The word schooner likely comes from an old Scots term for skipping stones across water. A schooner has two or more masts, all fore and aft rigged, with the foremast no taller than the mainmast. Instead of pushing like a square sail parachute, its sails work like a sideways wing while the keel resists sliding, so the ship can sail much closer to the wind and zigzag against it. Gaff rigs, staysail r...

In 2019 archaeologists clearing a burial ground under London's Euston station for a high speed rail line found a coffin whose lead plate named Matthew Flinders, lost for over 150 years. Born in 1774 in Lincolnshire, a surgeon's son, he joined the navy at 15 after reading Robinson Crusoe and sailed with William Bligh on his second breadfruit voyage through the Torres Strait. At the Glorious First o...

Guglielmo Marconi was born in Bologna in 1874 to a wealthy Italian landowner and Annie Jameson, granddaughter of the founder of Jameson whiskey. Tutored at home and never at university, he set up a lab in 1894 in a family attic once used for silkworms, pairing a spark oscillator with Édouard Branly's coherer, a tube of metal dust that conducts when radio waves hit it. In December 1894 he rang a be...

Marshallese stick charts are open frameworks of coconut frond midribs tied with coconut fiber, with cowrie shells or knotted junctions marking islands. They do not map land. The sticks show ocean swells and how islands bend and cross them, creating choppy intersections that act as an island's invisible shadow miles out to sea. Each chart was personal, readable only by the navigator who made it, an...

Lightships were vessels built never to sail, anchored as floating lighthouses over sandbanks and shoals where no tower could stand. The first modern one was placed in 1734 by Robert Hamblin off the Nore sandbank at the mouth of the Thames, run as a private venture with partner David Avery that charged passing merchants for the light. They added stations off Norfolk in 1736, the Owers in 1788, and...

In 1854 Hosea Lewis became keeper of a lighthouse in Newport, Rhode Island, and in 1857 moved his family onto Lime Rock, a sliver of stone in the harbor. Within four months he suffered a paralyzing stroke, and his 15 year old daughter Ida took over the work: hauling fuel, filling the lamps at sundown and midnight, trimming wicks, and polishing soot from the reflectors. She also rowed her siblings...

One four letter word, Fram, now names a crater on Mars, hardware on the International Space Station, a Romanian children's book, and a string of Norwegian sports clubs. It starts with the Norwegian Arctic exploration ship Fram, whose rounded hull let expanding pack ice squeeze it upward onto the ice instead of crushing it. The original vessel sits in the Fram Museum in Oslo, and the Hurtigruten Gr...

Before containers, cargo moved as break bulk: sacks of coffee, crates of machinery, and barrels of liquid carried aboard piece by piece by longshoremen, wedged in with dunnage and dug out again at every port. Ships often spent more time at the dock than at sea, and theft was rampant. Early box ideas stayed local: James Brindley's starvationer boats on the Bridgewater Canal carried ten coal contain...

For centuries sailors could find latitude from the noon sun or Polaris, but longitude required knowing the exact time at a reference point like London while at sea, and an error of just four seconds could put a ship more than a mile off course. Galileo proposed timing the eclipses of Jupiter's moons, which proved impossible from a rolling deck. In 1714 Britain's Longitude Act offered £20,000 for a...

The tavern legend of the king's shilling hidden in a tankard is a myth: press officers faced fines for trickery, and volunteers got a cooling off period. The real system was impressment. Between 1793 and 1812 the Royal Navy grew from about 135 ships and 36,000 men to 584 ships and 114,000 men. Conditions deterred volunteers: planners expected up to half a crew to die on major voyages, mostly from...

The hammock began as survival gear in two places at once. Spanish colonists took the word hamaca from the Taino and Arawak peoples of the Caribbean, and Columbus noted netted sleeping hammocks used for sleep and barter, first woven from tree bark and later from sisal. Raised above the forest floor, sleepers avoided snakes, ants, and damp rot. The episode rejects myths crediting Saxons or the Athen...

The Golden Hind was only 102 feet long and 20 feet wide, carrying 80 to 85 men and 22 guns at no more than about eight knots. Launched as the Pelican, a galleon modeled on the Nao Victoria, it left England in December 1577 with four other ships and 164 men on an expedition officially meant to find places meet to have traffic. In fact Queen Elizabeth I secretly backed Sir Francis Drake as a private...

