Kayak, Paddleboard and Jet Ski Safety: The Wind You Cannot Feel

Why the Small Craft Are the Ones That Drown People

Look at any national boating-fatality report and the pattern is the same. The US Coast Guard's annual recreational boating statistics have for years put kayaks and canoes second only to open motorboats for deaths, on a fraction of the hours afloat, and the RNLI and coastguards around Europe have watched paddleboard rescues climb every summer since inflatable boards became a supermarket purchase. The victims are rarely experienced. They are usually not wearing a lifejacket. And the cause of death is almost always the same word: drowning, very often in water cold enough that the swim they thought they could make was never on.

Four things stack up against the small craft, and none of them is skill. First, cold water. Anything below about 15°C (59°F) triggers cold-water shock on immersion: a gasp, then a minute or more of uncontrolled breathing during which a person without flotation can inhale water and drown in the first two minutes. Most northern European and North American waters are below that for most of the year. Second, no lifejacket, because it was hot and the trip was short. Third, offshore wind, which we get to next. Fourth, no way to call: the phone was in the car, or in a pocket, where it died on contact with the sea. A yacht that gets into trouble has a VHF, flares, a crew and freeboard. A paddler in trouble has whatever is zipped to their body.

Underneath all four is perception: nobody on a paddleboard feels they are going to sea, so they prepare for a walk on the beach.

The Offshore-Wind Trap: Easy Out, Impossible Back

Stand on a beach with the wind at your back, blowing out to sea. The water in front of you is flat, because waves need distance to build and the wind has only just left the land. The sky is probably clear. It looks like the best paddling day of the year, and that is exactly the problem.

Push off and you are going downwind. A stand-up paddler is, in effect, a small sail of about half a square metre, and a board with a few centimetres of draft has nothing below the water to resist it. The wind adds to your paddle speed, the water stays smooth, and because you are moving with the air you feel almost no breeze on your face. That is the part people miss. The apparent wind on a board doing 3 knots downwind in 12 knots of breeze is 9 knots from behind, which registers as nothing at all. Twenty minutes pass, the beach looks small, and you turn round.

Now the same 12 knots is in your face plus your own speed, the sea is choppier because you are further out where the waves have had room to grow, and your sail is working against you. A fit adult paddling flat out on a touring board makes perhaps 3 to 3.5 knots in still air. Into 12 knots of wind and chop most recreational paddlers make less than half that, and at 15 knots a standing paddler often makes nothing. The board goes backwards between strokes. The only progress is on your knees or lying prone, and that is exhausting and slow.

The defence is a habit, not a piece of kit. Before you launch, find out which way the wind is blowing and whether it is forecast to build. Flags, smoke, the direction the moored boats point (bows into the wind) and the ripple on the water all tell you. If it is blowing off the land, start by paddling upwind along the shore so the return is the easy leg, stay within a distance you could swim, and turn back well before you are tired. If it is over about 10 knots offshore and building, do something else today. Onshore wind is uncomfortable but forgiving: it brings you home. A wind along the beach (cross-shore) can still set you towards a headland or out of a bay, so read where it will actually take you, not just its strength.

If you are caught, do not try to swim for it. The board or kayak is your flotation and your visibility; a head in the water is invisible at 200 m. Get low, kneel or lie down to shrink the sail, paddle for the nearest land downwind rather than the beach you left, and call early. Coastguards would far rather turn a lifeboat round than search for a body.

Leashes: the Right One Depends on the Water

A SUP leash exists for one reason: to keep the biggest flotation device you own attached to you when you fall off, because in wind a loose board travels faster than you can swim after it. On the sea, on a lake and in surf, a coiled leash on the ankle or calf does this well. The coil keeps it out of the water so it does not drag, and it does not catch on anything.

On a river, or anywhere with real current, an ankle leash can kill you. Fall off, the board snags on a branch, a rock or a bridge pier, and the flow pins you underwater on the end of 3 m of cord you cannot reach to release. British Canoeing, the RNLI and river safety bodies across Europe have all issued the same warning after a series of drownings, and the fix is the same: a quick-release waist belt, with the leash clipped to a toggle at your front that either hand can pull even under load. Pull it and you are free of the board; the board can be recovered later. It is what the professionals wear on moving water, and it is what you should wear too.

