Official ENC charts. Real conditions. Your boat's own instruments. One app, in your hand.
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 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 all 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: depth areas, contours, soundings, hazards, lights, cables, restricted areas and labels.
CONNECT TO YOUR BOAT — NMEA 0183 AND 2000
Join your boat's network over Wi-Fi and receive live instrument data: speed, depth, wind, heading, position, RPM, fuel and more. Multiple engines, tanks, batteries and other device instances are handled properly. Build your own dashboard from around two dozen widgets — drag, resize, and see the source behind every reading.
AIS COLLISION AWARENESS
See nearby vessels on the chart with closest point of approach (CPA) and time to CPA (TCPA). Configurable safety thresholds, colour-coded risk levels, flashing warnings and escalating alarms help you spot a developing situation early.
TIDES AND CURRENTS FROM CHS AND NOAA
Official Canadian Hydrographic Service and NOAA stations appear directly on the chart. Read current speed and direction, flood and ebb, slack water, turning times, tide height, rising or falling trend, and the next highs and lows — exactly what matters around harbours, channels, narrows and tidal passages.
MARINE WEATHER, ON THE CHART
Animated overlays for precipitation, temperature, wind, gusts, waves, tides and currents, with a full-screen forecast that lines up every marine category on one timeline. Pick the model — automatic, NOAA NWS, or Environment Canada where available.
14-DAY OFFLINE FORECASTS
Download 14 days of rain, wind, wave, tide and current forecasts for the area you're heading to before you leave. Losing signal offshore no longer costs you the conditions.
ROUTES, TRACKS, MARKERS AND ALERTS
Plan multi-leg routes with distance, ETA and fuel estimates, then preview them with built-in simulation. Measure with a multi-leg ruler and convert it to a route in one tap. Record and replay your tracks, and save markers with labels, notes, photos or video. Get alerted for charted Restricted Areas and supported DFO fishing closures — tap through to read the actual rule.
WORKS OFFLINE
Charts cache automatically as you browse, so coverage you've already looked at stays available with no connection. Storage Management shows exactly what's cached and lets you clear it.
ENGLISH AND SIMPLIFIED CHINESE
Weather, tides, currents, station information and offline forecast tools are available in both languages.
SeaVectors aids navigation. It does not replace official paper charts, a proper lookout, or prudent seamanship. Always cross-check.
