Safety Gear for Offshore Sailing: What to Carry and How to Use It

The best safety gear on a cruising boat is the gear you never use. The second best is the gear you've practiced with so thoroughly that deploying it in an emergency is muscle memory, not improvisation. The worst is the gear sitting in a locker you haven't opened since you bought the boat.

This article covers the core safety equipment for an offshore cruising boat — what to carry, how to set it up, and the practices that make the difference between a system that works under pressure and one that exists only on paper.

Personal Safety: PFDs, Harnesses, and Tethers

The modern offshore PFD has converged into an integrated unit: an inflatable lifejacket with a built-in deck harness and tether attachment point. The Spinlock Deckvest range and the Crewsaver ErgoFit are the current benchmarks, but several manufacturers make excellent units. What matters is the specification, not the brand.

For offshore sailing, your PFD should have a minimum of 150 Newtons (33 lbs) of buoyancy, an integrated harness rated to ISO 12401, a crotch strap (prevents the jacket from riding up over your head in the water), a spray hood (prevents inhalation of spray in breaking seas), a light and whistle (SOLAS minimum), and ideally a personal AIS beacon and SOLAS-grade reflective tape.

Hydrostatic inflation mechanisms are strongly preferred over the older dissolving-tablet triggers. The tablet type is prone to accidental inflation in wet offshore conditions — which is not just annoying but potentially dangerous if it happens while you're working on the foredeck. Hydrostatic units inflate only when submerged to a specific depth, which dramatically reduces false activations.

Every crew member should have their own PFD, fitted to them personally, over the foul weather gear they'll actually be wearing. A PFD that fits perfectly over a t-shirt but won't close over a sailing jacket is useless.

Tethers connect your harness to the boat. The standard for offshore sailing is a double tether: one short leg (approximately 1 meter) for when you're stationary at a work station, and one long leg (approximately 1.8 meters) for transiting the deck on jacklines. The critical principle from World Sailing's Offshore Special Regulations bears repeating: harnesses and tethers are not designed to tow a person through the water. The goal is to keep you on deck, not to drag you alongside at 7 knots. Use the shortest tether practical for every task.

Inspect tethers before every passage. Look for chafe on the webbing, corrosion on the clips, and the overload indicator flag stitched into the webbing (a colored flag that shows if the tether has been shock-loaded beyond its rating). A tether that's been overloaded must be replaced immediately.

Jacklines: The Highway System

Jacklines run fore and aft along the deck, providing a continuous attachment path so crew can move from cockpit to bow without unclipping. They should be rigged before every offshore passage and removed when not needed (UV degrades them).

Use flat polyester webbing, not wire and not round rope. Wire rolls underfoot and can trip you — exactly what the jackline is supposed to prevent. Round rope has the same problem. Flat webbing lies flat on deck and provides secure footing.

Rig jacklines as far inboard as practical. The goal is that if you fall while clipped to a jackline, the tether length keeps you on deck rather than swinging outboard over the lifelines and into the water. Jacklines run along the cabin top or on the centerline achieve this better than jacklines along the side decks.

Tension them tight. A slack jackline allows too much lateral movement, increasing the risk of going overboard while clipped on. Use a purchase system or Dyneema loops to cinch the tail end tight.

Install dedicated padeyes (folding or fixed, through-bolted) at the companionway, in the cockpit at the helm position, and at the mast base. These provide fixed clip-in points for positions where you're stationary. Never clip to a stanchion, a lifeline, or a pedestal guardrail — none of these are designed to take the shock load of a falling body.

The Life Raft

The life raft is the most expensive, least used, and most critical piece of safety equipment aboard. It exists for one scenario: the boat is sinking and you need to abandon ship. The old maxim applies — always step up into the life raft. If you're stepping down, the situation hasn't deteriorated enough to abandon.

For offshore cruising, carry a raft certified to ISO 9650-1 (the international standard for leisure craft life rafts) or SOLAS. Size it for the full crew — but don't oversize. A four-person raft with three people in it is more stable than an eight-person raft with three people, because the occupants' weight lowers the center of gravity.

Storage options are canister (deck-mounted in a rigid container with hydrostatic release) or valise (soft bag, typically stored in a cockpit locker or below decks). Canister mounting with a hydrostatic release is preferred for bluewater sailing. If the boat sinks rapidly, the hydrostatic release deploys the raft automatically without crew intervention. A valise stored below decks requires someone to physically carry it on deck and deploy it — which may not be possible in a flooding emergency or a capsize.

Life rafts require servicing per the manufacturer's schedule — typically every 1-3 years depending on the model. This is not optional. An unserviced raft may not inflate, may have degraded fabric, or may have expired provisions. The servicing cost is a fraction of the raft's value and an infinitesimal fraction of your life's value.

The Ditch Bag

The ditch bag is what you grab on the way to the life raft. It should be a waterproof, brightly colored bag with inherent flotation, stored where you can reach it in under 30 seconds from the companionway. Contents should include:
