.
- Keep access routes, embarkation stations and launching paths clear.
- Check that the craft’s capacity, equipment and stowage match the approved arrangement.
- Keep lifeboat engine, fuel, steering, batteries, davit, falls and release gear ready.
- Keep liferaft containers, painters, HRUs, service dates and survival packs traceable.
- Use only approved service stations and authorised technical personnel.
- Record inspections, maintenance, tests, defects, repairs and certificates onboard.
- Participate seriously in drills without bypassing safety controls.
- Verify PST, PSCRB and Fast Rescue Boat training through current DGMA sources.
- Report any damaged, expired, blocked or missing life-saving appliance immediately.
The lifeboat and the life raft are not competitors. They are parts of a layered survival system. One may provide propulsion and rigid protection. The other may provide rapid buoyancy and shelter when time is short. Their value depends on the same foundation: correct design, approved equipment, accessible stowage, trained people, current servicing and disciplined emergency command.
When the alarm sounds, the most important survival decision has usually been made long before the emergency. It was made when the crew attended the drill, read the muster list, checked the service date, reported a damaged painter, questioned an uncertain certificate and learned the actual craft carried by the ship. Preparation turns survival equipment into a real chance of survival.
