Author’s Note: The following story covers the first three months of 1999. On the 1st of January of that year, we set sail from Colombia aboard the 65 foot balsa raft, Manteño II. We had spent the previous months on land, rebuilding the raft after parasites, called “shipworms,” had badly damaged the vessel’s logs.
We set out for Panama, expecting to continue on to Mexico. For eighteen days we tried to stay near land—near the Central American coast—but were driven out to sea by erratic winds and currents. After sailing to within five miles of shore, we were sucked into The Gyre, a naturally occurring whirlpool, 600 miles in diameter. Inside The Gyre, there is no wind.
Aboard the raft were four men: Alejandro and Cesar, the two Colombians who had volunteered to sail with us while we were rebuilding the raft, Martin, the cinematographer, and myself.
The Dangerous Voyage, Episode 3: The Sea Snakes and the SharksOn one calm evening in The Gyre, Alejandro went out on watch, and while making the rounds, stepped on a sea snake. Miraculously, it didn’t strike him, but it was now clear to us that the snakes would be coming on board at night. It was no surprise; The Gyre was infested with them.
Sea snakes are exceedingly poisonous. Their venom is a neuro-toxin, stronger than that of the king cobra, which paralyzes the victim that has been bitten so that, slowly, respiration becomes impossible. There is only one company in the world that makes an anti-venom, and it is in Australia. Thankfully, they are not usually aggressive. Most human deaths come from fishermen accidentally running across them in fishing nets. Occasionally, however, there are sightings of “thousands” swarming in one area.
Bright green and yellow, the sea snakes around Manteño II averaged about three feet in length, were very slender, and had a flattened tail, like a rudder, perfectly developed for swimming in the ocean. They usually swam on the surface of the water, slithering along in the same motion as a snake would move across the land, wiggling in a serpentine fashion to propel themselves, but when startled, they could kick with their tails and shoot through the water like a spear.
A few days before Alejandro’s encounter, I had sent Martin over the side to reset the starboard stays on the foremast. He went through the usual, arduous, surfacing and diving, pulling and fighting, and then a sea snake suddenly shot forward from the stern. It stopped and hovered on the surface above Martin, who was below and about to come up. In a split second I envisioned Martin surfacing right under the snake, it hanging off his head like moss, Martin convulsing in fear, and the snake reacting by striking him. With nothing else to do, I grabbed my boot off the top of a water barrel and threw it, and instead of scaring the snake, the boot hit it. For a moment the creature was stunned, but then it came-to and so I threw the other boot and it took off, swimming away from the raft right at the same time Martin’s head broke the surface. “Martin!” I screamed, “Dive! Dive down! Go back under!” It took him a second to realize what was going on, then he pushed off the logs in a sudden panic and dove back under the surface. By that time the snake was ten feet away and the danger was gone, but Martin seemed to cling to this incident, and convinced himself that I had “saved his life.”
“I just threw a boot.”
“Were those your last shoes?”
“Well, yeah.”
“I’ll buy you another pair of shoes, if we ever get to land.”
I was now barefoot. Soon, my feet began to bruise and swell painfully from walking on the bamboo deck, just as they had during the voyage of the Illa-Tiki.
We began wearing our rubber jungle boots or other foot gear on watch at night. Nevertheless, using the bathroom off the back logs was especially unnerving, because it usually required taking the boots or shoes off: In the darkness, if the sea was up, you felt masses of warm seawater flood up to your hips as waves came in, then the sudden sucking of the water receding away, like a beach surf. After the water was gone you stood there in the darkness, motionless, waiting to detect the clammy slither of a sea snake across your ankles.
Each day, during this time, Cesar maintained a sharp lookout for sea snakes. He yearned, always, to catch one. As one of The Inventors he had fabricated a personal snake tender: a stick, about three feet long, with a loop of string at one end that could be tightened around the snake’s head. Once the tender had been made, Martin wanted to get Cesar on film, catching a sea snake, and it didn’t take long to spot one. At 3:30 one afternoon a snake came along the port beam, glanced off the logs, and then started swimming away from the raft. Launching the inflatable dinghy, we paddled out after it. Cesar sat up on the bow while Martin and I paddled. We pursued the snake for a hundred yards, seeing it and losing it several times. After losing it for the last time, we turned back, and when we did we were amazed by what we saw. The sky had changed since we had left the raft, fifteen minutes ago. A vast rain shower was coming over the horizon, and we were taken aback by its beauty. The sun, which was on the opposite horizon, gleamed a brilliant silver reflection on the wall of falling water in the eastern sky. It was the greatest demonstration of the color silver that I have ever seen. It was a gleaming waterfall of nature, twenty miles wide, reaching from the sky down to the surface of the ocean, curving over us like an enormous band shell. It seemed to emanate light—to produce light—rather than to reflect it. We could see its entire size and shape because it was so far from us, but we could also see the tiny, individual drops, floating down to earth. It was twenty square miles of cool, trickling, silver leaf, but alive, and moving. It was the most beautiful vista of my life.
