A life raft is the last piece of safety equipment you will ever deploy. It comes out when the boat is gone — or going — and everything else has failed. Because of that, it lives in a locker or on deck for years at a time, never touched, never tested, and never confirmed to be functional. The sailors who abandon ship into a raft that inflates properly are lucky and prepared. The ones who abandon into a raft that doesn't inflate, or who have to leave it behind because it's stowed below and there's no time, are neither.
Understanding what you're buying, how to store it, and what the service interval actually means is not an academic exercise. It is the practical work that determines whether the raft earns its place aboard.
The Legal Question (and Why It Doesn't Answer the Real Question)
In the United States, there is no federal requirement for recreational vessels to carry a life raft. The USCG requires a Type I, II, or III lifejacket for each person aboard, certain visual distress signals, and a throwable device — but not a life raft. This is not because life rafts are optional equipment for offshore sailing. It is because US recreational boating law was largely written for coastal and inland use, and the regulatory framework has never caught up with the reality of offshore passage making.
The practical question is not what the law requires; it is what you need if your boat sinks 200 miles offshore. The answer to that question is almost always: a properly equipped life raft, stowed accessibly, in good service condition. Most experienced offshore sailors treat a life raft as a non-negotiable item for any passage more than 50 miles offshore. The accepted risk of not carrying one exists — it is a real choice that real sailors make, sometimes with good reasoning about coastal proximity and good weather — but that risk should be made consciously, not because the option of not carrying one was easier or cheaper.
Standards: What the Ratings Actually Mean
Life raft standards exist on a spectrum from SOLAS at the top to no certification at the bottom. Understanding the middle of that spectrum — where recreational offshore rafts live — is what matters for most sailors.
SOLAS-A (Safety of Life at Sea, Class A): The highest standard. Required on commercial vessels in international trade. Tested in the most severe conditions, built to the most stringent specifications, packed with the most comprehensive survival equipment. SOLAS rafts are heavy, large, and expensive — and they are built to be deployed by commercial crews with training, not by exhausted recreational sailors at 2 am. SOLAS-A rafts are not usually the right choice for recreational offshore sailing; they're heavier and larger than necessary, and their service costs are higher. If you see a SOLAS raft advertised for recreational use, it is worth understanding that the standard was written for a different context.
ISO 9650-1 (Group A — offshore recreational): The correct standard for serious offshore recreational sailing. ISO 9650-1 Group A rafts are tested in water at 10°C and 50-knot wind conditions — conditions that represent genuine offshore exposure. They must self-right if inflated upside down, provide thermal protection, include a sea anchor, and be packed with a minimum survival kit. The reputable manufacturers in this category — Switlik, Winslow, Viking, Revere, RFD — have established track records and service networks. This is the standard to specify when shopping for a raft that will go offshore.
ISO 9650-1 Group B vs. Group A: Within ISO 9650-1, Group B rafts are tested in less severe conditions (17°C water temperature) and are rated for deployments within 50nm of shore. Group A is the offshore standard. When comparing rafts, confirm which group applies — Group B is sometimes sold as an "offshore" raft in marketing materials, which is imprecise.
ISO 9650-2 (inshore recreational): Rated for use within 50nm of shore, tested in mild conditions. Adequate for coastal cruising and daysailing where a liferaft-level emergency is followed by a short survival window. Not appropriate for offshore passages. The line between coastal and offshore is real, and it's roughly the distance at which helicopter rescue becomes uncertain.
No certification: Avoid. The budget life rafts sold on marine discount websites with no ISO or SOLAS certification have not been independently tested. You do not know whether they will inflate, whether the inflated structure can support your crew weight, or whether the CO2 cylinder was filled correctly. A life raft that does not work is worse than no life raft — it produces false confidence and costs money that could have gone toward a properly certified raft.
What's Inside a Proper Life Raft
The survival equipment packed inside a life raft varies significantly by manufacturer and model. Before purchase, request the full equipment list for the specific model. After purchase, read the service certificate carefully after every service — it documents exactly what was repacked.
A properly equipped offshore recreational raft should include:
Water: Sealed water pouches (not bottles — they corrode and fail) providing at least 500ml per person for the rated capacity. The pouches have expiry dates; they are checked and replaced at service.
Rations: Emergency calorie bars providing a minimum two-day supply per person. High energy density, palatable cold and wet, with long shelf life.
