Charts feature fine contours and easy-to-distinguish color gradations of the depth line, turquoise for coral reefs, red for the 2 meter line, and blue for the 5 meter areas. They're a manageable size for both small and large boats 23-1/2 by 16-1/2inch sheets packaged in a thick plastic envelope. A magnifier and key to symbols are included. Also feature good land topography with well-marked rivers, towns, and street plans to assist with eyeball navigation. They also give a clear overall view of the shoreside facilities that are available. Waypoints are highlighted in red; all charts are adjusted to WGS 84 datum. Heights and depths are in meters. All area charts are scaled consistently (1:90,000; passage charts are at 1:500,000). Large-scale approaches and land contour markings simplify harbor approaches. Charts are coordinated with Chris Doyle's well-known cruising guides for the Virgin, Leeward, and Windward Islands.
