WEEMS PLATH – LIGHT RULE
Identifies marine navigation lights: an approaching or fleeing vessel, a fishing trawler or super tanker. This simple-to-use vessel identification tool is an inexpensive security for night nav and should be an essential part of the equipment for navigation classes. To be used before leaving, not at sea!
Test your knowledge with this light and sound signals at sea rule (warning, manoeuvering and restricted visibility signals). Stern and starboard on one side and bow and port if turned upside down.
