312 RUDDER TRIALS, U. S. S. STERETT. 



on turning, at 28 knots and 35° helm, in quiet water. This seems to be a 

 disadvantage of a location of the steering engine forward in a ship of such 

 length. 



7. The greatest moment measured during these trials was obtained in 

 backing full power with full helm. The rudder moment for this condition 

 amounted to 1.6 times the moment recorded on steady turning at 28 knots 

 and 35° helm. 



With the results of these rudder trials at hand, it would be of interest 

 to determine, with precision, the path of the Sterett in turning with a view 

 to establishing the relation between the rudder moment and the maneuvering 

 qualities of this type of ship. 



To afford data for the design of steering gear and rudder posts, using 

 a definite factor of safety, such rudder trials as are here described should 

 be conducted in rough weather.
