SeaNav lets you add individual Point of Interest (POI) at a tap of the screen in the app but what about importing a list of POIs that you already have? We have set up a service to make creating SeaNav Points of Interest from a list of latitudes and longitudes easier and faster. Simply upload a CSV file ( spreadsheet comma separated values) of the POIs using this web link
A SeaNav ready kmz file will be downloaded to your desktop which you can then share and import to SeaNav via email or Dropbox. You can also view the kmz file in Google Earth.
The format for the csv file is very simple and contains one or more lines with:-
name,type (integer 1-6),description,longitude(DD.DDD),latitude (DD.DDD)
e.g. Bass here,3,Good spot,-0.473850,50.291134
The POI types are:
- 1. general
- 2. hazard
- 3. fishing spot
- 4. diving location
- 5. race markers for club racing
- 6. favourite harbour or anchorage spot
- 7. bridge
These set the POI icon to be used as well.
The description can be html markup including an image link e.g.
Be sure to wrap html descriptions in quotes as above.

SeaNav Favourite Places – Share POIs and Routes
and we have a large database of existing and publicly shared POIs including Marinas and Harbours that you can view and send to SeaNav here :-
Here is a quick guide on how to add a new route in SeaNav
Tap the route button at the bottom of the screen.
Long press on the chart where you want to add a waypoint and tap “Add Waypoint here” on the popup.
Add the next waypoint in the same way
And a third and as may as you want and then tap Done when you have finished. You can move the waypoints you have already added using a long press on one to select it and then dragging it to the desired position. You can also edit the exact position (latitude and longitude) later in the Manage Routes view.
After pressing Done the route will be shown on your chart. You can then start sailing the route or tap the Route icon again to Edit or Manage your routes.
Tap Manage Routes to see all your routes and select a different one of manually edit the current one.
Tap the i button next to a route to see more detail. You can also edit the fields on the detailed view. For instance change the route name from Route2 to Cardiff. Tap the i next to a Waypoint to add names for the waypoints and edit their precise latitude and longitudes. You can enter the latitudes and longitudes in most formats ( e.g. Degrees Minute Seconds, Degrees Minutes and Decimal Degrees (e.g. 52.1345) ) and you do not need to enter the degree, minute or second symbols. Here are some examples:-
DM : 28° 52.634 ́ N can be entered as 28 54.634
DMS :28° 52′ 48″W can be entered as 28 52 48W or -28 52 48
This view also lets you export the route via email or dropbox to share with others, keep a backup or share with your iPad or Mac (tap the box with an arrow going upwards from it).

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.
