Harborline: Marine Charts

Harborline is a chart plotter for your phone, tablet and watch, built from NOAA and USACE ENC data for US waters. CHARTS THAT KNOW YOUR BOAT • NOAA ENC charts drawn the way mariners read them: soundings, depth contours, buoys and beacons, light sectors, restricted areas. • Set your draft and safety depth: a bold safety contour; isolated dangers stand out. • Overscale warning; tap objects for details. • CATZOC layer: survey reliability of each chart area. • Day, dusk and a red night palette. NAVIGATE • Live position, SOG, COG, heading and a COG vector. • Build routes and follow them with DTW, BTW, ETA and XTE alarms. • Advisory auto-routing (Premium) on NOAA ENC Band 4+ charts by draft and air draft; doubtful legs are flagged. Check every leg. • Departure planner (Premium): when to leave by forecast wind, waves, current, tide and daylight. • Leg list with distance, bearing, time and ETA; fuel (Premium). • Tracks, waypoints, GPX; export to a plotter's SD card (Premium). • Man overboard with one tap, bearing and distance back to the spot. • Anchor alarm with an adjustable swing circle, also in the background. • Apple Watch and Wear OS: instruments, next waypoint, man overboard, anchor alarm. RIVERS AND THE ICW (Premium) • USACE Inland ENC, Lower Mississippi and Lower Ohio: river miles, locks, gauges, a depth datum badge; no auto-routing. • USACE channel surveys, bridge opening schedules at your ETA and NOAA Coast Pilot. Information only; may be out of date. Confirm bridges on VHF. INSTRUMENTS AND AUTOPILOT (Premium) • NMEA 0183 over Wi-Fi or Signal K: depth, speed, wind, GPS. • Personal depth contours drawn live from your sounder (information). • Send the active route to your autopilot; stay at the helm. • AIS targets and CPA/TCPA alarms with an AIS receiver on board. Advisory: not every vessel transmits AIS; keep a lookout. • Online AIS: delayed, may be incomplete, no alarms; never replaces a lookout. The visible map area is sent to our server. • Your boat's instrument and AIS data stay on your device. WEATHER AND WATER (Premium) • NOAA tides with 24-hour and 7-day graphs; current arrows. • Wind (NOAA HRRR, GFS) up to 7 days; waves. • NWS marine warnings and zone forecasts over the chart. OFFLINE (Premium) • Chart packs by region for no-signal use, updated each edition. • Online chart plus a cached corridor along the active route. • USDA NAIP satellite imagery, for information. WITHOUT A SUBSCRIPTION Man overboard, the anchor alarm (also on the watch) and your position always work; your routes, tracks and waypoints stay viewable and export as GPX. The nautical chart needs the subscription. COVERAGE US waters only: coasts, the Great Lakes, the Intracoastal Waterway and the Lower Mississippi and Lower Ohio. Not the Bahamas or Canada. HARBORLINE PREMIUM — TRY 7 DAYS FREE 7 days free if eligible, then an auto-renewing monthly or annual subscription.

Continued use of GPS in the background can decrease battery life.
