When Kayakers Are Rescued at Sea

A pair of former sea kayak instructors, rescued by the Coast Guard while paddling in heavy seas and moderately high winds off the US's Plum Island, Massachusetts wrote a lengthy trip report about their experience.

They were paddling the Plum Island area of Ipswich, a shoaly area that faces northeast, towards open sea.

Conditions that day were onshore: wind pushing heavy waves and steep chop towards the beach.

During the rescue, the two were basketlifted out of the inshore shoals by a Coast Guard helicopter deployed from an air station about 45 miles away. The two decided to call for help after both paddlers both capsized and one failed to roll up, losing his boat in the process. Water temps were normal for early spring in Massachusetts: about 52-degree (F).

Both were in the water nearly two hours before they were located and rescued. The Coast Guard and Ipswich harbormaster were both on scene.

Because the Coast Guard surf boats couldn't reach the kayakers in the shallow water and violent surf, there came the arrival of rescue swimmer Derrick Breton, hoisted down from the helicopter.

The guys were pretty embarassed. But they were well prepared.

What's noteworthy about the rescue is that though the paddlers' judgment is open to all sorts of second guessing, they were well-prepared when they set out. They had enough flares to light off nine. They wore drysuits, neoprene hoods, had decklines, and each carried a VHF radio.

That both kayakers were carrying VHF radios was crucial: one radio's batteries crapped out pretty quickly.

Similarly the kayakers were prepared for cold water immersion. Both wore GoreTex drysuits. Both wore hoods, fleece and neoprene gloves. Just as important their kayaks were equipped with decklines.

The paddlers clung to one boat while they awaited rescue. The other kayak, torn away by the surf, was later recovered on Plum Island by the harbormaster.

EPIRBs Part 4: Longevity, Reliability, Durability

This from Mark Tozer, who writes about sea kayaking from the UK; Ofcom is where Brits, whether commercical or recreational concerns, reigster their PLBs and EPIRBs:

A ship's distress signal has been traced to a mountain of scrapped fridges and TVs in Belfast. A team from broadcasting regulator Ofcom found the beacon after the mayday was picked up by Civil Aviation Authority Receivers on the Isle of Man.

Normally a rescue helicopter is scrambled when a distress signal is picked up, but RAF Kinloss could tell the signal was on dry land. The beacon activated after it had been dismantled from a vessel. It was tracked by satellite from a scrap-metal yard in north Belfast last week as it was moved by lorry to one in Queen's Island in the docks area.

The beacon was found in the middle of a 20ft pile of old electrical equipment. Philip Morgan, spectrum manager for Ofcom Northern Ireland, said the device had to be found and turned off because it interferes with the CAA's radio system.

"It was a bit like looking for a needle in a haystack, but using our radio tracking equipment, and with the help of the scrapyard's crane, we were able to find the beacon very quickly and disable it - within a couple of hours of it going off."

Ofcom Northern Ireland investigates about half a dozen cases every year of distress beacons from ships or planes being
activated accidentally. Mr Morgan said the devices, which can go on for a considerable length of time, had to be disposed of responsibly. "Otherwise they can cause a false-alarm which wastes the rescue services' time and could divert them from a genuine emergency," he said.

The Farallon Islands (US): Dreaming of Sharks

Above: detail from Copley's 19th-century canvas Watson and The Shark. Copley made three copies of the large (6' by 7.5') painting. One hangs in Boston's Musuem of Fine Arts, the larger original in the National Galllery in Washington, D.C.

Great white sharks are a commonplace in the waters around the Farallone Islands of Northern California (about 27 miles west offshore of San Francisco) (read more about the Farralones in an earlier post). John Singleton Copley was primarily a much praised, then as now, portrait painter before he painted the canvas above.

Watson and The Shark brought Copley international fame and great critical acclaim. The canvas has been interpreted in various ways - a comment on man's better humanity, a comment on God's fury, a demystification of nature as much capable of violence as capable of the sublime.

The painting addresses the most primal human fear: that of being eaten alive. There's a long backstory to the painting, based on true events, that I'll add later.

Watson was a 14-year-old boy when he was attacked by the great white while swimming in Cuba's Havana Harbor. He lost a foot and part of a leg in the attack. In adulthood he went on to become mayor of London, then a baronet. Parodies of him as a politician quipped that Watson would have been a more effective legislator had the shark lopped off Watson's head rather than than his foot.

Not long ago Time magazine writer Susan Casey (free downloadable mp3 recording) spent time on the Farallones, a visit that led her to write The Devil's Teeth.

