Quick Reference Cards

Davis Instruments has introduced a new range of Quick Reference Cards, designed to deliver essential information in a clear, colourful format, ideal for boat owners or charter sailors looking for a quick answer.

The 22cm x 28cm weatherproof, high-strength plastic pages are expertly illustrated and organised. Three-hole punched, the set of seven cards can be kept conveniently at hand in a binder.

Covering boating in general, the basic Boating Guide includes a pre-departure checklist and emergency procedures. Dead reckoning, true-magnetic and compass relationships are a few of the subjects of the Coastwise Piloting QRC. A time-distance-speed calculator and bearing gauge are included. Navigation rules, International Maritime Buoyage System and COLREGS, celestial navigation, marine electronics and weather forecasting are just some of the additional topics covered.
