About SeaVectors: Marine Navigation
Official ENC charts. The seabed beneath them. Real conditions. Your boat's instruments. One app.
SeaVectors renders the same class of official electronic navigational charts used on commercial ship bridges — full NOAA coverage for the United States, plus high-definition vector charts for the Canada West Coast — then adds seabed relief shading, live weather, official tide and current predictions, AIS collision awareness, and a direct link to your boat's NMEA network.
Everything you see is built on official ENC data. This isn't a street map with water on it.
Try everything free for 30 days.
PROFESSIONAL ENC CHARTS
Charts are built from the S-57 data standard and drawn with S-52 symbology, the same presentation used on ECDIS. Colours, symbols, day/night palettes and a boat-specific safety contour follow the professional standard, and you can tap any object to read its official attributes. Choose nautical, night, satellite or relief styles, and switch individual layers on or off.
SEE THE SEABED IN RELIEF SHADING
Relief Shading mode shades the shape of the bottom from high-resolution bathymetry, so ledges, channels and drop-offs read at a glance. Coverage spans British Columbia, the US West Coast and Puget Sound, Florida and the US East Coast, with detail down to 1 metres in selected areas.
KNOW WHAT'S UNDER THE CROSSHAIR
Move the chart and the crosshair names what it's over: a wreck or rock with its sounded depth, an obstruction, a bridge's clearance, or a light, buoy or beacon with its chart symbol and characteristic. Over open water it shows the depth, the bottom type and the anchorage you're in.
SAVE CHARTS FOR THE TRIP
Charts cache automatically as you browse. Before you leave the dock, pick an area on the chart and download it — charts and relief — for use with no signal. Storage Management shows what's saved and clears it.
CONNECT TO YOUR BOAT — NMEA 0183 AND 2000
Join your boat's network over Wi-Fi for live speed, depth, wind, heading, position, RPM, fuel and more, including multiple engines, tanks and batteries. Build your own dashboard from two dozen widgets.
AIS COLLISION AWARENESS
See nearby vessels with closest point of approach (CPA) and time to CPA (TCPA). Configurable thresholds, colour-coded risk and escalating alarms flag trouble early.
TIDES AND CURRENTS FROM CHS AND NOAA
Official Canadian Hydrographic Service and NOAA stations on the chart: current speed and direction, flood, ebb and slack, tide height and trend, and the next highs and lows.
MARINE WEATHER, ON THE CHART
Animated overlays for rain, temperature, wind, gusts, waves, tides and currents, with a forecast that lines up every marine category on one timeline. Choose NOAA NWS or Environment Canada models where available. Download 14 days of forecasts for your destination before you go.
ROUTES, TRACKS, MARKERS AND ALERTS
Plan multi-leg routes with distance, ETA and fuel estimates, and preview them with built-in simulation. Record and replay tracks, and save marker

Latest updates
2.7
Best-in-class Relief Shading; Advanced Offline Chart Downloader; High Resolution Satellite Imageries; and Following Bug Fixes.
Fixed Local Cache Bug
On some devices some chart elements could stop appearing entirely — the map drew but depths, contours and buoys stayed blank, and restart/reinstalling didn't bring them back. This is fixed, and the app now recovers on its own if it happens again.
Corrected tide times
Tide predictions could be shifted by your device's time zone. Times are
now read correctly, and station tables show the location's own clock.
Cached predictions refresh once after you update, so connect before
heading out.
Knowing which forecast model you're reading in Auto mode
The weather panel names the model behind each forecast, marks where one
model hands over to another, and shows where wave data changes source.
A smoother weather panel
Scrolling the full-screen weather grid is far faster. It opens on the
current hour instead of a day earlier, one tap on the time marker brings
you back to now, and the row labels are tidier.
Place names on Weather Panel
The weather panel now shows where you're looking, alongside the
coordinates.
