But then one night the short wave suddenly broke through, and Torstein’s call signal was heard by a chance radio amateur in Los Angeles who was sitting fiddling with his transmitter to establish contact with another amateur in Sweden. The man asked what kind of set we had and, when he got a satisfactory answer to his question, he asked Torstein who he was and where he lived. When he heard that Torstein’s abode was a bamboo cabin on a raft in the Pacific, there were several peculiar clickings until Torstein supplied more details. When the man on the air had pulled himself together, he told us that his name was Hal and his wife’s name Anna and that she was Swedish by birth and would let our families know we were alive and well.
It was a strange thought for us that evening that a total stranger called Hal, a chance moving-picture operator far away among the swarming population of Los Angeles, was the only person in the world but ourselves who knew where we were and that we were well. From that night onward Hal, alias Harold Kempel, and his friend Frank Cuevas took it in turns to sit up every night and listen for signals from the raft, and Herman received grateful telegrams from the head of the U.S. Weather Bureau for his two daily code reports from an area for which there were extremely few reports and no statistics. Later Knut and Torstein established contact with other radio amateurs almost every night, and these passed on greetings to Norway through a radio “ham” named Egil Berg at Notodden.
When we were just a few days out in mid-ocean, there was too much salt water for the radio corner, and the station stopped working altogether. The operators stood on their heads day and night with screws and soldering irons, and all our distant radio fans thought the raft’s days were ended. But then one night the signals LI 2 B burst out into the ether, and in a moment the radio corner was buzzing like a wasp’s nest as several hundred American operators seized their keys simultaneously and replied to the call.
Indeed one always felt as if one were sitting down on a wasp’s nest if one strayed into the radio operators’ domain. It was damp with sea water, which forced its way up along the woodwork everywhere, and, even if there was a piece of raw rubber on the balsa log where the operator sat, one got electric shocks both in the hinder parts and in the finger tips if one touched the Morse key. And, if one of us outsiders tried to steal a pencil from the well-equipped corner, either his hair stood straight up on his head or he drew long sparks from the stump of the pencil. Only Torstein and Knut and the parrot could wriggle their way about in that corner unscathed, and we put up a sheet of cardboard to mark the danger zone for the rest of us.
Late one night Knut was sitting tinkering by lamplight in the radio corner when he suddenly shook me by the leg and said he had been talking to a fellow who lived just outside Oslo and was called Christian Amundsen. This was a bit of an amateur record, for the little short-wave transmitter on board the raft with its 13,990 kilocycles per second did not send out more than 6 watts, about the same strength as a small electric torch. This was August 2, and we had sailed more than sixty degrees round the earth, so that Oslo was at the opposite end of the globe. King Haakon was seventy-five years old the day after, and we sent him a message of congratulations direct from the raft; the day after that Christian was again audible and sent us a reply from the King, wishing us continued good luck and success on our voyage.
Another episode we remember as an unusual contrast to the rest of the life on the raft. We had two cameras on board, and Erik had with him a parcel of materials for developing photographs on the voyage, so that we could take duplicate snapshots of things that had not come out well. After the whale shark’s visit he could contain himself no longer, and one evening he mixed the chemicals and water carefully in exact accordance with the instructions and developed two films. The negatives looked like long-distance photographs—nothing but obscure spots and wrinkles. The film was ruined. We telegraphed to our contacts for advice, but our message was picked up by a radio amateur near Hollywood. He telephoned a laboratory and soon afterward he broke in and told us that our developer was too warm; we must not use water above 60° or the negative would be wrinkled.
We thanked him for his advice and ascertained that the very lowest temperature in our surroundings was that of the ocean current itself, which was nearly 80°. Now Herman was a refrigerating engineer, and I told him by way of a joke to get the temperature of the water down to 60°. He asked to have the use of the little bottle of carbonic acid belonging to the already inflated rubber dinghy, and after some hocus-pocus in a kettle covered with a sleeping bag and a woolen vest suddenly there was snow on Herman’s stubbly beard, and he came in with a big lump of white ice in the kettle.
Erik developed afresh with splendid results.
Even though the ghost words carried through the air by short wave were an unknown luxury in Kon-Tiki’s early days, the long ocean waves beneath us were the same as of old and they carried the balsa raft steadily westward as they did then, fifteen hundred years ago.
The weather became a little more unsettled, with scattered rain squalls, after we had entered the area nearer the South Sea islands and the trade wind had changed its direction. It had blown steadily and surely from the southeast until we were a good way over in the Equatorial Current; then it had veered round more and more toward due east. We reached our most northerly position on June 10 with latitude 6° 19′ south. We were then so close up to the Equator that it looked as if we should sail above even the most northerly islands of the Marquesas group and disappear completely in the sea without finding land. But then the trade wind swung round farther, from east to northeast, and drove us in a curve down toward the latitude of the world of islands.
