This report contains the results of the performance and maneuvering trials conducted on USNS HAYES (T-AGOR 16). Trials were conducted with and without a towed array. Standardization trials were conducted at design, under-design, and over-design propeller pitch settings throughout a speed range of approximately 4 to 15 knots. For the design and off-design propeller pitches the shaft power remained essentially constant at any given speed. At 10 knots HAYES is laterally stable and requires 0.5 degree right rudder to maintain a straight course. Right and left rudder are equally effective in initiating and checking changes in course. When towing the array, the following restraints were observed. It was necessary to tow the array at such a speed that the array maintained a consant depth. The highest towing speed tested which did not exceed the array towing cable limits was approximately 12.7 knots. When making course changes greater than 360 degrees with the array deployed, no rudder angle greater than 5 degrees was used. This was done to avoid fouling of the array with the hulls or propellers. Within the limits of the above restraints, the towed array had no significant effect on HAYES' powering and maneuvering characteristics. (Author)
