OICNW-A1.02 Terrestrial and coastal navigation

Ability to determine the ship’s position by use of:

.1 Landmarks

.2 Aids to navigation, including lighthouses, beacons and buoys .

3 Dead reckoning, taking into account winds, tides, currents and estimated speed
Condition Behavior Standard

On a vessel underway, or on a simulator, with land and aids to navigation in sight, using a standard bearing circle, alidade, or other device for taking bearings, and given a chart with a scale of no more than 1:150,000,

the candidate determines the bearings of at least two charted objects and plots them.

The candidate’s:

  1. Position is within ± 0.10 nm of the assessor’s solution;

  2. Crossing angles of bearing is not less than 30° nor more than 160° between bearings;

  3. Bearings of objects abeam or close to the beam are observed first; and

  4. The chart in use is the largest scale suitable for the waters being transited.
