Determine course to steer

Function: Navigation at the operational level

Competence Knowledge, Understanding & Proficiency Task

Plan and conduct a passage and determine position

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

Determine course to steer

Assessed in: MT-2121 Deep Sea Navigation

Condition

On a ship underway, under laboratory conditions, or in a full mission ship simulator, with the ship‘s speed of at least 10 knots, and using a plotting sheet or chart, when encountering wind and current which sets the vessel. Given adequate radar ranges and visual or electronic bearings.

Behavior

Plot the vessel’s position on at least two successive occasions not less than 30 minutes apart, for a vessel steaming at 20 kts, and calculate set and drift by vector analysis and determine the course to steer to make the intended course.

Standard

The course to steer is within ± 5° of the assessor’s solution.