It often happened that wind and sea remained unchanged for days on end, and then we clean forgot whose steering watch it was except at night, when the watch was alone on deck. For, if sea and wind were steady, the steering oar was lashed fast and the Kon-Tiki sail remained filled without our attending to it. Then the night watch could sit quietly in the cabin door and look at the stars. If the constellations changed their position in the sky, it was time for him to go out and see whether it was the steering oar or the wind that had shifted.
It was incredible how easy it was to steer by the stars when we had seen them marching across the vault of the sky for weeks on end. Indeed, there was not much else to look at at night. We knew where we could expect to see the different constellations night after night, and, when we came up toward the Equator, the Great Bear rose so clear of the horizon in the north that we were anxious lest we should catch a glimpse of the Pole Star, which appears when one comes from southward and crosses the Equator. But as the northeasterly trade wind set in, the Great Bear sank again.
The old Polynesians were great navigators. They took bearings by the sun by day and the stars by night. Their knowledge of the heavenly bodies was astonishing. They knew that the earth was round, and they had names for such abstruse conceptions as the Equator and the northern and southern tropics. In Hawaii they cut charts of the ocean on the shells of round bottle gourds, and on certain other islands they made detailed maps of plaited boughs to which shells were attached to mark the islands, while the twigs marked particular currents. The Polynesians knew five planets, which they called wandering stars, and distinguished them from the fixed stars, for which they had nearly two hundred different names. A good navigator in old Polynesia knew well in what part of the sky the different stars would rise and where they would be at different times of the night and at different times of the year. They knew which stars culminated over the different islands, and there were cases in which an island was named after a star which culminated over it night after night and year after year.
Apart from the fact that the starry sky lay like a glittering giant compass revolving from east to west, they understood that the different stars right over their heads always showed them how far north or south they were. When the Polynesians had explored and brought under their sway their present domain, which is the whole of the sea nearest to America, the
y maintained traffic between some of the islands for many generations to come. Historical traditions relate that, when the chiefs from Tahiti visited Hawaii, which lay more than 2,000 sea miles farther north and several degrees farther west, the helmsman steered first due north by sun and stars, till the stars right above their heads told them that they were on the latitude of Hawaii. Then they turned at a right angle and steered due west till they came so near that birds and clouds told them where the group of islands lay.
Whence had the Polynesians obtained their vast astronomical knowledge and their calendar, which was calculated with astonishing thoroughness? Certainly not from Melanesian or Malayan peoples to the westward. But the same old vanished civilized race, the “white and bearded men,” who had taught Aztecs, Mayas, and Incas their amazing culture in America, had evolved a curiously similar calendar and a similar astronomical knowledge which Europe in those times could not match. In Polynesia, as in Peru, the calendar year had been so arranged as to begin on the particular day of the year when the constellation of the Pleiades first appeared above the horizon, and in both areas this constellation was considered the patron of agriculture.
In Peru, where the continent slopes down toward the Pacific, there stand to this day in the desert sand the ruins of an astronomical observatory of great antiquity, a relic of the same mysterious civilized people which carved stone colossi, erected pyramids, cultivated sweet potatoes and bottle gourds, and began their year with the rising of the Pleiades. Kon-Tiki knew the movement of the stars when he set sail upon the Pacific Ocean.
On July 2 our night watch could no longer sit in peace studying the night sky. We had a strong wind and nasty sea after several days of light northeasterly breeze. Late in the night we had brilliant moonlight and a quite fresh sailing wind. We measured our speed by counting the seconds we took to pass a chip, flung out ahead on one side of us, and found that we were establishing a speed record. While our average speed was from twelve to eighteen “chips,” in the jargon current on board, we were now for a time down to “six chips,” and the phosphorescence swirled in a regular wake astern of the raft.
Four men lay snoring in the bamboo cabin while Torstein sat clicking with the Morse key and I was on steering watch. Just before midnight I caught sight of a quite unusual sea which came breaking astern of us right across the whole of my disturbed field of vision. Behind it I could see here and there the foaming crests of two more huge seas like the first, following hard on its heels. If we ourselves had not just passed the place, I should have been convinced that what I saw was high surf flung up over a dangerous shoal. I gave a warning shout, as the first sea came like a long wall sweeping after us in the moonlight, and wrenched the raft into position to take what was coming.
When the first sea reached us, the raft flung her stern up sideways and rose up over the wave back which had just broken, so that it hissed and boiled all along the crest. We rode through the welter of boiling foam which poured along both sides of the raft, while the heavy sea itself rolled by under us. The bow flung itself up last as the wave passed, and we slid, stern first, down into a broad trough of the waves. Immediately after the next wall of water came on and rose up, while we were again lifted hurriedly into the air and the clear water masses broke over us aft as we shot over the edge. As a result the raft was flung right broadside on to the seas, and it was impossible to wrench her round quickly enough.
The next sea came on and rose out of the stripes of foam like a glittering wall which began to fall along its upper edge just as it reached us. When it plunged down, I saw nothing else to do but hang on as tight as I could to a projecting bamboo pole of the cabin roof; there I held my breath while I felt that we were flung sky-high and everything round me carried away in roaring whirlpools of foam. In a second we and the Kon-Tiki were above water again and gliding quietly down a gentle wave back on the other side. Then the seas were normal again. The three great wave walls raced on before us, and astern in the moonlight a string of coconuts lay bobbing in the water.