If you have time, give the excerpt of her book below a read. Just keep in mind that it was written for the slower digestive tracts of print....and that if you skim reviews of the book on Amazon, pillories vs. praise come out at about 50/50:

From The Devil's Teeth:

As the light came up and I stepped outside I saw that the fog had dissolved, the ocean was unveiled, and the jagged contours of another Farallon, Saddle Rock, were crisply in focus for the first time since my arrival.

Saddle Rock reared out of the water only two hundred yards southeast of the main island, and from certain angles it looked exactly like a dorsal fin. Cormorants bunched along its edges, forming an elegant black picket fence. It marked the divide between Mirounga Bay (where the Rat Pack hunted) and Shubrick Point (where the Sisterhood reigned). Many an elephant seal head had been lost in its shadow.

Scot and Peter and I drank our coffee on the front steps, looking out at the water glimmering in the early light. There was a feathery wind and a handful of scudding clouds.

The morning was hardly tranquil, though. The gulls screeched at top volume, as always. Surf boomed onto the rocks and the air was hazy with spray. Seabirds flew formation passes over the water, and every time they seemed to favor a particular spot I felt a little flash of hope -- was there a carcass out there? Peter seemed to have other things on his mind; he was eyeing a perfect eight-foot barrel wave that rolled along an area known as "Shark Alley." The wave, unsurprisingly, had never been ridden.

Not for lack of surfboards, though. There was a quiver in the supply shed at all times -- Scot used them as decoys to lure sharks to the surface for photo IDs. To a shark, apparently, a nice little six-foot swallowtail does a near-perfect imitation of a seal. When retrieved, the decoys were often missing hubcap-sized chunks from their sides, and surfers had taken to sending Scot their castoffs, hoping to repossess them after the sharks had paid a visit. Along with their research value, the strafed boards made for great conversation pieces.

According to Scot and Peter, the Queen Annihilator of Surfboards was a shark named Stumpy. Stumpy was nineteen feet long and weighed five thousand pounds, and when she was in residence, she ruled the Farallones. "She was the only shark that I think understood who we were, what we were trying to do," Peter recalled. "And she didn't care for it. When Scot was first putting out the decoys Stumpy would just come up and destroy them, more because she didn't like them than because she was fooled by their silhouettes." He turned to Scot. "Hey, it's an odd-numbered year. Stumpy could be here."

"If she was, we'd know it," Scot said.

Stumpy patrolled a swath of sea along the east side of the island near the main boat launching spot at East Landing. For prey, this was not an advisable route onto shore. "No seal gets by her," Peter said. And while other sharks would take twenty minutes or more to consume their kills, Stumpy could polish off a five-hundred-pound elephant seal in three minutes flat. Though the distinctively cropped tail fin that earned Stumpy her name hadn't been spotted for several years, Scot and Peter still talked about her with a respect that bordered on awe.

"Stumpy was a goddess, there's no other way to put it," Peter said, lowering his voice in reverence. One time, Scot rigged a video camera on the underside of a surfboard to determine which angle the sharks were coming from when they attacked. He set the video board adrift off East Landing. Right on cue, like some battle-hardened test pilot, Stumpy gave it everything she had. The resulting footage was stunning, all teeth and whitewater and violent smashing noises that brought to mind a subaquatic train wreck. It was the first time anyone had successfully filmed great white sharks underwater in California.

Stumpy made her movie debut in the BBC documentary I had seen, and won Scot an Emmy for cinematography. During the first furious hit the board snapped in two and shot into the air, and as the camera dispassionately recorded the wreckage, Stumpy resurfaced and gave the bobbling pieces a fierce backhand with her tail, before swimming off grumpily in search of real food.

None of this seemed like the best testimonial for the sport of surfing.

And yet everyone involved with the Shark Project surfed. In fact, Brown had actually been attacked by a shark while riding waves in Palm Beach last November.

"Yup, I'm a statistic," he admitted the night before when I asked for details. "I wouldn't say I was attacked, though. It's more like I was bitten."

By seventy-six teeth, to be exact. Waiting for a set, Brown had felt some pressure on his foot and looked down. All around him the water was red.

Holy shit! Look at all that blood, he thought, not quite realizing it was his own. He never saw the shark, but after examining his wounds he concluded that it was a sand tiger, a spooky-looking, snaggletoothed shark that eats fish. And in the turbid Florida water, flashing white feet can look an awful lot like fish.

