LIGHTrule From OceanFare
Weems and Plath LightRule(Item #:7392)


If you have ever been on the water at night and wondered if the marine navigation lights you see are from an approaching or fleeing vessel, or if you wonder if the vessel is a fishing trawler or super tanker, then LIGHTrule is for you. This simple-to-use vessel identification tool is inexpensive and great for night travel.

LIGHTrule is also an excellent aide for navigation classes and Coast Guard exams. It identifies all USCG Colregs, and shows the actual view of vessels for port, starboard, bow and stern lights. It identifies 60 marine navigation light configurations, displays 15 day shapes, provides a magnifying lens to make vessel descriptions easy to read, and displays horn signals for restricted visibility.