Kayaks are different. You are mostly attached to the boat by sitting in it, and a leash on the body is a snag hazard rather than a safety aid. What a kayaker wants is a paddle leash on open water so the paddle is not lost in a capsize, deck lines to hold onto, and a re-entry method rehearsed in shallow water: a paddle float and stirrup for a sit-in, or simply the technique of climbing back on a sit-on-top from the side, which is harder than it looks when cold.

Flotation: Wear It, Every Time

A lifejacket strapped to the deck is luggage. Cold-water shock takes your breathing away in the first seconds of immersion, and the idea that you will calmly retrieve and put on a lifejacket while gasping in 12°C water is a fantasy. It is worn or it does not exist.

For kayaking, the standard is a buoyancy aid: a foam vest of around 50 newtons (ISO 12402-5) that supports you without turning you face-up, so you can swim, climb back in and paddle without restriction. It works unconscious or not, which inflatable belts do not. For SUP, the honest compromise most paddlers make is an inflatable waist belt: a pouch on a belt, pulled round to the front, that inflates a horseshoe when you tug the toggle. It stays out of the way of your stroke and is far more likely to be worn than a vest on a hot day. Its weakness is that you have to be awake and able to pull it. On cold water, in surf or if you cannot swim well, wear the foam vest.

Rules vary. The US Coast Guard classes a paddleboard used outside a designated swimming or surfing area as a vessel, which means a wearable PFD must be aboard for each person and children of a state-defined age must wear it. Many European countries have no legal requirement for adults but their coastguards ask for one in every campaign, because the rescues tell them what happens without it. Whatever the law where you launch, the body-count says the same thing everywhere.

A Way to Call, and Someone Who Knows

A phone in a proper waterproof pouch on a lanyard round your neck, or in a chest pocket of the buoyancy aid, is the minimum. Test that you can work the touchscreen through the pouch with wet hands, and know the emergency number where you are (112 across the EU, 999 in the UK, 911 in the US). Better still on the sea is a small handheld VHF clipped to your vest: it reaches the coastguard and every boat around you on channel 16 at once, it floats, and it does not depend on a mobile mast. A whistle costs almost nothing and carries further than a voice.

Then tell someone. Where you are launching, where you are going, when you expect to be back and what you are wearing. It takes a text message and it turns an eventual “they didn't come home” into an early, targeted call to the coastguard. The full version, for any trip, is in our float plan guide; for a paddle, the one-line text is enough.

You Are Invisible Below a Metre

From the helm of a motorboat doing 20 knots with the bow lifted, the water within 50 m ahead is often hidden entirely, and anything that sits less than a metre above the surface disappears into the glitter and chop a few hundred metres out. A kayak is 30 cm high. A swimmer beside a paddleboard is 20 cm. Powered boats are not trying to hit you, they simply cannot see you, and the collision regulations that make you the stand-on vessel are no comfort when you were never noticed.

So be tall and be bright. A paddle blade raised and waved is the single most visible thing you can do; a fluorescent hat, a bright buoyancy aid and a coloured board all help, and a small flag on a mast is standard among sea kayakers for exactly this reason. Stay out of channels and away from harbour entrances, cross them at right angles and in a group, and assume every powered boat has not seen you until it visibly alters course. After dusk, a white all-round light is required on most waters for paddle craft under way and, more importantly, is the only thing that will make you exist.

Personal Watercraft: Throttle Is Steering

A jet ski is the opposite problem from a paddleboard: too much power rather than too little. Two facts about how it works cause most of the injuries.

The first is the kill cord. The lanyard that clips to your wrist or lifejacket and pulls a key from the console shuts the engine down when you fall off. Without it, a PWC that has lost its rider carries on, or circles, at speed, through the water you are now swimming in and towards anyone else nearby. Wear it every time you sit on the machine, even for a 30-second repositioning. Check it actually stops the engine before you leave the beach; corroded switches fail.

