Results are reported for a series of experiments in which forces associated with a propeller fitted with a partial shroud are measured. The shroud is partial in the sense that it subtends only 180 of the propeller circumference rather than the full circumference, as is commonly the case. S. J. Gordon in 1966 proposed that such a shroud could be used as a rudder if mounted so that it can be moved from one side to another on the propeller circumference.