“What does it mean?” Martin asked.
It was not a question, but something he pondered. What did it mean? If the ancients saw this as a sign, then I must sympathize. I am a man of reason, but this moment shook me. This immense beauty, this silver utopian vision, had no reason. Only a meteorological phenomenon? Perhaps. If a logical explanation can be found for how it occurs, which it can, then I am still forced to ask, as Martin did, What does it mean? Why would such beauty exist? I assign no religious implications to this moment, but I do ask, Why?

On the 27th and 28th we discovered Teredo navalis shipworms in our balsa logs. It was such a dark subject inside my mind that it was hard to accept that we were, once again, going to sink. Many options lay before us, of which the most attractive was the construction of a new raft, while on the high sea. By the 30th of January we had drifted 400 nautical miles from Montuosa Island, our last sighting of land. As we went farther out to high sea, the size and abundance of marine life increased. We sighted more sharks, although they were still skittish.
At 2:00 am on the morning of the 2nd of February, we were hit by our first Chubasco. A Chubasco is an exceedingly concentrated rainstorm, indigenous to Costa Rican waters. Water poured into the hole in the roof where the mizzenmast jutted through, and in a three-hour period we collected 80 gallons of fresh water. I made a note in my diary that everyone on board was calm during the intense downpour. On the next day, I wrote in my diary:
3, February, 1999
“I find colonies of Teredo navalis. (I) am plagued by dark fears again. Can’t tell if the raft is sinking (quickly) or not.
“The course is starting to change for the worse - more north than west. Martin is a fanatic about fishing. My admiration for Alejandro and Cesar continues to grow.”
4, February 1999
“Moving east now - (trapped in The) Gyre.”
We were rounding our third orbit of The Gyre. The mast stays were beginning to chafe and wear. They would have to be changed and reworked. Also, about this time, large sharks appeared around the raft.
Shark attacks on the fish we caught were a frequent occurrence now. Martin would go into the water and spear a fish, only to have the sharks swoop down and bite it in half. The smell of blood and the frantic flapping of fins at the end of the spear were like setting off an alarm. The sharks sensed that the killing was easier near the raft and homed-in. The moment the harpoon would penetrate a fish the sharks would bolt through the water like bullets, sometimes two or three at a time, and gobble it up so fast that it seemed as though it had disintegrated. It chilled Martin. “Man!” he said one day, after clambering aboard the raft for safety, “They attack the second the harpoon goes in! You should see them!”
The sharks were becoming an issue, and we could no longer ignore them. We worked under the raft everyday, setting and resetting the pontoons, reworking the tourniquets, and tightening and resetting the mast stays. The sharks liked to examined us while we worked by passing close to our faces: You’d be working underneath the raft with your hands over your head, holding your breath, struggling to untie a knot, focusing all of your attention on a small area, when a gray shark—its mouth open and its eyes twisted in an evil and uncoordinated fashion—would cruise by just inches from your mask. It startled you, like turning on the light in a dark closet and discovering an intruder staring at you with a knife in his hand. Just this problem alone was a serious hindrance because it broke down our ability to concentrate on repairing the raft, but we faced a more serious problem than just our natural human fear of sharks.
The problem that we faced was not the size of the individual animals but the number of animals. We rarely saw any sharks that were larger than eight feet and never any that were over 100 pounds, so we didn’t fear an outright killing, where a large animal would come in and make such a horrific attack that one of us died quickly from massive tissue loss and trauma. That scenario was highly unlikely. What we feared was their behavior as a group. When there is blood in the water, combined with the flapping sounds of wounded fish, sharks tend to be far more aggressive than is normally the case. If these two conditions, blood and sounds, occur where sharks are schooling in great numbers, their behavior becomes highly reckless, and hundreds upon hundreds of sharks now orbited the raft, singly and in packs, randomly attacking anything they could.
