LightRule Collision Regulations Slide Rule

Is that ship a fishing boat or supertanker bearing down on you?

If you've been at sea at night and wondered if lights were from an approaching or fleeing vessel, the LightRule Collision Regulations Slide Rule is for you.

The LightRule is a simple but clever slide rule that identifies lighting configurations through coloured windows. LightRule is fully waterproof and very tough and will stand rough handling. LightRule is an important addition to your navigation tool kit.

The LightRule vessel identification tool incorporates the Lighting Regulations and has the following features:

• Shows the actual view of vessels' Port, Starboard, Bow and Stern lights
• Lists 60 possible light configurations
• Has in-built magnifying lens for easy reading
• Displays audible signals for restricted visibility, manoeuvering and warning
• Measures 16 x 5.25 inches

LightRule is an inexpensive security item for night travel and should be an essential part of any boat's equipment. LightRule is also an excellent aide for students of Lighting Regulations and Yachtmaster and Coast Guard exams.

The LightRule is great value, constructed of extremely durable plastic and stored in a vinyl sleeve.
