The rigging

The Swedish Ship Götheborg is a three-masted ship with square sails on all three masts. The mainmast and the foremast have topgallant sails, topsails and courses. The aftermast has a topsail and a Latin type spanker sail. In the bow is the bowsprit with a jib boom, and hanging below that are two more square sails: the spritsail and the sprit-topsail. A ship of this kind used to be called a frigate rigged ship, although we now refer to it as a full-rigged ship.

The 18th century East Indiamen were mainly designed to sail in a tailwind. The rigging is an exact reconstruction of the original rigging from the 18th century. Built mainly using 18th century technology and materials. Planning work for the rigging began in late 1998/early 1999. By building an exact model of the hull and rigging in scale 1:20, it was possible to study all moving and fixed rigging, as well as how the ropes and sails worked. With the aid of Chalmers University of Technology and the Swedish National Shipbuilding and Ship Research Institute’s test facility, it was then possible to calculate loads and stresses in the rigging.