We separated into two camps, the Shark Police and the Worker Bees. Alejandro and Martin, both of whom were quite understandably nervous about sharks, would work on whatever was needed, while Cesar and I, who couldn’t help but be fascinated by the sharks, would police the waters by patrolling with spear guns and hand harpoons. Typically, when there was a lot of work to do, Cesar and I went in first, to clear the area. Upon entering the water we’d immediately make a quick scan of the water, spinning our bodies around, squinting through our masks at the community of sharks. Invariably, several groups of five or six cruised together, slowly swimming circuitous routes around the raft. Whenever a pack was nearby we could see every detail of their muscular gray bodies and triangular tales waving lazily in the clear water. Occasionally there would be a large one, swimming alone and waiting for its chance. Then there would be the packs several hundred feet away, cruising at the far periphery of our underwater vision like languid phantoms in a blue, opaque fog.
We developed a method for chasing sharks away from the raft that was crude but effective: Cesar and I would speed toward the nearest school, motoring through the water on our fins. We’d hold our harpoons in one hand, pressurize our ears with the other hand, and then dive. We’d come in fast, fins flailing, our masks compressing around our faces, and then, at the last second, we’d widen our mouths, push on our diaphragm, and scream psychotically while jabbing a shark sharply with the harpoon. Even though we rarely pierced their tough skin, they always went scurrying away. Occasionally they’d turn and snap at the harpoon, but that was clearly out of panic, not because they wished to fight with us. After a while we learned to attack the sharks when they were in their most vulnerable positions: We’d come in from above and behind them and jab them sharply in the back, an area that they could not easily defend. This was highly useful because the sharks seemed to possess a somewhat communal nature about them: Generally speaking, each individual shark kept an eye on everything that was going on in the community. Whenever we made an attack on one of them, most of the others seemed to take notice—they would jump as though startled, or would suddenly begin swimming much faster than normal. This made dispersal much easier because most of the other sharks nearby would clearly register the fact that something had attacked one of their own, and would begin to clear out, leaving for better grounds. They were ‘dumb animals’ and we were, essentially, bluffing them—making them believe that we were in charge of this area and that they had to leave. They seemed to have a short memory though. A pack would scurry away after an attack, disappear into the ocean, then slowly reemerge a few minutes later, materializing out of the infinite blue, looking for new opportunities to eat. It frequently took repeated attacks on one particular school to drive it away permanently.
Meanwhile Alejandro and Martin would work on the raft. Now, with all four of us in the water, all of the action would be going on under the surface. If you’d have come upon Manteño II during this time you’d have thought the raft abandoned. But underneath, looking through the glass of my mask, I’d see two men, working underneath the raft, their arms and hands over their heads, struggling and pulling on the thick manila lines, holding their breath and treading water with their legs. Their black flippers would stab at the water in slow motion and the black, rectangular shape of Manteño II would hover motionless above them while sharks circled all around in the rich blue infinity. Cesar, muscular and compact, would be off to one side, scanning the water, working his arms furiously, spinning his body round and round, watching for sharks. We’d hand-signal each other and then suddenly surface into the air and the clattering, splashing noises. He’d spit out his snorkel and yell, “How are we doing John?”
“I… I think we’re OK. What happened to that big one in the back?”
“I got him. He left.”
“OK. Let’s go around front.”
Then we’d be back under, breathing through our snorkels, sucking down little drops of brackish saltwater, scanning the silent world for streamlined gray forms, cruising smoothly in the blue. I’d sight one coming in too close, signal Cesar, surface, blurt out instructions for attacking it over the splashing noises, and then we’d go to work. What irony: Cesar and I liked the sharks, yet we were assigned the unfortunate task of attacking them. In all the time we fought the sharks, neither Cesar nor I were ever convinced that they were mean, predatory villains; they impressed us more as dim-witted scavengers. Nevertheless, we maintained a healthy respect for them. We had seen them bite clean through the same fish that it had taken us a full minute to cut through with a sharp machete. If a shark bit one of our crew in this way it would probably sever a major artery in one of our limbs. We stood almost no chance of saving a man with that kind of wound.
