The Trawler Captain Who Sailed by a School Atlas

A Two-Hour Chase Off Georgetown

On the evening of 18 June 1936, the British steamer Arakaka spotted a small vessel a few miles outside Georgetown harbour and radioed word to shore¹. An unarmed police launch went out to investigate, and as it closed in, the crew of the unidentified boat turned hostile, denying she was the missing Girl Pat and threatening violence if officers tried to board¹. The launch pulled back, the police armed themselves and got authority to seize the boat, and when they returned the next morning they found their quarry trying to slip away. What followed was a two-hour pursuit that one paper, the Hull Daily Mail, dressed up as sport¹.

Just two days before, several newspapers had reported something grimmer: the wreck of a small boat and three bodies found at Atwood Cay in the Bahamas, with one headline asking whether a school atlas had steered the crew to their deaths¹. It was wrong. Early on the morning of 19 June, a police launch towed the real Girl Pat into Georgetown harbour, battered but afloat, with everyone aboard alive¹.

The boat the police were chasing had left Grimsby almost three months earlier under very different circumstances. The Girl Pat was a small trawler, built in 1935 and owned by the Marstrand Fishing Company, converted for seine-net fishing and fitted out for crews of six¹. Her skipper, George Black Orsborne, known to everyone as Dod, was an Aberdeen-raised seaman who had joined the Royal Navy as a boy of fourteen and spent the following decade doing, in his own words, "a bit of everything, rum-running, whaling, deep-sea trawling in the Arctic"¹. His younger brother James came along as an unauthorized passenger, and the owners expected the boat back within two or three weeks after an ordinary North Sea trip to the Dogger Bank^1,3.

It did not go that way. Days out from Grimsby, after dropping the regular engineer George Jefferson at Dover without telling him what was happening, Orsborne gathered the rest of the crew in the wheelhouse and told them this was no normal fishing trip¹. He then showed them something that would define the whole affair: there were no charts aboard, only a cheap school atlas he intended to steer by¹. He had the boat's registration number blacked out and her bowsprit altered, and false names went into the log¹.

From there the Girl Pat worked her way south through the Bay of Biscay, rested at Corcubión in Spain, and continued down the West African coast past the Savage Islands to Dakar before turning west across the Atlantic^1,6,7. Sources differ on the exact distance, somewhere between 5,000 and 6,000 nautical miles depending on how the route is measured, but agree on the method: an atlas, a compass, and whatever local knowledge the crew could pick up along the way^2,8. The vessel is believed to have taken on water at the Îles du Salut off French Guiana before making its final approach to British Guiana^1,9.

By the time the Girl Pat reached Georgetown, the story had already made Orsborne famous in Britain, with reports of sightings, a false distress call under the name "Margaret Harold," and even interest from Gaumont British in a feature film¹. What the chase and the capture exposed was not a shipwreck but a theft, and in the following months the real contest moved from the sea to a London courtroom. There, Orsborne's defense claimed the Marstrand Fishing Company had wanted the boat "done away with" so it could collect on a £3,000 insurance policy, and that his voyage was part of that scheme rather than a simple theft^4,3,5. The owners denied being under any financial pressure, the defense fell apart under cross-examination, and the jury convicted both brothers: eighteen months for George, twelve for James^1,4,5.

The Girl Pat herself outlived the scandal. A Georgetown syndicate sailed her home to Portsmouth in May 1937, after which she toured as a tourist attraction before being sold on for wreck-marking work and requisitioned during the war^1,3. Orsborne later claimed in his memoirs that the whole voyage had actually been a secret mission for British Naval Intelligence tied to the outbreak of the Spanish Civil War, a story no other source corroborates^1,3. He died of a heart attack in France in 1957, having gone on to further scrapes, including an arms-smuggling arrest in Trinidad during a later voyage retracing Charles Darwin's route on the Beagle². Whatever he was actually doing out there with his school atlas, the two-hour chase off Georgetown was the moment the rest of the world caught up with him.
