SeaNav lets you explore, plan and navigate your boating trips in real time and outstanding high-resolution using Digital Vector Marine charts derived from the latest NOAA and UKHO data providing coverage across the US and Europe (USA, CA, UK & IE, Germany, France, Benelux, Denmark and Spain). Raster charts for FI and NZ. - Vector charts - all buoys, lights etc. are tappable - Seamless fast panning and zoom across charts - Route Planning and real-time tracking - North up and course up displays - Offline charts - Configurable layers - Built-in tutorial mode with full features including charts and AIS - Tides and Weather - Live AIS Ship positions and collision alarm (optional IAP) - Import and share routes and POIs via email and Dropbox - Live Augmented Reality camera view (optional IAP) plus FLIRONE night vision support. - Includes free Apple Watch app - NMEA Depth, Wind Speed and Direction gauges - Raster (RNC) charts for US (NOAA), FI and NZ (LINZ) (IAP) The free version includes all our navigation and trip planning tools. High resolution vector charts are available by In App Purchase (IAP) with free chart updates for a 12 month period. Vector charts provide many advantages over traditional raster charts. Buoys, Lights, Bridges, Depth Contours, Depth Soundings, Rocks, Anchorage areas, NOAA Weather Buoys etc. are all selectable and have real time distance, bearing and detail information. Turn off layers to de-clutter the display and only show what is important at the time. Tides, moon and sun times and weather are also all available at your fingertips. In-app tools let you measure distances and bearings and record waypoints on routes to sail. When you are out at sea, the app’s Sailing HUD shows your position on the route, Course over ground (COG), Speed over ground (SOG), Vector Made Good (VMG), Estimated Time of Arrival (ETA), Distance and bearing to next Waypoint. Waypoint reached alerts, auto-routing to the next waypoint and flashing collision alerts (with AIS). Unique AR view mode (IAP) allows you to view buoys, lights, ships, waypoints, route and track overlaid on your iPhone or iPad live camera view. With "AR LockOn" you can select a target on the chart and then be guided to it in the AR camera view. You can also see at night and in the fog with the FLIRONE Infra-red camera. Free SeaNav Apple Watch app. External NMEA GPS, AIS and Wind data over Wifi. Requirements: GPS only required for real time route navigation. Optional Real time AIS, Tides and Weather information require an active internet connection. WiFi-only iPad or iPods will need an external GPS receiver for navigation. Please note that continued use of GPS running in the background can dramatically decrease battery life.

  • Excellent program

    By Simeoniii
    Had this installed for a while and I’m now beginning to use it. Integrates well with my Wind Instrument. The building of routes and importing waypoints stumped me but after reading the Help document. After working with the app and companion app Boat Beacon, I am really impressed. Excellent response from help desk/support and they want user feedback to guide their future app updates. I am changing my rating from 4 to 5 stars.
  • Excellent nav tool

    By Online Lerner
    Best app for marine navigation bar none! In-app purchases are also well priced and actually increase functionality and usefulness. Must buy for boaters, especially big water.
  • Great for this newbie

    By Mazeppa
    I am a novice boat renter. This app really helped me stay on course in unfamiliar waters.
  • By far, the best sail nav app available

    By iPhoneGuy321
    Of all the apps I've tried in this genre, this is the very best one and well worth the $$. The vector maps are amazing in detail, easy to read and super fast even on older iOS devices (aka iPhone 4). Great in--route tracking and tracing. Amazing HUD. Fabulous for nighttime navigation. Active captain integration is terrific as well. My only wishes would we course integration with nmea 2000 devices (autopilot, etc). as well as easy export import of route plans between iOS devices.
