- Seamless fast panning and zooming across charts.
- Route Planning and tracking with Waypoints, SOG, COG, ETA etc.
- Charts work offline

SeaNav uses the latest Digital Vector charts providing a wealth of benefits and advantages over 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.
SeaNav lets you measure distances and bearings and record waypoints on routes. When at sea, the app’s Sailing HUD shows your position, 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 collision alerts.
SeaNav is also available for iOS, so you can plan a route on your Mac and share the route with your iPhone or iPad.
Real-time route navigation requires a GPS location.
Inexpensive 3rd Party units are available to add these accurate location capabilities to your device. SeaNav works with Bluetooth and serial GPS units, and those which provide location or AIS service via TCP or UDP or TCP, including devices from Lowrance, Simrad and B&G GoFree.
Your purchase of SeaNav includes 12 months free updates to the included US chart set.
GPS only required for real time route navigation. Optional Real time AIS, Tides and Weather information require an active internet connection.
Please note that continued use of GPS running in the background can dramatically decrease battery life.
NOT FOR NAVIGATION
This program is distributed in the hope that it will be useful. SeaNav should only be used for basic navigation reference and should not be solely relied upon to determine precise locations, proximity, distance, or direction.

Ratings and Reviews
Far short of the SeaNav iOS app
As brilliant as SeaNav for iOS is, imho, SeaNav for Mac is, well, that much NOT brilliant. Even the iOS app is not perfect (e.g., no way to copy routes, then edit them, as an efficient way to make new, similar routes; placing route waypoints is tedious when your finger obscures the exact placement). I was hoping the Mac app would let me bridge those very minor annoyances. Not only was I completely wrong, but the Mac app lacks many of the features and much of the usability of the iOS app. Many examples; here’s one: to relocate a route waypoint, you can’t just click-select and drag. Instead, you’ve got to manually enter GPS coordinates for the new waypoint location. Seriously? Another: I can plan plan routes on NOAA raster charts; these digital/vector charts are skimpy on detail, and the disappearance (or slow appearance) of certain aids to navigation at different zoom levels, or depending on whether the Preferences window is open (when everything disappears), is unnerving. I’m afraid this product is not suitable even for armchair-at-home route planning.
rip off… do not buy this product
what a useless piece of software, I wish you could get a refund
Useless for what I wanted.
What I hoped to find was an inexpensive app for my Mac that would let me define waypoints on nautical chart so that I could then transfer them to my iNavx on my iPad. Unless I missed something, this app will only support waypoints within the context of a route. The concept of a stand-alone waypoint doesn’t exist. When I imported a bunch of stand alone waypoints that I had previously defined in iNavx, the app created a route to connect them all. Not at all what I had hoped for.
With Family Sharing set up, up to six family members can use this app.
