SeaNav App Comments & Reviews
SeaNav Positive Reviews
Excellent programHad 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..Version: 4.8.1
Intuitive and accurateI have had SeaNav for a year now and have learned to trust it. It is just as accurate as any high dollar system and is easy to use..Version: 5.2
Wouldn’t sail without it!Love knowing what went buy in the middle of the night when anchored. And what’s coming by before I can see it! Catalina 380 Hull 123.Version: 5.4.1

Great helpExcellent.Version: 5.1
By far, the best sail nav app availableOf 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..Version: 3.7

Sea nav great for cruisingI watch the SeaNav app when we are cruise to watch our ship and the current and winds while we travel.Version: 5.4.9
Super appReally like this app and the info on my Apple watch. But above all outstanding support!.Version: 5.2
Useful appWorks great on my iPad. The app has lots of features. Route planning, storage of waypoints, information and reviews of anchorages. You can click anywhere and instantly see the depth at that point. I don't have a cellular connection on my iPad. I bought a portable wifi connected GPS antenna from Bad Elf. The antenna fits in the palm of my hand, and is rechargeable. I then have proper GPS coverage anywhere. I could see where I was 700 miles north of Hawaii. In local waters I connect to my iPhone then I can get live AIS information. I only make this connection when I need it to look at nearby boats. I don't want to eat up wireless minutes..Version: 5.2
First use during 4 day Lake Erie cruiseHi, We just got back from 4 days sailing Port Dover -> Port Maitland -> Port Colborne -> Port Maitland -> Port Dover. We had installed SeaNav and Navionics on a pair of iPads connected to our NMEA 2000 system via a Yacht Devices YDWG-02 server port. SeaNav easily won the evaluation and we did not try to use the Navionics after the first day. An outstanding success! David Bramwell Sailing vessel Eriewinds, Port Dover.Version: 5.1
Great app with accurate Canadien dataI like this supporting app to plan my selling navigation and play back. To the dev team. Keep going on dev..Version: 4.8.1
