SeaVectors vs MSI MAP

Official ENC charts. Seabed relief. Marine weather and currents. Your boat’s instruments. One app. SeaVectors brings together official charts, regional current models, marine forecasts, tide predictions, AIS collision awareness and your boat’s NMEA data. Explore full NOAA chart coverage for the United States and high-definition vector charts for the Canada West Coast. Try everything free for 30 days. PROFESSIONAL ENC CHARTS Charts use official S-57 data and S-52 symbology, with day/night palettes and a boat-specific safety contour. Tap objects to read their official attributes. Choose nautical, night, satellite or relief styles and control individual layers. SEE THE SEABED Shaded bathymetry reveals ledges, channels and drop-offs. Coverage includes British Columbia, the US West Coast, Puget Sound, Florida and the US East Coast, with detail down to 1 metre in selected areas. EXPLORE AND SAVE The crosshair identifies charted wrecks, rocks, obstructions, bridge clearances, lights, buoys, depths and bottom types. Charts cache as you browse. Download charts and relief for selected areas before departure, and manage saved data in Storage Management. CONNECT TO YOUR BOAT Connect over Wi-Fi to your NMEA 0183 or NMEA 2000 network for live speed, depth, wind, heading, position, RPM, fuel and more. Monitor multiple engines, tanks and batteries, and build your own instrument dashboard. AIS COLLISION AWARENESS See nearby vessels with closest point of approach (CPA) and time to CPA (TCPA). Custom thresholds, colour-coded risk and escalating alarms help identify developing collision risks. TIDES AND REGIONAL CURRENTS View CHS and NOAA station predictions for tide heights, highs and lows, current speed and direction, flood, ebb and slack. Animated currents use Canadian ECCC CIOPS models and NOAA regional models covering the Pacific and Atlantic coasts, Gulf of Mexico and Great Lakes, plus broader RTOFS East coverage. Nearby station predictions refine local currents where applicable, with Open-Meteo as a fallback. Smooth particles, speed-based colours and legends make flow easier to follow. WEATHER ON ONE TIMELINE Compare wind, gusts, waves, tides and currents in a redesigned panel with coloured curves and animated map overlays. Sources include NOAA NWS, Environment and Climate Change Canada, GEM, NOAA GFS, ECMWF IFS, ECMWF AIFS and Météo-France. Auto and Open-Meteo Best Match simplify selection. Open-Meteo marine forecasts and NOAA GFS-Wave add marine coverage. Open at NOW, keep the selected hour when switching tabs, and return to current conditions with one tap. Save available forecasts for offline access. Coverage and forecast length vary by location, source and time. PLAN AND RECORD Create routes with distance, ETA and fuel estimates, and preview them with simulation. Record and replay tracks. Save markers with notes, photos or video. Receive alerts for charted Restricted Areas and supported DFO fishing closures. YOUR UNITS, YOUR LANGUAGE Choose feet or metres, °F or °C, and knots, mph or km/h. Available in English and Simplified Chinese. SeaVectors aids navigation. It does not replace official paper charts, a proper lookout or prudent seamanship. Always cross-check.

Bring your passage into the app, keep only the navigational warnings that actually touch it, and carry them over to the ECDIS. NAVAREA and coastal NAVTEX warnings are plotted on a world map whose coastline is bundled inside the app — no tile server, and the last warnings you pulled stay readable with no connection. WARNINGS ALONG YOUR ROUTE — MSI PRO · Import a route file (RTZ, GPX, CSV or JSON) and see it drawn under the warning pins · Keep only the warnings within 100, 200 or 300 nm of that route and clear the rest away · Re-fetch every source on demand, instead of the free once-daily cycle EXPORT TO THE ECDIS — MSI PRO Warnings are carried over as latitude/longitude lines with text marks, ready to open on the bridge. · JRC user map (.uchm) — native format · GPX · Furuno user chart (beta) WARNING SOURCES · NGA — worldwide NAVAREA plus HYDROLANT, HYDROPAC and HYDROARC · Coastal NAVTEX, collected automatically from seven countries — the United States (USCG), Australia (AMSA), Japan (JCG/MSIL), Taiwan (MOTC), Hong Kong (Marine Department), Finland (Traficom) and Denmark (DMA Niord) · NAVAREA III — Spain (IHM) · Korea (KHOA) — collected as well once you enter your own free data.go.kr service key in Settings THE MAP · Fully offline vector coastline at three levels of detail, three bathymetry bands, national boundaries and 167 place labels covering major ports, straits and canals · Coordinates and areas are extracted from the warning text and drawn as points, circles, polygons and tracklines · Filter by NAVAREA, by geometry type, and by NAVAREA versus coastal NAVTEX · Place and port search in English, with no network call · Your own GPS position on the chart CHANGE HISTORY Compares each refresh with the one before it and lists what is new, what was cancelled and what changed. DEPARTURE BRIEFING SHEET Print the current list to an A4 PDF. Free. MSI PRO IS A ONE-TIME PURCHASE Not a subscription. Restores on a new device with Restore Purchase under the same store account. The map, the warning list, the change history and the briefing sheet are free. LOCATION GPS is read only when you tap the my-position button, and only while the app is in the foreground. It is used solely to draw your own position on the chart on this device — it is never sent to a server, never stored as a history, and never collected in the background. Decline the location permission and everything else keeps working. There are no push notifications. Refresh is checked when you open the app or return to it. English and Korean. Note — for reference only. Not for navigation. Not a substitute for GMDSS receiving equipment or official notices to mariners.
