Any boat owner or ship captain knows there are many navigation rules and keeping them straight can be a challenge. Used by the US Coast Guard, US Coast Guard Auxiliary and US Power Squadron, the Davis Instruments Navigation Rules card is a handy way to look up what you need quickly. This Navigation Rules Quick Reference Card includes the US Buoyage System, Inland and International Rules, Right-of-Way, Lights, Sound Signals, and Bridge Signals. The card also includes zones of approach, distress signals, how to recognize lights of different ships and passage signals at night, and what to do if you are in doubt of a rule under certain circumstances. The information on the card is presented in a way that is legible and concise. Colors and shading help separate the different sections of information, making it easy to find. The Navigation Rules Card is full color on both sides, and it is three-hole punched for a binder or bulkhead mounting. It’s also weatherproof and made from durable plastic, allowing it to withstand anything that comes your way. The Navigation Rules Quick Reference Card measures 8½ × 11 inches (22 × 28 cm).
