Life rafts are critical survival gear, designed to protect crews and passengers in emergencies. But like all marine safety equipment, they have a limited service life. So how long can a life raft last? The answer depends on the type of raft, the materials used, and how well it is maintained. At Life Raft Professionals, we provide coastal, offshore, and SOLAS-approved rafts with long service lives when properly cared for.
Average Service Life of a Life Raft
Most modern life rafts are designed to last between 12 and 15 years, with some commercial-grade rafts lasting even longer if serviced regularly. Manufacturers set specific guidelines for replacement and inspection based on the raft’s construction and approval type.
Factors That Affect Lifespan
Material Construction
Rafts built from durable materials such as neoprene or polyurethane often last longer than economy models. These materials resist UV damage, saltwater exposure, and abrasion better than basic PVC designs.
Storage Conditions
Proper storage is essential. Rafts kept in deck canisters face exposure to sun, salt, and weather, while those stored in valises may be better protected. Extreme temperatures or poor storage can shorten a raft’s lifespan.
Servicing and Inspections
Regular service—typically every 1 to 3 years—is required to maintain certification. During service, technicians check the inflation system, buoyancy tubes, canopy, and survival gear to ensure everything is functional.
How Long a Raft Can Stay Afloat
While a raft’s total service life may span a decade or more, its ability to remain afloat once deployed is measured in days or weeks, depending on conditions. Offshore and SOLAS-approved rafts are tested to survive longer rescues, while coastal rafts are designed for short-term emergencies.
SOLAS Standards and Commercial Liferafts
SOLAS-approved rafts meet strict international standards. These rafts are not only designed for long-term durability but also equipped with survival packs for extended emergencies. With proper servicing, they can remain reliable for many years of operation.

FAQ
How long can a life raft last in storage?
With proper servicing, most rafts can last 12–15 years or more, depending on the manufacturer’s guidelines and material construction.
How long can a life raft float once deployed?
Modern rafts can float for days to weeks, depending on sea conditions and design. SOLAS rafts are tested for extended survivability offshore.
Does servicing extend a raft’s life?
Yes. Regular service ensures the inflation system, canopy, and survival equipment remain in working condition, extending safe use.
Can an expired raft still be used?
No. Expired rafts may not inflate properly or meet safety standards. Replacements should follow the manufacturer’s recommended timeline.
Which rafts last the longest?
SOLAS-approved commercial rafts typically last the longest due to superior construction and strict testing standards.
Conclusion
So, how long can a life raft last? With proper storage and servicing, most rafts will remain reliable for over a decade. However, once deployed, they are designed for temporary survival until rescue arrives. At Life Raft Professionals, we provide coastal, offshore, and SOLAS-certified rafts to ensure you are protected for the long run and ready when it matters most.