Peter grew up as a surf rat on the beaches of Oahu. Every day after school he'd run to grab his board, a hulking ten-footer that he'd bought for four dollars at a garage sale. (The deal might've had something to do with the board's sky-blue patina of lead-based paint, which would chip off and lodge under Peter's toenails.)

Even as surfing gear improved and evolved over the years and his friends began to do flamboyant tricks on the new shortboards, Peter always preferred the big logs. Longboarding was more soulful, he felt, more in tune with the ocean. Whether other surfers agreed with these esoterics or not, there was at least one advantage to a larger board: It didn't look quite as much like a seal. (Boogie boards, apparently, were the worst.)

"I know exactly how I'd do it," Peter said now, gesturing toward the wave. "But to get into the water here . . ." His voice trailed off.

"Well, maybe you could try it in April," Scot said.

Shark attacks in the spring were rare. Even so, he didn't sound too convinced. He had only recently taken up surfing, and was openly cautious about wave selection. With good reason. While the Farallones provided a convenient drive-thru for seal-hunting sharks, it was certainly not the only place around here where you'd think twice about getting on a surfboard. All of Northern California is sharky, so sharky that the area extending from Tomales Bay in West Marin County to the Farallones to Monterey is known as the "Red Triangle." More attacks by great whites had taken place in this pocket region than in all the other shark hot spots of the world -- combined. Close to home near Inverness, there were a handful of surf spots that Scot wouldn't even consider.

"North Beach and South Beach," he said. "I won't go there." These beaches were just north of the Point Reyes Lighthouse and featured nearby elephant seal colonies. Both areas had strong undertows and rogue riptides and wonderful ambush potential and, of course, seals, all of which add up to precisely the type of arrangement that great white sharks like. There was also an ominous place near the mouth of Tomales Bay called Shark Pit, where surfers had recently encountered three white sharks in a single day. Concerned, one of them asked Scot, What's going on? Had there been a sudden influx of seals? Was it the full moon? The red tide? The new yellow wetsuit someone was wearing?

"Nah, they're usually there," he told them. "You guys just saw 'em."

"I don't surf where there are sharks," he emphasized to me now.

"You surf in Bolinas!" Peter said, with a snort. Bolinas was a tiny beach town, also in West Marin, that was only eighteen miles by boat from the Farallones. Sightings of healthy-size white sharks in the town's channel were not uncommon. Recently, a boogie boarder had been attacked there. In other words, Bolinas had plenty of sharks.

"Yeah, but I'm in water that's only up to my chest," Scot replied, laughing. "And I always have a buffer zone of about fifteen kids around me."

All this shark talk was making me impatient. Where were they? As if reading my mind, Scot suddenly stood up. "There's something going on down there," he said, pointing toward the wave. Even without binoculars I could see the black dorsal fin, it was that close to shore; any closer and the shark would be joining us for coffee. We watched for a moment as the fin carved a few tight circles like a figure skater diligently practicing and then disappeared into the surf.

"There's no carcass," Peter said.

"Yeaahhh, that's just one of them being weird," Scot said.

"Well, it could be a sea lion, though." Sea lion carcasses don't float like elephant seal carcasses. Thus, attacks on sea lions were much harder to spot. It was decided that we'd launch the whaler and take a look; even if there was nothing going on in Mirounga Bay, we'd be out on the water, that much closer to the action.

The Farallon Islands (US): video



Above: An introduction to California's Farallon Islands. Remote, foggy, wondrous and strange.

The video features Kenny Howell. The islands lie 27 miles off San Francisco and are home to, among other creatures, a large white shark colony and several pods of whales.

Some of the island group's wonders don't all have to do with the natural. Offshore, deep, remote, and virtually unknown to most, it was a convenient dump site for radioactive waste materials from the Livermore Nuclear Labs.

Above: shark-feeding blood spot at the Farallon Islands. Flickr photo.

During nuclear weapons testing at Bikini Atoll prior to the end of WW II, ships in the area irradiated by the blasts were towed here and sunk. The aircraft carrier Independence lies sunk here, as do some 47,000 barrels of radioactive debris, according to research being conducted by the USGS.

Facts on what was dumped around the beautiful and intimidating Farollon Islands come from the The Center for Land Use Interpretation.

The islands are now a National Wildlife Refuge (Los Farallones) staffed by researchers and Coast Guard personnel.

If I've got my facts straight, Kenny is a California surf skier and ranking member of the international surf ski racing community.

Surf Ski Racing: At the Starting Line



Above: the start of a recent surfski race at Amanzimtoti Beach, Durban, South Africa. The longer you watch the more intriguing and impressive the video becomes and, at least to me, the more surreal.

