  • Very good navigation app Nov 18, 2020

    By MV Kinnikinnick
    I’ve used SeaNav and Boat Beacon for six years, extensive offline use in British Columbia and Washington. Of the six or seven IOS marine navigation apps I’ve owned, it’s the best and most enduring. Well maintained and very responsive tech support.

    Purchased app yesterday and initially worked perfectly, then my iPad wouldn't show position on SeaNAv. Strange. I emailed Steve Bennett @ Pocket Electric (the developer) and I had an email back from him this morning. There's a known bug in the llatest bersion of iOS software that prevents the iPad from accepting location from the extenral GPS (in my case, a Dual). The fix is on the iPad: (1) turn off location services on iPad; (2) reboot iPad; (3) wait 5 seconds and turn iPad on; (4) turn location services on. This may need to be done whenever the problem reappears. Let's hope Apple fixes this soon. Anyway, the SeaNav app is outstanding and a real bargain for the recreational boater, in my opinion. And the quick, accurate and friendly tech support seals the deal for me!

    Works best on iPad 3 with cellular/wifi as this iPad 3G has a GPS assisted capability whether connected or not to a cellular network. IPad 2 wifi (no cellular) dees NOT have a GPS Satellite Receiver in them so you would need to add a GPS receiver to an iPad 2. I tried using a Verizon Hot Spot Cellular with iPad 2 and neither worked, nor did Apple Maps or Google Maps. There are no cellular towers in the middle of Lake Michigan, so the triangulated cellular cannot function on a iPad 2. You end up sliding along the shoreline and never go out into the Lake. The same problem happens with Apple Maps and Google on an iPad 2 with wifi. Apple Tech Support acknowledges that they are having problems with Apple Maps and today acknowledged issues reported with SeaNav and BoatBeacon, both sold through their AppStore because of the lack of a GPS receiver in the iPad. I took back my iPad2 wifi and picked up a iPad 3G which allows SeaNav & Boat Beacon to work out on the water. The Technical Support and Management at SeaNav/Boat Beacon provided excellent support and personal attention to my concerns and answered all my help requests. A+

    Love the look and feel of the charts. Easy to read. Zoom in and out makes my onboard Raymarine software/equipment a relic. Use in conjunction with Boat Beacon (app). This will give you real time AIS!
  • Very cool app! Jul 25, 2013

    I also have boat beacon that overlays AIS data on these nautical charts and its great to watch, especially during meetings when you'd rather be on the water :)

    The app is crisp and responsive on my 4th gen iPad -- and the AR feature was a huge help in confirming landmarks while sailing through the fog along the Monterey coast.

    This app saved us last night in the fog. Got home safe thanks to this excellent app!

    This app is truly amazing. It automatically couples with other apps, like the AIS beacon app, et al.

    Google maps is better
  • Misleading Aug 30, 2013

    By Media-amp
    App is suppose to cover all US charts yet none of the lakes in my area show up. In fact, none of the lakes in my state show up, and we are talking some rather large bodies of water. The only body of water to show up is a floodplain called little blue river which isn't even navigable, lol. App should correctly read only select US bodies of water, not ALL U.S. charts. Waste of $10. Navionics is much more complete.
  • Crashes!!! Sep 29, 2013

    By Moemoe33
    when you set sail to a point it crashes and then you have to start all over. Adding spots should be simple but its not, (you should be able to tap in boat position and add your fav spot), zoom in out is app took a time to load or freezes!
  • Not for iPhone! Apr 4, 2015

    I sail Alamitos Bay in Long Beach, CA. Although I have Anchorages layer OFF, the chart still indicates all anchorages. So many are shown that they overlap and are unreadable. On my iPhone 6 Plus, the chart is useless. Tech support claims that the anchorages are the names of the 'water areas' and will show even with the Anchorages layer turned OFF. $30 bucks out the window, as far as I'm concerned.
  • Needs work Sep 19, 2013

    It would be a great app IF it would use iPad internal gps. At the moment it requires you to connect to external gps! How stupid is that?! I used version of this software back on PC. Back than I understood need of external gps. Not theses days. Please fix it. Meantime I will stick to iSailor.
  • Slow to the point of being unusable Oct 17, 2013

    By Layr Layr
    The slightest move on the chart causes a 5-20 second wait for the map to redraw itself. Zooming out makes the map unreadable for at least as long. Simplifying the map only helps a little bit...still too slow to use. The charts are way too busy graphically speaking-very hard to even find a channel with giant marker icons. The only good thing is that is coordinates with boat beacon, a very good app. Get Navionics. 1000 times better.
  • Poor & slow Apr 1, 2015

    Crash & calibrate,seems that's all I do with this app. This app is not even good for recreational boating. Don't waste your time & money.
  • Crash Oct 10, 2013

    Will not run on my 124g iPad3 more than two minutes before crash.
