Navigate the intricate waters from Gloucester, Massachusetts, to New London, Connecticut, with confidence using these detailed coastal charts. This region-specific map set encompasses Narragansett Bay, Block Island, Martha's Vineyard, Nantucket Island, the full expanse of Cape Cod, and extends to general coverage of Georges Bank. Whether you're plotting a course through bustling harbors, dodging sandbars off the Cape, or heading out for offshore fishing, these charts deliver the sharp, reliable data you need for safe and efficient voyages.
Cape Cod's dynamic coastline—with its shifting shoals, tidal rips, and hidden reefs—demands charts that go beyond basic outlines. Here, you'll find enhanced details that highlight key navigation hazards and prime fishing grounds, helping both seasoned skippers and weekend boaters make smarter decisions on the water.
Built on a fusion of Garmin's proven mapping expertise and Navionics' rich dataset, these charts elevate your chartplotter's display to new levels of clarity and functionality. Say goodbye to guesswork and hello to tools designed for real-world boating challenges.
Input your boat's draft and preferred overhead clearance, and watch as the system generates a tailored route. It suggests a path that avoids shallows and obstacles, ideal for threading through Cape Cod's narrow inlets or navigating around Nantucket's treacherous bars. Remember, this is a planning aid—always cross-check with visual cues and local knowledge.
Traditional contour lines are helpful, but relief shading adds depth with color gradients and shadows, mimicking a 3D underwater terrain map. Spot drop-offs near Block Island or subtle humps in Narragansett Bay effortlessly, giving anglers an edge in locating structure for stripers or blues.
Customize up to 10 depth bands to match your fishing or cruising needs, so your target zone pops visually. Paired with contours as fine as one foot, these charts excel in marinas, swamps, and canals where precision matters—like maneuvering into Hyannis Harbor or exploring Provincetown's backwaters.
Set your own shallow-water threshold, and the map shades those zones vividly. Perfect for low-tide runs along Cape Cod's beaches or avoiding unseen ledges off Martha's Vineyard.
Enhance situational awareness with layers of high-res satellite photos overlaid on charts, revealing ports, bridges, and landmarks in stunning detail. For a bird's-eye or fish's perspective:

Cruisers will appreciate the route planning for multi-island hops, while families can relax knowing shallow shading keeps everyone safer.
These charts shine in variable conditions common to New England waters—foggy mornings off the Cape or choppy afternoons in the Bay—providing the edge that turns good trips into great ones.