The second is that a PWC steers with a jet of water and only when that jet is running. Your instinct when something appears ahead is to let go of the throttle and turn the bars. Do that on a jet ski and nothing happens: the machine carries straight on at the speed it had, unable to turn, until it hits whatever you were trying to avoid. Some newer models add an off-throttle steering or braking assist, but none turns like a boat with a rudder. The rule is to slow down early and keep some throttle on through every turn. Practise this in open water before you need it, and give yourself far more stopping distance than you think is polite.

The rules of the water then follow. No-wake zones exist near moorings, marinas and swimming areas: idle through them, because your wake knocks people off paddleboards and swamps dinghies. Minimum distances from the shore, from swimmers, from divers' flags and from other craft are set by the country, the state or the local harbour authority, and they differ, so check the rules where you launch; figures in the range of 50 to 100 m are common for shore and swimmer separation, and speed limits within a certain distance of the beach are near-universal. Age limits, licences, registration and compulsory training also vary widely, from nothing at all to a mandatory certificate. If you are renting on holiday, the rental company knows the local rules; ask them before you sign.

Wear a lifejacket rated for high-speed use. Towing a tube or a wakeboard, carry an observer so the driver can watch ahead, agree hand signals first, and cut the engine, not just the throttle, when picking someone up: the propeller at the pick-up is the other classic injury.

Launching Toys from an Anchored Boat

The nicest paddling of the year is off the back of a yacht or a motorboat in a quiet anchorage, and it has its own trap. Boats anchor where there is shelter from waves, which often means a headland or a river mouth, which often means current. A tidal stream of 2 knots looks like nothing from the deck. It is faster than most people paddle a SUP, and much faster than any of them swim. A child who slides off a board 30 m astern of the boat in a 2-knot stream is 100 m away in a minute and a half, and the parent who dives in after them is now the second casualty.

A few habits make it safe. Before the first toy goes in, stream a floating line 20 to 30 m long astern with a fender or float on the end. Anything, or anyone, drifting off the back grabs it and is pulled home. Polypropylene floats; your nylon dock lines do not. Watch the line for a minute before anyone goes in: the angle and speed it streams at tells you the current, and if it stands out straight and taut, the water is not for paddling today.

Then: lifejackets on before anyone steps down onto the swim platform, not once they are on the board. A downwind and down-current limit everybody can see (that moored boat, that rock) beyond which nobody goes. The dinghy in the water with the outboard tested and started, so it is a chase boat you can be in within thirty seconds, not a project. And one adult who stays aboard and does nothing but count heads, out loud, every few minutes. Not the person cooking, not the person on the phone. The counting is the safety system; the rest is kit.

The same person also owns the boat. A crowd in the water is a lot of distraction on the one afternoon the anchor chooses to drag. If you are staying the night, the way you anchored in the first place matters too; our overnight anchoring guide covers the setting and the watch.

One Person Watches the Water, the Alarm Watches the Anchor

When the toys are out, the person left aboard has two things to watch: the heads in the water and the position of the boat. The first needs eyes and cannot be delegated. The second can be. A GPS anchor alarm on a phone or watch, set with a radius around the anchor before the first board goes in, will tell the watcher the moment the boat starts moving out of its swing circle, so they can keep their eyes on the water and their attention on the count. It does not replace the person. It gives the person back the part of the job a machine does better.

The Bottom Line

The small craft kill people because nobody thinks of them as going to sea, and the sea does not make the distinction. Wear the buoyancy aid. Match the leash to the water and never wear an ankle leash in current. Keep a way to call on your body and tell someone where you went. On a jet ski, wear the kill cord and remember the throttle is the steering. From an anchored boat, stream a line astern and count heads. And above all, before every paddle, look at the wind: the danger on a paddleboard is not the water you are on, it is the wind you cannot feel. An offshore breeze is a one-way ticket, and the time to notice is on the beach.
