Quick Reference cards provide accurate, concise boating information when and where you need it most.
* They are great for all types of boaters from weekend day sailors to offshore cruisers and professional mariners.
* Printed in full color on weatherproof high strength plastic, 8.5" x 11" three-hole cards are impervious to conditions at sea which quickly destroy laminated paper references.
* Quick Reference Weather Forecasting shows how to use wind direction, barometric pressure and cloud type to predict the weather. Photos of cloud types and descriptions are included along with full listing of radio weather stations for official broadcasts, key information on fog, hazardous wave and surf conditions, storm warnings, hurricane avoidance and more.
