SEN (L) is an operator's course, providing students with knowledge of the application of the Collision Regulations and principles to be observed in keeping a navigational watch while using electronic aids to plot the ship's position and progress. It also provides students with the appropriate action to take to avoid collisions in simulated exercises with the use of type-approved marine simulators.
