Coastal budget to bluewater premium.
- Budget coastal (~£1,500): Plastimo Cruiser ISO 9650-2 — UK/Med default.
- Offshore overall (~£2,200): Ocean Safety Ocean ISO 9650-1 — Pack 1 survival kit.
- Charter / hire (~£1,400): Crewsaver Hire ISO — built for commercial cycle.
- Premium (~£2,800): Viking RescYou Pro — SOLAS-grade build.
- Ultra-premium / racing (~£3,800): Switlik MD-4 — US Coast Guard spec, ISAF compliant.
Before the products: four real questions.
1. ISO 9650-1 or 9650-2?
9650-1 = offshore, full equipment, 24+ hour survival — required for ocean passages or any route where SAR could be more than a day. 9650-2 = coastal, lighter pack, sub-24-hour rescue expectation — fine for inshore and well-patrolled waters. The 9650-1 costs 30–60% more, but don't save money here if you're crossing the Bay of Biscay.
2. Cradle or valise?
Cradle (canister) on deck — instantly accessible, deploys with one pull, but exposed to weather (the canister protects it). Valise in a locker — protected and cheaper to mount, but you must carry 30–45 kg to the rail in a crisis. Offshore: cradle. Coastal with limited deck space: valise, but within 5 seconds' reach.
3. Pack 1 or Pack 2?
Pack 1 = full survival contents (24h+ food and water, full signalling including parachute flares and dye, repair, fishing, first aid, thermal protection). Pack 2 = coastal subset. Pack 1 is non-negotiable offshore; Pack 2 is acceptable inshore if your grab bag fills the gap. Pack 1 adds £300–500.
4. How many persons?
Rafts are rated by maximum capacity — buy for your maximum on-board count, not normal. Common sizes 4/6/8/10; a 6-person is typically £200–400 more than a 4-person of the same model. For a couple, a 4-person is the right capacity-vs-cost balance.
Quick spec comparison.
The five picks, in detail.
Plastimo Cruiser ISO 9650-2
Best budget coastalThe default coastal cruising raft for European sailors on a budget. ISO 9650-2 (up to 24-hour rescue expectation), double floor for insulation, twin buoyancy tubes, self-righting in moderate seas.
Weekend and coastal cruising in European waters within reasonable SAR response. Plastimo's service network is extensive across the UK and Med.
Not rated for ocean passage. The 3-yearly service is shorter than some premium rafts. Crossing the Bay of Biscay or the Channel in winter? Step up to a 9650-1.
Ocean Safety Ocean ISO 9650-1
Best offshore overallBritish-built offshore raft. ISO 9650-1 for ocean passages, Pack 1 survival kit (24h+ rations, signalling, repair, first aid), insulated double floor, full canopy with rainwater collection.
Bluewater cruisers, Channel and Biscay crossings, transatlantic, ARC. The Pack 1 contents give real survival capability beyond 24 hours, with strong UK service support.
Heavier than coastal rafts — 38 kg in valise form is at the limit of one-person deployment. Cradle-mount is the safer offshore choice. Higher service cost (~£300–400).
Crewsaver Hire ISO 9650-2
Best for charter & hireThe workhorse of the UK and Med charter fleet. ISO 9650-2 coastal rating, designed for high-cycle hire use, lower acquisition cost balanced by an annual service requirement.
Charter operators, sailing schools, hire fleets. Easier to insure for commercial use than premium rafts and cheaper to replace. Crewsaver service centres in every major UK port.
Annual service (~£200/yr) means 3-year ownership approaches a Pack 1 raft on 3-yearly service. Coastal-only rating.
Viking RescYou Pro ISO 9650-1
Best premiumDanish-built premium offshore raft — SOLAS-grade construction in a recreational package. Reinforced canopy, larger water-ballast pockets for heavy-sea stability, premium survival pack.
World cruisers and ARC participants who may be out of SAR range for extended periods. Viking builds most commercial-ship liferafts — the standard is genuinely higher than typical recreational rafts.
Canister-only — must be cradle-mounted. Heavier than valise rafts. Mandatory annual service (~£350) plus a 12-yearly inflation test (~£600). Total ownership exceeds the headline.
Switlik MD-4
Ultra-premium / racingUS-built premium offshore raft used by the US Navy and Coast Guard for SAR. ISAF / World Sailing offshore-racing compliant. Triple buoyancy tubes, oversize ballast pockets, reinforced canopy and floor.
Offshore racing (RORC, ARC, Sydney Hobart) and serious bluewater cruisers who want the same raft the US Coast Guard uses. Compliant with most international racing rules out of the box.
Much pricier than European equivalents. The service network outside the US is thinner — allow time and cost for shipping. Heavier and bulkier than ISO-spec rafts.
The real cost: ten years of ownership.
The sticker price is the first cheque. Service is mandatory, and a decade of services typically costs more than the raft. Approximate 10-year ownership for a 4-person raft:
Other things to know.
Service intervals — actually mandatory
Liferaft service isn't optional or DIY. Skipping it voids insurance and almost certainly means the raft won't inflate. Intervals are 1 or 3 years by model and tier; the first service is sometimes deferred 2–3 years from manufacture — read the documentation.
Where to mount it — actually critical
A raft is only useful if reachable and deployable in seconds, by one person, in heavy weather. Coachroof, transom rail, or pushpit are standard on cruising yachts. Lazarette stowage works for valise rafts if you can move 35 kg through a hatch fast. Test the path with a weight before you trust it.
Grab bag — the missing piece
Even a Pack 1 survival pack is the minimum. A waterproof, briefcase-sized grab bag doubles your effective time in the raft: handheld VHF with DSC, PLB, EPIRB, passports, extra water and rations, hand flares, fishing line, spare medicine, a knife. See our emergency procedures guide for the full list.
Hire vs buy
Several UK suppliers offer hire from ~£200/week or ~£500/season — worth it for one-off offshore passages (ARC qualification, one summer cruise). Ownership becomes cheaper than hire at around 18 months of regular use.
Used liferafts — sometimes fine, sometimes a trap
A used raft can save real money — but only with documented service history and time left before its end-of-life inflation test. A used raft with no paperwork is worthless. Budget an immediate ~£250 service and check the maximum age (typically 12–15 years from manufacture).
FAQ.
Do I need a liferaft for coastal cruising?
Not legally for private craft in most UK/EU jurisdictions for coastal use — but every cruising school and offshore racing rule requires one. In practice, if you sail more than 5 NM from a safe haven, the answer is yes.
SOLAS vs ISO 9650?
SOLAS rafts are commercial-shipping spec — 30+ day survival, much heavier and pricier (£5,000+). ISO 9650 is the recreational standard, fit for sailing yachts. A SOLAS raft on a yacht is over-spec and the weight penalty matters more than the margin. Stick with ISO 9650-1 or -2.
When should I replace it entirely?
Manufacturers specify a maximum age — typically 12 years from manufacture, some allowing 15 with clean service history. Beyond that the fabric degrades and it can't be certified. Replace it then, or earlier if a service reveals a failed pressure test or significant damage.
Can I deploy one for practice?
Yes — some service centres offer training deployments where you inflate the raft, get in, and learn the drills (~£50–100 on top of service). Strongly recommended in the first year. The first time you pull the painter shouldn't be a real abandon-ship.
How long does it take to deploy?
Decision to fully-inflated, painter attached: ~30–60 s for a cradle-mounted canister with a prepared crew; 2–4 min from a locker with a valise if all goes well, longer if not. This is why cradle-mounted is the safer offshore choice.
