Extract

This paper reviews the research carried out at the University of Hamburg on the predicted performance of the Dyna Ship, a project for an advanced sailing merchantman. The proposed rig incorporates a series of unstayed hollow rotatable masts with terylene sails set along aerodynamically curved yards. The masts and sails are handled hydraulically by remote control from the wheelhouse.

Sailing ship research at the Institut für Schiffbau (IfS) of Hamburg University probably began with a paper presented by Thieme to the Schiffbautechnische Gesellschaft (S.T.G.) in 1955 on the mechanics of sail propulsion. When during 1961–6 the Hamburg Research Council promoted a broad research programme on wind forces on ships, covering all current modern ship types, the opportunity was taken to include also the problems of wind propulsion. This part of the investigation was especially stimulated by an inquiry by Wilhelm Prolss, who proposed a new height-restricted wind propulsion system for large ships in line with modern technology and aerodynamics, now known as the Dyna Ship.
