Officer of the Watch (Yachts) - Navigation and Radar

The first part of the Officer of the Watch (Yachts) – Navigation and Radar course includes lectures covering navigational theory, electronic navigation aids and chart work. Instruction is given in practical chart work, tidal calculation and radar plotting, combined with a series of exercises to practice these techniques.

Electronic navigation aids include GPS, eLoran, ECDIS, echo sounders and speed logs. There is a significant emphasis on radar and ARPA and interpreting the radar picture.

In week three, with the assistance of instructors, students develop and practice navigation techniques in our renowned multi-purpose radar and navigation bridge simulators. This is an assessed week where collision avoidance skills are developed and application of the Collision Regulations must be demonstrated.
