Full Color Nautical Charts and Aerial Photos! Used by generations of boaters, ChartKits are full-color reproductions of U.S. government and private charts spiral bound into popular cruising regions. Individual 22"x17" charts are spiral bound into easy-to-use regional compilations. Full size chart kits cover a complete region. Features include GPS datums, Latitude/Longitude, Loran grids, distances in nautical miles, and aerial photos of harbors and anchorages in popular destinations. The convenient-sized books are large enough to allow for manual plotting, yet small enough to sit on your nav-station or lap.
