Four Powerful Base Layers
Switch between map styles depending on your needs — from detailed coastal maps to high-resolution satellite views.
Detailed Coastal Map
Comprehensive street and coastal mapping with full zoom capability down to individual docks and marinas. See roads, landmarks, and coastal infrastructure.
Ocean Marine Chart
Optimized for open water navigation with depth-shaded ocean coloring, coastal outlines, and marine-specific features. The go-to layer for offshore passages.
Topographic View
Detailed terrain and elevation data with contour lines. Ideal for coastal exploration, identifying headlands, cliffs, and terrain features visible from the water.
Satellite Imagery
High-resolution satellite photographs with deep zoom. See actual water color, reef structures, sandbars, dock layouts, and anchorage conditions from above.
Professional Navigation Overlays
Layer critical navigation data on top of any base map for complete situational awareness.
NOAA Nautical Charts
Official electronic navigational charts showing buoys, beacons, channel markers, aids to navigation, depth soundings, and restricted areas.
International Sea Marks
Worldwide navigation symbols and sea marks following international maritime standards. Lighthouses, cardinal marks, lateral buoys, and port signals.
Ocean Depth Contours
Bathymetric shaded relief showing underwater terrain, depth contours, and ocean floor features. Essential for finding fishing structure and safe passages.
Wind Direction & Speed
Real-time wind overlay showing direction arrows and speed data across the map. Plan your route around wind patterns and weather systems.
Wrecks & Obstructions
Charted wrecks, underwater obstructions, and hazards displayed on the map. Know what lies beneath your hull before you get there.