Nowhere on the planet, I think, could you find in the same place that many sea kayakers who handle conditions like these.

For one, there's no place in the world where that many sea kayakers have gathered in one place...at least as far as I know.

As for there being that many sea kayakers in the world who could handle a beach break of that size...well that's a whole 'nother set of assumptions.

The video comes from the ever-helpful Rob Mousley at surfski.info.

Beginning Surf Skiing: Video



Above: beginning surfskiers head out on calm waters to learn balance, stroke fundamentals, etc.

Note how twitchy the surfskis are, and how their waterline length (wl) and length overall (loa) are for all practical purposes identical.

The design -- wl = loa -- is typical of non-planing boats built to maximize hull speed: the longer the waterline, the faster the boat.

You see the same shape - plumb bow, plumb stern, almost no overhang at bow and stern - on modern ultralight ocean-going racing sailboats like those shown in the video and still image below.

You see that design most noticeably, on two stitch-and-glue kayaks, the Paxes, from Chesapeake Light Craft [link forthcoming].

Problematically, however, the relation of width to length of one of the Paxes renders it invalid for certain racing classes.



Above and below: video and still photo showing the plumb bows and sterns of ocean racing yachts whose shape pedigree (swede-form, or skinny up front, wide towards the stern) mimics the shape of surfskis. One key difference is that these large and light, ultra-stiff boats also plane.
Interestingly (at least to me) the shape of both surfskis and transocean ultralight racing sailboats harkens back to that of World War I battleships.

Below: planing in the extreme. Rigged with spinnaker, bowsprit, trapeze and outriggers, an open transom Musto skiff leaps up the face of tiny swell while planing. Note daggerboard maintaining minimal contact, much like a sailboard skeg, with water midships:

Some Surfski Basics: Be Safe and Go Fast

Above: the engine compartment of a surf ski. Note the beckson hatches, rudder peddles, and the cockpit's molded-in thigh lift/pelvis drop plane (just above the H in Huki) similar to the shape many sea kayakers mimic with closed cell foam seats [link].

Surf skiers from South Africa, the US (Connecticut and Maine) and Naimano, British Columbia have been helpful in getting me up to speed on the nuances of their sport as it's practiced throughout the world.

Here are a few of their basic points.

Surf skis are remarkably long and fast, and their open cockpits don't deter anyone anywhere, regardless of how cold the water.
Above: Kathleen P. of Canada straps on what most sea kayakers would probably regard as heresy: a leg-to-boat strap not much unlike a board surfer's ankle strap. When a surf skier capsizes, last thing he or she wants to do is lose contact with their boat.

As one surf skiing commenter put it, sea kayakers tend to focus too much time learning how to stay out of the water. Pool and skill sessions typically involve practicing group and paired rescues or by learning the difficult-to-some skill of rolling.

And why not? Often sea kayakers are out for more than a day at a time, in water far from home. Capsize a kayak and there's no quick fix to getting dry and upright. Hence rescues like the hand-of-god, bow-roll, etc. (links forthcoming).

Surf skiers, on the other hand, take immersion as a way of life. Their kayaks are tippy (that the are so narrow and long makes them fast: up to a point, in naval design, the longer the boat, the faster.)

Below: Kathleen opens the beckson hatch [link] cut into the transom of her surfski's foredeck. Inside she'll store a platypus [link] filled with water. To paddle a surfski fast, you need a wing paddle and lots of water, not only to skim across but drink.
Below: like any wise watersports enthusiast, Kathleen dresses for immersion. In places like South Africa or Southern California, you don't need to wear much. But in British Columbia, Canada, you do. Kathleen wears a set-up any sea kayaker will recognize: neoprene farmer jane and a paddling jacket.

The straddle is one way to stabilize a surf ski while gearing up. The position is also to crux to a self rescue. Note the broad flats and hooked edges of Kathleen's carbon fiber wing paddle.

Below: a typical surf ski cockpit. I found that a surfski, like a tender kayake in rough seas, is more stable when moving. Each dip of the blade stabilizes on side of the surf ski, then the other.

This is a fairly important distinction. Although skilled surfskiers can handle wind and waves that would send many sea kayakers back home, surf skis have no inner gunwales, nor underside of the foredeck, to create stabilizing pressure with by use of the knees, thighs or hips.

