The average speed observed was 12.86 knots and _ the speed from revolutions and propeller pitch was 12.20 knots. The negative slip would indicate that the revolu- tions as observed were somewhat in error. Brake horsepower of the en- gine averaged 3090 and the indicated horsepower averaged 4152 during the speed trial. Both of these figures were taken from the power and revo- lutions curve developed during shop - — PORT SIDE ENGINE ROOM M. S.

Average fuel per brake horsepower per hour was 0.42-pound and per indicated horse power per hour 0.312-pound based on the power developed by the main en- gine. It is anticipated that a speed in service fully loaded of 12.25 knots can be maintained.
