Waterproof map with ebb & flood arrows, put-ins, campsites, bearings, distances, depths, etc. Part of a series of charts that are great for cruising the San Juan Islands and surrounding areas, the Strait of Juan de Fuca and 7 new maps for California. These maps have been developed in a scale and format ideally suited for kayakers and small boaters. They combine many planning and navigation tools into a single comprehensive resource. Imagine combining a marine chart with a topographic map, a current atlas and a guidebook. Then add some 3-D shading of the landscape, a profile of the seafloor and other extras for the discriminating navigator.
