Providing all the necessary information for clear sailing from the Canadian border down the coast to the Panama Canal, including the Sea of Cortez, Yachtsman’s Chart Books are easy to use, inexpensive (about the cost of two charts) and designed to fit your needs. All charts are reproductions of official charts by the Defense Mapping Agency Hydrographic/Topographic Center. All pages are arranged with grid lines running parallel to the edge of the page. Every page has a compass rose and a scale. Important supplemental information such as chart symbols, wind scale, bridge openings, rules of the road, safety tips, sound signals, VHF radio channels, storm advisories and phonetic alphabet are included.