The word galleon traces back to the Byzantine Greek galea, a kind of shark, and the ship earned the comparison. In the 1550s Spanish commanders such as Pedro Menendez de Aviles and Alvaro de Bazan reworked the bulky carrack, whose towering forecastle acted like a sail that could never be lowered. They cut the forecastle down, lengthened and narrowed the hull, and added a beakhead. Galleons were ca...

The Dutch Golden Age was built less on warships than on a pear shaped, lightly armed cargo ship called the fluyt, developed by shipwrights in Hoorn in the 16th century. Other European merchant ships were built to double as warships, with thick hulls, reinforced gun decks, and crews large enough to fight. The fluyt dropped most of the guns to maximize cargo. Its hull was narrow at the deck and bulg...

Poseidon's earliest worshippers would not have asked him to protect their ships. In the Mycenaean period, roughly 1600 to 1100 BC, Linear B administrative tablets from centers like Pylos and Thebes show him outranking Zeus, receiving major offerings under the title wanax, a supreme overlord. He was an inland, chthonic god of earthquakes, underground water, and horses. Linguists split on his name:...

On January 10, 1992, a storm near the International Date Line swept 12 containers off the Ever Laurel, bound from Hong Kong to Tacoma, Washington. One held 28,800 Friendly Floatees made in China for The First Years Inc.: yellow ducks, red beavers, blue turtles, and green frogs. Their cardboard packaging dissolved within hours, and because the toys had no drain holes they could not sink. Seattle oc...

Sailors once drank eight pints of beer a day because water spoiled in wooden casks. After England took Jamaica in 1655, rum gradually replaced beer, and each man got half a pint of 95.5 proof navy spirit daily, with predictable drunkenness, illness, and discipline problems. In 1740 Vice Admiral Edward Vernon ordered the rum mixed four parts water to one and served in two halves, before noon and af...

Telling a coworker the boss keelhauled you sounds harmless until you know what the Dutch word kielhalen, to drag along the keel, meant at sea. A heavy rope was looped under a ship's hull, the victim was tied to one end and thrown overboard, and his own crewmates hauled him beneath the barnacle crusted bottom to the other side. Some accounts describe dragging from bow to stern. The crew's pace deci...

The classic anchor shape on a sailor's tattoo caused almost as many problems as it solved. This episode explains how anchors really work, starting with the myth that weight alone holds a ship. Bronze Age stone anchors, Maori stones for waka, and Greek baskets of stones or lead filled logs relied on mass and friction, but water's buoyancy makes a rock lighter and a storm's pull too strong for any l...

Before dry docks, crews careened ships by grounding them at high tide and waiting for the water to drop, as the English warship Grace Dieu was bedded in the mud of the River Hamble in 1434 behind a brushwood and clay wall. This episode follows the long effort to empty water from around a hull instead. The Phoenicians built covered slipways at Kition in Cyprus around the 5th century BC, and Carthag...

In the early 1920s, Frederick Stanley Mockford, the officer in charge of radio at Croydon Airport in England, was asked to invent a spoken distress word that English and French crews on the Croydon to Le Bourget route could both understand. He chose mayday, a phonetic version of the French m'aider, from venez m'aider, come help me. Grammatically it is an infinitive, closer to shouting helping me t...

Christopher Columbus was born in Genoa around 1451, the son of a wool weaver who also ran a cheese stand, and he taught himself Latin, Portuguese, and Castilian. After surviving a shipwreck off Portugal in 1476 he reached Lisbon, the center of maritime exploration, married into a Portuguese noble family with access to his late father in law's charts, and worked in a cartography shop with his broth...

On May 6, 2023, hours before his coronation, King Charles III sent a joking message to former shipmates of HMS Bronington, the vessel he once commanded: splice the main brace. This episode traces how that order began as one of the most dangerous jobs on a square rigged warship. The main brace, the longest line in the running rigging, controlled the angle of the yards, and enemy gunners aimed high...

Robert Ballard was born in 1942 in landlocked Wichita, Kansas, grew up in Southern California where his father became chief engineer for the Minuteman missile program at North American Aviation, and was hooked on the ocean by the 1954 film of 20,000 Leagues Under the Sea. After degrees in chemistry and geology at UC Santa Barbara and geophysics in Hawaii, he moved from the Army to the U.S. Navy in...

In 1994 the Soviet Union handed its official whaling records to the international community, reporting 2,710 humpback whales killed over several decades. Secret state shadow ledgers told the truth: more than 48,000. This episode traces how whaling grew from subsistence hunts dating to at least 3000 BC, with 5,000 year old baleen whale harpoons found in coastal Brazil and Korean petroglyphs that ma...
