Albatross, originally named Albatros, later Alk, was a sailing ship that became famous when she sank in 1961 with a group of American teenagers on board.

From fall 1960 to spring 1961, a crew of four instructors (including the Sheldons), a cook and 13 students sailed the Albatross from the Bahamas through the Caribbean to the Galápagos Islands and back to the Caribbean; a fourteenth student had been on the ship for the first part of the voyage, but had left in Balboa, Panama. At the beginning of May, the Albatross was en route from Progreso, Mexico, to Nassau, the Bahamas. On 1 May, skipper Sheldon decided that they would make a stop at one of the Florida Keys to refuel.
Shortly after 8:30 am on 2 May 1961 the Albatross was hit by a sudden squall about 125 miles (200 km) west of the Dry Tortugas. She heeled over suddenly and sank almost instantly, taking with her Alice Sheldon, the ship's cook George Ptacnik, and students Chris Coristine, John Goodlett, Rick Marsellus, and Robin Wetherill (John Goodlett was on deck in the last minutes, but probably became entangled in some of the lines or a sail of the sinking ship while freeing a lifeboat, and Christopher Coristine reportedly went below deck in an attempt to save someone else). As there had not been time to send out a radio distress signal before she was lost, the remaining crew used her two lifeboats to make way towards Florida. Around 7:30 a.m. on 3 May, the two boats were found by the Dutch freighter Gran Rio, which took the survivors to Tampa, Florida.
According to Sheldon, the squall hitting the Albatross was a white squall, i.e. an unpredictably sudden, very strong squall. His opinion was that the Albatross was essentially a stable, "safe" ship, and that the crew of teenagers—who had already spent about eight months on board—were sufficiently trained, but that this rare weather phenomenon left the ship no chance. Critics of this view, however, have argued that refittings of the Albatross over the years by her various owners had made her top heavy, which affected her secondary stability, that is, her ability to remain stable or even right herself after tilting to the side, as opposed to capsizing. In her times as North Sea pilot schooner, the ship had a far smaller and lower sail area, which means that the force of the wind did not have as much power and as powerful an angle as it did the day she sank. Almost 40 years after the loss of the Albatross, Daniel S. Parrott reanalyzed some of the documents about the ship and comparable ships in his book, Tall Ships Down. He suggested that due to the ship's impaired stability, even a "normal" squall could have sunk her; according to him, only the expert handling of the ship and the habitual prudence of the ship's captain(s) to reduce sail area early had prevented the refitted Albatross from capsizing in previous strong wind conditions.