The last wave had given the cabin a violent blow, so that Torstein was flung head over heels into the radio corner and the others woke, scared by the noise, while the water gushed up between the logs and in through the wall. On the port side of the foredeck the bamboo wickerwork was blown open like a small crater, and the diving basket had been knocked flat up in the bow, but everything else was as it had been. Where the three big seas came from, we have never been able to explain with certainty, unless they were due to disturbances on the sea bottom, which are not so uncommon in these regions.
Two days later we had our first storm. It started by the trade wind dying away completely, and the feathery, white trade-wind clouds, which were drifting over our heads up in the topmost blue, being suddenly invaded by a thick black cloud bank which rolled up over the horizon from southward. Then there came gusts of wind from the most unexpected directions, so that it was impossible for the steering watch to keep control. As quickly as we got our stern turned to the new direction of the wind, so that the sail bellied out stiff and safe, just as quickly the gusts came at us from another quarter, squeezed the proud bulge out of the sail, and made it swing round and thrash about to the peril of both crew and cargo. But then the wind suddenly set in to blow straight from the quarter whence the bad weather came, and, as the black clouds rolled over us, the breeze increased to a fresh wind which worked itself up into a real storm.
In the course of an incredibly short time the seas round about us were flung up to a height of fifteen feet, while single crests were hissing twenty and twenty-five feet above the trough of the sea, so that we had them on a level with our masthead when we ourselves were down in the trough. All hands had to scramble about on deck bent double, while the wind shook the bamboo wall and whistled and howled in all the rigging.
To protect the radio corner we stretched canvas over the rear wall and port side of the cabin. All loose cargo was lashed securely, and the sail was hauled down and made fast around the bamboo yard. When the sky clouded over, the sea grew dark and threatening, and in every direction it was white-crested with breaking waves. Long tracks of dead foam lay like stripes to windward down the backs of the long seas; and everywhere, where the wave ridges had broken and plunged down, green patches like wounds lay frothing for a long time in the blue-black sea. The crests blew away as they broke, and the spray stood like salt rain over the sea. When the tropical rain poured over us in horizontal squalls and whipped the surface of the sea, invisible all round us, the water that ran from our hair and beards tasted brackish, while we crawled about the deck naked and frozen, seeing that all the gear was in order to weather the storm.
When the storm rushed up over the horizon and gathered about us for the first time, strained anticipation and anxiety were discernible in our looks. But when it was upon us in earnest, and the Kon-Tiki took everything that came her way with ease and buoyancy, the storm became an exciting form of sport, and we all delighted in the fury round about us which the balsa raft mastered so adroitly, always seeing that she herself lay on the wave tops like a cork, while all the main weight of the raging water was always a few inches beneath. The sea had much in common with the mountains in such weather. It was like being out in the wilds in a storm, up on the highest mountain plateaus, naked and gray. Even though we were right in the heart of the tropics, when the raft glided up and down over the smoking waste of sea we always thought of racing downhill among snowdrifts and rock faces.
The steering watch had to keep its eyes open in such weather. When the steepest seas passed under the forward half of the raft, the logs aft rose right out of the water, but the next second they plunged down again to climb up over the next crest. Each time the seas came so close upon one another that the hindmost reached us while the first was still holding the bow in the air. Then the solid sheets of water thundered in over the steering watch in a terrifying welter, but next second the stern went up and the flood disappeared as through the prongs of a fork.
Herman was out all the time with his anemometer measuring the squalls of gale force, which lasted for twenty-four hours. Then they gradually dropped to a stiff breeze with scattered rain squalls, which continued to keep the seas boiling round us as we tumbled on westward with a good sailing wind. To obtain accurate wind measurements down among the towering seas Herman had, whenever possible, to make his way up to the swaying masthead, where it was all he could do to hold on.
When the weather moderated, it was as though the big fish around us had become completely infuriated. The water round the raft was full of sharks, tunnies, dolphins, and a few dazed bonitos, all wriggling about close under the timber of the raft and in the waves nearest to it. It was a ceaseless life-and-death struggle; the backs of big fishes arched themselves over the water and shot off like rockets, one chasing another in pairs, while the water round the raft was repeatedly tinged with thick blood. The combatants were mainly tunnies and dolphins, and the dolphins came in big shoals which moved much more quickly and alertly than usual. The tunnies were the assailants; often a fish of 150 to 200 pounds would leap high into the air holding a dolphin’s bloody head in its mouth. But, even if individual dolphins dashed off with tunnies hard on their heels, the actual shoal of dolphins did not give ground, although there were often several wriggling round with big gaping wounds in their necks. Now and again the sharks, too, seemed to become blind with rage, and we saw them catch and fight with big tunnies, which met in the shark a superior enemy.
