Maintain a safe navigational watch

OICNW-A2.1 Watchkeeping

Thorough knowledge of the content, application and intent of the International Regulations for Preventing Collisions at Sea, 1972

On a vessel underway or on a simulator, using a magnetic compass, gyro-compass repeater (if fitted), azimuth circle, bearing circle or alidade, or other means resulting in equivalent accuracy,

the candidate determines if risk of collision exists with approaching meeting, crossing, and overtaking vessels.

The candidate:

1. Takes two visual bearings of an approaching vessel using an azimuth circle, bearing circle, alidade, or other means resulting in equivalent accuracy, to determine if the bearing to the approaching vessel is appreciably changing, and each observation is within ± 2.0° of the assessor’s solution; and

2. Takes two electronic bearings of an approaching vessel using radar or ARPA, to determine if the bearing to the approaching vessel is appreciably changing, and each observation is within ± 2.0° of the assessor’s solution.
