Navigation Equipment (continued)
Fishermen are cautioned when using courses between waypoints with Loran C, the course and distance may be displayed as a Great Circle route and not a straight rhumbline. Fishermen should take this into account when laying their course. For more information see Radio Aids to Marine Navigation
Fixing arrangements for radar reflectors should be provided so that they can be fitted either on a rigid mount or suspended in the rigging. For maximum performance, reflector should be mounted according to the orientation marked on the reflector.
Make sure radar is operating before leaving port, and keep a radar watch when visibility is poor.
Radar reflectors are required for vessels less than 20 metres long, and for all non-metal vessels. Locate reflectors above all superstructure – at least 4 metres above the water if possible.
