MT-1221
Coastal Navigation
Course Description
This course introduces a student to the knowledge and practices necessary to carry out the routine day to day navigational watchkeeping duties in a proper and safe manner. The student will be able to understand and read information from a chart, fix the ship’s position in coastal waters, understand Earth’s magnetism, buoyage systems, check and compare magnetic and gyro compasses, obtaining and applying compass error. In addition, the student will be introduced to the basic concepts and obtain an understanding of electronic navigational aids Loran, Global Positioning System and Radar. Classwork is supplemented by practical chart plot exercises in the labs. [Lab time required]
Learning Objectives
Demonstrate knowledge and understanding of the following STCW elements:
- OICNW-A1.02 Ability to determine the ship’s position by use of landmarks
- OICNW-A1.02 Ability to determine the ship’s position by use of aids to navigation, including lighthouses, beacons and buoys
- OICNW-A1.02 Ability to determine the ship’s position by use of dead reckoning, taking into account winds, tides, currents and estimated speed
- OICNW-A1.06 Knowledge of the principles of magnetic and gyro-compasses
Other Objectives
At the completion of this course, cadets will have demonstrated via testing and practical assessment, the ability to safely navigate in coastal waters through:
- Reading and understanding nautical charts and publications
- Fast and Accurate plotting of Latitude and Longitude
- Fast and Accurate determination of and plotting of courses; true and magnetic
