Live NOAA vector charts with SST, seafloor relief, four wind models, radar, currents, and every AIS vessel on the water. The map behind this text is live — so is every demo below.
Fish hold on edges — temperature edges, bottom edges, current edges. ChartNav puts all three on the same chart.
Satellite SST rendered on the chart. Work the break, not the blank blue middle. Chlorophyll ocean-color stacks on top for the productivity edge.
NOAA BlueTopo bathymetry with hillshade — banks, ledges, and holes read like terrain. This is Stellwagen Bank, live tiles.
Real NOAA ENC — soundings, buoys, lights, wrecks, depth tints you can re-threshold live. Soundings in fathoms, feet, or meters. Inland ENC covers the rivers.
USACE hydrographic surveys drawn on the chart — the surveyed depths of channels and harbors, with the source PDF one tap away.
NOAA CO-OPS predictions for Gloucester Harbor, drawn as they stand right now. The amber line is this moment; fish the turn, not the clock.
Four primary models side by side, real radar, live lightning, and the GOES view from orbit. When the models disagree, you see that too.
GFS, HRRR, NBM, and ECMWF ingested from the source and compared at your spot — this meteogram is Stellwagen Bank, right now.
Real WSR-88D scans — not a smoothed tile layer. This loop is the Boston radar's last eight sweeps, on the chart.
Blitzortung strikes, 60-minute rolling window, with radius alerts so a building cell never surprises you offshore.
GeoColor, true color, and night IR straight from GOES-19, refreshed every five minutes. This is the latest frame.
Live AIS from a worldwide receiver network — including our own antenna — and a 30-day time machine over your grounds.
Scrub any window in the last 30 days. Watch who set up on the ledge at 0300, how long they held, and when they ran for the barn. Below: six real hours over Stellwagen, animated.
NOAA's 1/12° ocean model as a live vector field — set, drift, and the rips where bait stacks up. Particle flow animates it in the app.
Drop-and-drag routes with a depth-safe ribbon, GPX 1.1 export to your plotter — and a Captain's Briefing that reads the tide gates, currents, wind, and daylight for every leg before you go.
Drift radius for the night on the hook. It yells before the rocks do.
Long-press the chart: MOB, anchor, or mark — position fixed at the press.
Share live position with chosen friends. Contact-lost alerts fail safe.
Gale, storm, SCA drawn on their real zones. Fog advisories before the bank.
CO-OPS curve for the station nearest your ledge. Fish the turn, not the clock.
1,480 harbors with live arrivals. A page for every vessel you share water with.
Web in any browser · iPhone & iPad native app · Apple TV boat-dashboard mode for the salon · Apple Watch on your wrist. Marks, routes, tracks, and alarms stay in sync.
SST follows the satellite product cycle; RTOFS currents update on 6-hourly model cycles; radar, lightning, and AIS are live. Every layer shows its timestamp.
Yes — Replay history plays back recorded AIS for any window in the last 30 days, like the demo above. Scrub it over your grounds.
No, and it isn't meant to. Plan here, export GPX 1.1 to your Garmin/Simrad/Raymarine, and run official charts at the helm.
Yes — it's a progressive web app, and native iPhone/iPad, Apple TV, and Watch apps share the same account and sync.
The full chart has all of it, together, right now.
