Steady Reduce swing as rapidly as possible. Steady as she goes Steer a steady course on the compass heading indicated at the time of the order. The helmsman is to repeat the order and call out the compass heading on receiving the order. When the ship is steady on that heading, the helmsman is to call out: 'Steady on . . .' Keep the buoy / mark / beacon on port / starboard side.   Report if she does not answer the wheel.   Finished with the wheel.
	When the Officer of the watch requires a course to be steered by compass, the direction in which he wants the wheel turned should be stated followed by each numeral being said separately, including zero, for example:
	ORDER COURSE TO BE STEERED 'Port, steer one eight two' 182° 'Starboard, steer zero eight two' 082° 'Port, steer three zero five' 305°
	On receipt of an order to steer, for example, 182°, the helmsman should repeat it and bring the ship round steadily to the course ordered. When the ship is steady on the course ordered, the helmsman is to call out: 'Steady on one eight two'. The person giving the order should acknowledge the helmsman's call out. If it is desired to steer on a selected mark the helmsman should be ordered to: 'Steer on . . . buoy . . . (mark) . . . (beacon)'. The helmsman should repeat the order and when steady on the mark call out: 'Steady on . . . buoy . . . (mark) . . . (beacon)'. The person giving the order should acknowledge the helmsman's call out. * Note: When there is concern that the helmsman is inattentive he should be questioned and he should respond in accordance with the terminology in section 'Course': this is a reminder to the helmsman to mind his helm.
