The Swells

In the Marshall Islands, the training began with a blindfold. A young apprentice lay in a canoe while his teacher towed him through shallow water around a reef. The instructor named what the apprentice’s body was learning. That is rilib — the backbone swell, generated by the northeast trade winds, present in every season. Here is kaelib — weaker, year-round, detectable only by someone who had been taught to feel it. The knowledge was not entering the mind. It was entering the inner ear.

The reef modeled a destination atoll. The near-shore wave patterns modeled ocean swells. When the blindfold came off, the apprentice’s eyes were the last sense to arrive at knowledge the body already held.

During actual voyages, the navigator lay prone in the canoe and read the ocean through the pitch and roll of the hull against his body. Stick charts — mattang for instruction, meddo for regional waters, rebbelib for the full island chain, made from coconut frond midribs and cowrie shells — were studied before departure and never consulted at sea. Each chart varied so much in form and interpretation that only the navigator who made it could fully read it. An outsider looking at the arrangement of sticks and shells could not see the swell patterns, because seeing was the wrong sense.

In 1976, Mau Piailug — born in 1932 on the island of Satawal in the Caroline Islands, trained since childhood — navigated the double-hulled canoe Hokule’a from Hawaii toward Tahiti. No instruments. No charts aboard. Twenty-five hundred miles of open Pacific. In Piailug’s working framework, he was not moving toward Tahiti. Tahiti was moving toward him. Not metaphor — operational reference frame. The navigator holds still; the destination advances across a grid of reference stars until it arrives. On the thirty-first day at sea, Piailug said they would see land soon. The next day, they did.

Korent Joel was from Rongelap Atoll. He learned wave piloting as a boy — reading the ocean through his body, the way navigators in the Marshall Islands had learned for centuries before him. In 1954, the United States detonated a thermonuclear weapon at Bikini Atoll. The fallout reached Rongelap. Joel’s training was interrupted. His family was displaced.

He became a cargo ship captain for the Marshall Islands government. In 2003, the last recognized ri-meto — master wave navigator — died. Joel was fifty-five. Custodianship of the tradition passed to him not by ceremony but by survival: he was the one who remained.

He had not completed his voyaging test before the nuclear fallout took Rongelap from him. In 2006, more than fifty years after his training began on an atoll he could no longer live on, Joel sailed from Kwajalein to Ujae and earned the title of ri-meto.

“The swells never change,” he said.

He trained his younger cousin Alson Kelen. He worked with anthropologist Joseph Genz to document what he knew. He wanted to write a textbook. He died in January 2017, at sixty-eight. The textbook was not finished.

In 1896, Captain Winkler of the Imperial German Navy collected several stick charts while stationed in the Marshall Islands. He published his findings in the Smithsonian Institution’s annual report. The National Museum of Natural History holds fifteen of these charts today. The navigators who made them are unnamed in the records.

Each chart is an address to a memory that died with the person who made it. The museum holds the key to a lock that no longer exists.
