Potosi

Potosi was a five-masted steel barque built in 1895 by Joh. C. Tecklenborg ship yard in Geestemünde, Germany, for the sailing ship company F. Laeisz as a trading vessel. Its primary purpose was as a "nitrate clipper" collecting guano in South America for use in chemical companies in Germany (mainly for making explosives and fertiliser). As its shipping route was between Germany and Chile, it was designed to be capable of withstanding the rough weather encountered around Cape Horn. Potosi was named after the Bolivian town of Potosí (the highest city in the world), its name beginning with "P" according to a Laeisz' tradition begun in the 1880s. The Potosi and sister ships became known as the Flying P Line and were described by Robert Carter as "without doubt, the most successful fleet of sail-driven ships ever assembled under one flag..." Potosi had five masts and was rigged as a barque, meaning that the first four masts were square-rigged, each carrying six sails, and the fifth mast carried three fore-and-aft-sails. She was the third windjammer in the world merchant fleet with that kind of rigging, after the France I of the Antoine-Dominique Bordes line of Bordeaux, and the first German (auxiliary) steel barque Maria Rickmers of the Rickmers line. In total, within the world merchant fleet, there were only six windjammers of this class of five-masted barque rigging, with four masts having carried five, six or partly seven sails on each mast: France I, Maria Rickmers (carried seven sails (skysails) on fore, main, mizzen masts, jigger mast with six sails), Potosi, R.C. Rickmers, France II (carried five sails as a bald header), and København. The Potosi's shipping line sister ship, Preussen also had five masts, but was square rigged on each mast. The idea of building such a ship for the Laeisz fleet came from the famous Laeisz-captain Robert Hilgendorf, who was to become the Potosi's first master. His considerations and ideas had a great influence on the ship's design and he was the supervising ship officer when the huge barque was under construction. She was assigned the call sign RKGB, and as with all P-liners her hull was black with a white waterline and a red underwater ship—the colours of the German flag at that time. Author Daniel S.