Note the surf skis foot peddles. Kayakers accustomed using footpegs to create torque and torso rotation will find a surk ski's peddles tricky. They control the surfski's mandatory rudder. To create torso rotation pressure with them, you need to apply equal pressure to both.

Also note that a surfski doesn't have a backband - which would interfere with torso rotation - but, rather, an integral pillar whose function would be familiar to anyone whose torn out their sea kayak's seat, replaced it with a foam core pleasure pod, and replaced the backband with a pillar [links forthcoming].

Finally note that most surfskis are swedeform, or narrower at the bow, wider midships and aft.

Sailing a Kayak Solo

Below: another, perhaps better view of solo kayak sailing, in this case in Greece. Again a masted, self-stayed sail. The paddler truly rips along. You'll note that the boat has a rudder and that the sailor/kayaker uses long-held low-brace leans and the occassional bow rudder to control and steer the boat:
The video above, from seakayakgreece.com, was taken in force 5 winds (17-21 knots, or what's referrred to as a fresh breeze), during a fast downwind leg off Milos Island, Greece. Note the paddler's use of a port bow rudder. As I watched the video I wondered from time to time what it would be like to attempt a roll with a sail on the foredeck.

Milos Island lies off Greece on the Aegean Sea. The island is part of the Cyclades, a large island group southeast of the Greek mainland and about 86 nautical miles from Piraeus, or about half way to Crete.

One of the issues with sailing a kayak is discomfort.

The discomfort issue is not so obvious. The surest way to develop some pretty severe back and leg pain, or worse, sciatica, is to sit motionless in your kayak for too long.

The reasons for that are fairly numerous. All of the sitting pressure we ordinarily transform into torque to propel the boat by paddling from the core clots, inert, in the lower back and lumbar area.

Also the alternating foot pressure we create against the footpegs to add more power to our strokes is subsumed within the lower back, hips, and lumbar.

Above: a sailed kayak at it solo. Note that the sail is masted (think of making a peace sign with your index and middle finger inside a sandwich bag) but self-stayed (doesn't require stays held by the paddler or the paddle). The sail is tall and narrow, has a clear window, and moves the kayak along at a pretty good clip. The sail has important distinctions from the sail shown in the post below, not all of them as obvious as the differences in the sails' sizes, shapes, and height from deck.

Finally we lose the lower body mobility we create as we shift our weight and use knee-hangs against the inside of the foredeck for control and balance -- that veritable improvised jazz tune of weight shifts, knee pressure changes, leans and so on we use to keep the kayak upright.

So sail a kayak and a couple of things happen. You blast downwind at speeds that easily top out at your kayak's hull speed, typically the speed it would attain if surfing.

Second, you do what you can to steer the kayak with a rudder or any number of braces, leans, and rudder moves bow and stern.

But essentially you sit locked in cement in the too-small bathtub that is your cockpit. But boy do you go fast.

Which brings up a sail's utility for the solo paddler. Sailing your kayak turns it into a boat.

On long journeys where you need to make mileage, a large increase in average speed can do wonders for your dailies. Should you be injured, ill, or under pressure to accomplish other tasks while keeping moving (resting, running a vhf radio or satellite phone), you continue making miles.

But the bottom line is that sailing a kayak can make us better paddlers with higher levels of sea skills. The nuances of wind -- its shifts in direction, speed, gustiness, or tendency to shift during certain seasons and times of day -- are all too often lost on kayakers for whom kayaking marks their first exposure to the maritime environment.

If we learn to sail our kayaks, we have that many more skills and types of knowledge.

By learning to sail a kayak we learn and know that much more about the force - the wind - which more than anything affects the type of day we'll have.

Sailing a Kayak Pod



Above: this from youtube, showing a small float-and-bloat fleet (a prevalent guides' term, not mine) pulled along by a large sail simple enough, and with enough stay points, to motor the pod with the ease and grace of a swan.

The video was taken in New Zealand's Doubtful Sound, in southwest New Zealand's famed Fiordland National Park not far from Queenstown,

For more on kayak sailing, wait for a handful of subsequent posts, including a review of a new kayak sail from Hood River, Oregon, the WindPaddle.

Kayak sails are quite fast downwind and have valuable applications in any group that shows a tendency to spread apart with the varying speed abilities and downwind skills of its members - in other words, all large groups.

Short view is that a pod equipped with sails is a tighter, more proximal group.

Long view is that kayak sails are easy to use, generate lots of speed, don't cost much, and for long-haulers intent on mileage, keep a kayak moving even while you eat lunch, cook food, read a book, take a nap or solve on the foredeck some thorny navigation problem.
