Watch arrangements When deciding the composition of the watch on the bridge, which may include appropriately qualified ratings, the following factors, inter alia, shall be taken into account- (a) at no time shall the bridge be left unattended; (b) weather conditions, visibility and whether there is daylight or darkness; (c) the proximity of navigational hazards which may make it necessary for the officer in charge of the watch to carry out additional navigational duties; (d) the use and operational condition of navigational aids such as radar or electronic position-indicating devices and any other equipment affecting the safe navigation of the ship; (e) whether the ship is fitted with automatic steering; (f) whether there are radio duties to be performed; (g) unmanned machinery space controls, alarms and indicators provided on the bridge, procedures for their use and limitations; and (h) any unusual demands on the navigational watch that may arise as a result of special operational circumstances. 4. Taking over the watch (1) The officer in charge of the navigational watch shall not hand over the watch to the relieving officer if there is reason to believe that the latter is not capable of carrying out the watchkeeping duties effectively, in which case the master shall be notified. (2) The relieving officer shall ensure that the members of the relieving watch are fully capable of performing their duties, particularly as regards their adjustment to night vision. Relieving officers shall not take over the watch until their vision is fully adjusted to the light conditions. (3) Prior to taking over the watch, relieving officers shall satisfy themselves as to the ship's estimated or true position and confirm its intended track, course and speed, and unmanned machinery space controls as appropriate and shall note any dangers to navigation expected to be encountered during their watch. (4) Relieving officers shall personally satisfy themselves regarding the following- (a) standing orders and other special instructions of the master relating to the navigation of the ship; (b) position, course, speed and draught of the ship; (c) prevailing and predicted tides, currents, weather, visibility and the effect of these factors upon course and speed; (d) procedures for the use of main engines to manoeuvre when the main engines are on bridge control; (e) navigational situation, including but not limited to- (i) the operational condition of all navigational and safety equipment being used or likely to be used during the watch; (ii) the errors of the gyro and magnetic compasses; |
