The ROADrule IALA from Weems and Plath is a simple to use navigation tool that helps translate your actual view of maritime buoys and navigation aids into the corresponding chart symbols and their meanings.
ROADrule works much the same way a slide rule does, by taking a large amount of complex information and making it quick to reference and understand. Great for making quick and confident decisions at the helm when unfamiliar buoys, lighthouses, or other navigation aids are present.
- 20 light characteristics
- Maneuvering and warning signals
- Displays 12 rules of the road
- Magnifying lens to easily read definitions
Makes an excellent aide for navigation classes and Coast Guard exams as well. It's constructed of durable plastic and stored in a vinyl sleeve.
