| (1) |
In addition to the principles in item 5 of this annex, the following factors shall be taken into account and properly acted upon by the officer in charge of the navigational watch: |
| (a) |
other vessels engaged in fishing and their gear, own vessel's manoeuvring characteristics, particularly its stopping distance and the diameter of turning circle at sailing speed and with the fishing gear overboard; |
| (b) |
safety of the crew on deck; |
| (c) |
adverse effects on the safety of the vessel and its crew through reduction of stability and freeboard caused by exceptional forces resulting from fishing operations, catch handling and stowage, and unusual sea and weather conditions; |
| (d) |
the proximity of offshore structures, with special regard to any safety zones; |
| (e) |
wrecks and other underwater obstacles that could be hazardous for fishing gear. |
| (2) |
When stowing the catch, attention shall be given to the essential requirements for adequate freeboard, adequate stability and watertight integrity at all times during the voyage to the landing port, taking into account consumption of fuel and stores, risk of adverse weather conditions and, especially in winter, risk of ice accretion on or above exposed decks in areas where ice accretion is likely to occur. |
The Master shall ensure, with a view to the safety of the vessel and the crew, that a proper watch is maintained at all times from the wheelhouse or deck on fishing vessels at anchor.

continue to be responsible for the safe navigation of the ship, despite the presence of the Master on the bridge, until informed specifically that the Master has assumed that responsibility and this is mutually understood; and |
| (2) |
During the watch, the course steered, position and speed shall be checked at sufficiently frequent intervals, using any available navigational aids necessary, to ensure that the ship follows the planned course. |
| (3) |
The officer in charge of the navigational watch shall have full knowledge of the location and operation of all safety and navigational equipment on board the ship and shall be aware and take account of the operating limitations of the equipment. |
| (4) |
The officer in charge of the navigational watch shall not be assigned or undertake any duties that would interfere with the safe navigation of the ship. |
| (5) |
When using radar, the officer in charge of the navigational watch shall bear in mind the necessity to comply at all times with the provisions on the use of radar contained in the collision regulations. |
| (6) |
In cases of need, the officer in charge of the navigational watch shall not hesitate to use the helm, engines and sound signalling apparatus.

The officer in charge of the navigational watch shall use the radar whenever restricted visibility is encountered or expected, and at all times in congested waters, having due regard to its limitations. |
| (16) |
The officer in charge of the navigational watch shall ensure that range scales employed are changed at sufficiently frequent intervals so that echoes are detected as early as possible. It shall be borne in mind that small or poor echoes may escape detection. |
| (17) |
Whenever radar is in use, the officer in charge of the navigational watch shall select an appropriate range scale and observe the display carefully, and shall ensure that plotting or systematic analysis begins in ample time. |
| (18) |
The officer in charge of the navigational watch shall notify the Master immediately: |
| (a) |
if restricted visibility is encountered or expected; |
| (b) |
if the traffic conditions or the movements of other ships are causing concern; |
| (c) |
if difficulty is experienced in maintaining course; |

if the radio equipment malfunctions; |
| (h) |
in heavy weather, if in any doubt about the possibility of weather damage; |
| (i) |
if the ship meets any hazard to navigation, such as ice or a derelict; and |
| (j) |
in any other emergency or if in any doubt. |
| (19) |
Despite the requirement to notify the Master immediately in the foregoing circumstances, the officer in charge of the navigational watch shall in addition not hesitate to take immediate action for the safety of the ship, where circumstances so require. |
| (20) |
The officer in charge of the navigational watch shall give watchkeeping personnel all appropriate instructions and information that will ensure the keeping of a safe watch, including a proper look- out. |
| 7 |
Watchkeeping under different conditions and in different areas |
| (a) |
The officer in charge of the navigational watch shall take frequent and accurate compass bearings of approaching ships as a means of early detection of risk of collision and bear in mind that such risk may sometimes exist even when an appreciable bearing change is evident, particularly when approaching a very large ship or a tow or when approaching a ship at close range. The officer shall also take early and positive action in compliance with the applicable collision regulations, and subsequently check that the action is having the desired effect. |
| (b) |
In clear weather, whenever possible, the officer in charge of the navigational watch shall carry out radar practice. |
If the Master considers it necessary, a continuous navigational watch shall be maintained at anchor. While at anchor, the officer in charge of the navigational watch shall:
| (a) |
determine and plot the ship's position on the appropriate chart as soon as practicable; |
| (b) |
when circumstances permit, check at sufficiently frequent intervals whether the ship is remaining securely at anchor by taking bearings of fixed navigation marks or readily identifiable shore objects; |
| (c) |
ensure that proper look-out is maintained; |
| (d) |
ensure that inspection rounds of the ship are made periodically; |
| (e) |
observe meteorological and tidal conditions and the state of the sea; |
| (f) |
notify the master and undertake all necessary measures if the ship drags anchor; |
| (g) |
ensure that the state of readiness of the main engines and other machinery is in accordance with the master's instructions; |
| (h) |
if visibility deteriorates, notify the Master; |
| (i) |
ensure that the ship exhibits the appropriate lights and shapes and that appropriate sound signals are made in accordance with all applicable regulations; |
| (j) |
take measures to protect the environment from pollution by the ship and comply with applicable pollution regulations. |
