On August 6, 1848, Captain Peter M’Quhae and officers of the HMS Daedalus saw a 60-foot serpentine animal in the South Atlantic between the Cape of Good Hope and the island of Saint Helena, on passage from the East Indies to England, about 300 miles off the coast of Namibia.
At about 5:00 P.M. M’Quhae, Lieutenant Edgar Drummond, and William Barrett, sailing master, were pacing the quarterdeck when suddenly a seaman reported a strange object off the starboard beam.
Apparently, the creature kept its head and short neck about 4 feet above the surface of the water. The animal moved at a steady speed in the water and was about 600 feet away at the closest point.
The color was dark brown, with yellowish-white on the throat. A horselike mane or dorsal fin was visible on its back. They watched it for five minutes with the naked eye and fifteen more minutes through a spyglass. What they saw prompted the captain to exclaim, “This must be that animal called the sea-serpent.”
When Daedalus reached London, immediately Captain M’Quhae submitted a report about the description of the creature to Admiral Sir W. H. Gageto and to The Times. He also supervised a detailed drawing of the 60 feet-long creature that was visible for 20 minutes, as follows:
“It was discovered to be an enormous serpent, with head and shoulders kept about four feet constantly above the surface of the sea, and as nearly as we could approximate by comparing it with what our maintopsail-yard would show in the water, there was at least sixty foot of the animal a fleur d’eau [showing above the surface], no portion of which was, to our perception, used in propelling it through the water, either by vertical or horizontal undulation.
“It passed rapidly, but so close under our lee quarter that, had it been a man of my acquaintance, I should have easily recognized his features with the naked eye; and it did not, either in approaching the ship or after it had passed our wake, deviate in the slightest degree from its course to the southwest, which it held on at the pace of from twelve to fifteen miles per hour, apparently on some determined course.
“The diameter of the serpent was about fifteen or sixteen inches behind the head, which was, without any doubt, that of a snake; and it was never, during the twenty minutes that it continued in sight of our glasses, once below the surface of the water; its color, a dark brown, with yellowish white about the throat. It had no fins, but something like the mane of a horse, or rather a bunch of sea-weed, washed about its neck.”
The objectivity characteristic of ships’ officers who are accustomed to describing and analyzing dispassionately what they see is obvious.
However, his story was rejected by palaeontologist Professor Richard Owen, who insisted the crew had seen a giant seal. Sceptics immediately suggested floating seaweed or a giant python or crocodile that had lost its bearings as explanations for the Daedalus sighting.
But could the captain and all crew be wrong about what they saw? Skepticism is the easiest way: believe nothing, do nothing. People rarely visit great depths. So it’s very important to analyze what they encounter there.