Flares: At minimum, handheld red flares and parachute flares. Count them on the service certificate — the number matters. An offshore raft should have six flares or more.
First aid: A basic kit covering wound sealing, pain management, and seasickness. The offshore medical kit article covers what should be in the kit you bring aboard from your abandon ship bag; the raft's built-in kit is a backup for the backup.
Thermal protection: Insulating blankets or a thermal protective aid for each person. In water temperature below 15°C, hypothermia is the primary killer in the hours after abandonment. Thermal protection buys time.
Sea anchor (drogue): Deployed from the raft to slow drift, reduce instability in waves, and orient the raft — most rafts are more stable with the sea anchor deployed. Learn how to use it before you need to.
Bailing bucket and sponge: Inflated life rafts collect water. Bailing is necessary work in anything other than calm conditions.
Knife: For cutting the painter line if the raft deploys near a sinking vessel and the suction pulls toward it. A raft knife should be blunt-tipped (to avoid puncturing the raft), serrated for cutting line, and secured inside the raft, not stored where it can work loose.
Pump: For topping up buoyancy tubes that may lose pressure over time in a deployment.
Check the service certificate after every service. If items are listed as "not replaced — condition acceptable," ask why. A raft that returns from service with out-of-date flares and water pouches has not been properly serviced.
Storage: Valise vs. Canister
Life rafts are packed in one of two configurations, and the difference matters for how quickly you can deploy them.
Valise (soft bag): The raft is packed in a fabric bag, typically bright orange or red, with handles. It stows in a locker, under a bunk, or in a cockpit locker. The advantage is flexible stowage — a valise can go into spaces that a rigid canister cannot. The disadvantage is that in an emergency, you must physically carry or drag the valise from below to the deck before deploying it. In a flooding boat with a panicking crew, this step costs time. Valise rafts also sit in bilge water if stored improperly, which accelerates degradation.
Canister (rigid fiberglass or plastic): The raft is packed in a hard-sided canister mounted on deck in a cradle. It is always in position, always accessible from the cockpit, and — crucially — it can be fitted with a hydrostatic release that automatically deploys the raft if the boat sinks. For offshore sailing, a deck-mounted canister with a hydrostatic release is the gold standard. The disadvantage is that it takes up permanent deck space, is more expensive, and requires deck fittings capable of bearing the load of the cradle and canister.
For any offshore passage, the canister on deck is the right answer. If budget or deck space constraints require a valise, store it in the most accessible position possible — typically the cockpit locker nearest the companionway — and drill the retrieve-and-deploy sequence until it is automatic.
The Hydrostatic Release
A hydrostatic release unit (HRU) is a small device that automatically severs the lashing holding the raft canister in its cradle when submerged to 1.5–4 meters. If the boat sinks suddenly, the raft floats free, the painter line pulls taut as the raft descends with the boat, and the inflation mechanism triggers automatically. The raft inflates, the painter line — designed to break before the raft is pulled under — parts or releases, and the raft surfaces with the inflation complete.
This automatic deployment requires no action from the crew. It works whether the crew is unconscious, trapped, or already in the water. For offshore sailing, where sinkings can be sudden and violent, it is the difference between a crew that has a raft and a crew that does not.
Hydrostatic releases have an expiry date — typically two years. It is printed on the device. An expired HRU may not release. Check it every time you check the raft canister. Replace it on schedule. The replacement cost is small relative to the cost of a raft that doesn't deploy.
Service Intervals and What They Mean
Manufacturers require periodic service to maintain the raft warranty and, more importantly, to confirm the raft will function. Service intervals vary: most manufacturers specify annual service for the first several years, then may allow three-year intervals for rafts in good condition stored in appropriate environments. Check your manufacturer's current service requirements — do not rely on what you were told when you bought the raft.
At service, a certified facility repacks the raft, replaces out-of-date consumables (water, rations, flares, CO2 cylinder), pressure-tests the inflation system, inspects the canopy, floor, and buoyancy tubes, replaces the hydrostatic release if needed, and issues a service certificate documenting everything that was done. The service certificate is the document that tells you whether the service was thorough or cursory.
Service costs are typically $300–600 depending on raft capacity, manufacturer, how many consumables need replacement, and whether the canister requires resealing. The cost is significant. It is also non-negotiable if you want a raft you can trust. A raft that hasn't been serviced in five years has an inflation system of unknown reliability and consumables that are almost certainly expired. It is not a safety item — it is ballast.
