Explore the Northeast Coast with Precision: Coverage from Cape Cod to St. John

Navigate the intricate waters of the Northeast Atlantic with confidence using these advanced marine charts. Spanning from Cape Cod, Massachusetts, up to St. John, New Brunswick, this chart set delivers razor-sharp detail for key hotspots. Whether you're docking in bustling Boston Harbor, threading through the channels around Portsmouth, New Hampshire, or anchoring near Portland, Maine, every twist and turn is mapped out. Venture inland along the Kennebec River to Augusta or the Penobscot River toward Bangor for freshwater adventures, or island-hop to Martha's Vineyard, Nantucket, Grand Manan, Mount Desert Island, and Calais, Maine. Cross into Canada for St. Mary's Bay and Yarmouth, Nova Scotia. Bathymetric data illuminates George's Basin, Franklin Basin, and the Northeast Channel, revealing underwater contours vital for safe passage and prime fishing grounds.

Advanced Features for Safer, Smarter Boating

These charts stand out by blending Garmin's proven reliability with Navionics' cutting-edge data, creating a seamless experience on compatible chart plotters. Forget guesswork—features like high-resolution relief shading and Auto Guidance transform your display into a virtual pilot, helping you avoid hazards while maximizing enjoyment on the water.

Auto Guidance: Your Personal Route Planner

Set your preferred depth and overhead clearance, and watch as intelligent algorithms plot the optimal path. Ideal for dodging shoals near Nantucket or navigating busy traffic in Boston, this tool simplifies complex routes, giving you more time to focus on the horizon.

High-Resolution Relief Shading: See the Seabed Like Never Before

Color gradients and shadows reveal bottom structures with stunning clarity, far surpassing traditional contour lines. Spot drop-offs, reefs, and ledges effortlessly—perfect for anglers targeting striped bass around Mount Desert Island or lobstermen scouting pots in the Northeast Channel.

Depth Range and Shallow Water Shading: Stay in the Safe Zone

Customize up to 10 depth ranges to highlight your target zone at a glance, or shade shallow areas to steer clear of trouble. With contours as fine as 1 foot, marinas, swamps, and narrow canals become navigable playgrounds rather than risks.

Immersive Visuals: Satellite Imagery, Aerial Photos, and 3D Views

High-definition satellite overlays and aerial photos pinpoint marinas, bridges, and landmarks with pinpoint accuracy. Dive deeper with MarinerEye for an overhead perspective or FishEye for underwater views, enhancing situational awareness from every angle.

Why Northeast Boaters Rely on These Charts

In a region notorious for fog, tides, and rocky coasts, superior charting isn't optional—it's essential. Fishermen praise the detailed bathymetry for uncovering hidden wrecks and structures teeming with cod or haddock. Sailors appreciate the integrated data for plotting safe passages amid shifting sands off Cape Cod. Powerboaters love the Auto Guidance for weekend getaways to the Fundy Bay area. Loaded on a microSD/SD card, setup is plug-and-play with Garmin chart plotters, ensuring you're ready when the tide turns.
