Never get stuck under a bridge again! We are pretty excited about the unique Augmented Reality (AR) feature we have just added to our popular SeaNav iOS marine navigation app. Set a SeaNav POI (Point of interest) marker for a bridge (or cable) on the SeaNav map view, set your boat’s Air Draft in SeaNav’s settings (5.5m for our test boat with its mast down) and see this as you approach the bridge in SeaNav’s AR view on your iPhone or iPad:-
This is one of the 3 low bridges we have to pass under on a tidal river around High Tide (12m at Springs) to get out to sea from our mooring. With the horizon line lined up with the sea level at the bottom of the bridge, the bold red line shows the height of your boat at the bridge. With the latest iOS camera APIs we can get the FoV parameters for any iOS device which allows us to do the relative drawing. The SeaNav POI feature comes included with our free version of the SeaNav App, Air Draught is now included as part of the SeaNav Pro In App Purchase feature ($10) which adds Augmented Reality and live ship AIS positions.
We have received a lot of requests from our SeaNav users wanting to mark a favourite fishing or diving spot, beautiful anchorage etc. You can now do this in SeaNav with the new Favourite Places feature. Add custom markers to your charts for places you want to remember, share with friends or even better share with the rest of the SeaNav community. There are several types now available:-
- fishing spots
- diving locations
- favourite anchorage spots
- race markers for club racing
Set up a series of race marks or route for your local club and share with all. Update them in an instant if there is a change in the wind. Add a reminder for which VHF channel to call a marina or VTS. Use your local knowledge to mark a hazard to warn other users. Let people know about a service or marina that is available and provide recommendations/ details/ contact numbers in the description. Note the clearance under a low bridge that is not marked on the chart.
You can add a title, description and a photo for a POI. You can backup/share your POIs via email and dropbox and now you can also share POIs straight from the app with the whole SeaNav community via the SeaNav web page SeaNav Routes and POI service . You can share routes and download them from the SeaNav pages too.
You can read more about how to use the POI and Routes features in our SeaNav user guide on the web or in the App under Settings/Help, FAQ and Demo.
The SailTimer WindInstrument is completely wireless, no power of data lines, so the install is far simpler than for other marine wind vanes. It is the first masthead anemometer with a digital compass built into the wind direction arrow so you get true wind direction even when docked or at anchor. It sends the wind data via bluetooth and is solar powered with 24 hour running. The WindInstrument if fully weather and waterproof (submersible) and has innovative wind cup blades design to maintain equal accuracy when sailing heeled over.
