You could also go one step further and make a 6dB collinear like this from Neil Arundale (I have made and used one of these too and it compared equally with a £120 commercial collinear).
SeaNav now has seamless official raster (RNC) charts available for download for the whole of New Zealand and Finland. You can use all SeaNav’s route planning, POI and live navigation tools and display on top of the charts like you can with the existing vector charts.
Charts are automatically installed and saved as you browse and zoom in on SeaNav and you can also download all the charts in a map region for offline use ( no internet connection) in a single go.
Zoom right in to get fantastic detail on the charts. Here’s the marina in Auckland with live AIS ship positions overlaid:-
Here is Finland showing the chart coverage (outlined in red):-
and here is Helsinki zoomed in about half way:-
You can find the new raster charts listed under SeaNav/Settings/SeaNav Chart Store in the new “Raster section at the bottom”. A yearly subscription also provides ongoing chart updates from the Finnish and New Zealand Hydrographic offices.

Danish charts are now available in SeaNav. The vector marine charts are licensed and derived from the official Danish Hydrographic Office data. These cover the whole of the European Danish waters. Please see the coverage map below.
Coverage Map for Danish charts:
Here is a close up on the iPhone showing the approach to Copenhagen. Being vector charts, all chart objects are tappable to give more information. This includes names and types as well as distance and bearing from your position. Sectored lights also show the colours, range and sector angle when tapped.
SeaNav also has complete live Ship (AIS) coverage for the whole of Denmark. Here is an example in the Aabenraa Fjord showing the Maureen S. just departed on her way to Germany.
SeaNav now has UK, IE, NL, BE, FR, DE, ES, US and CA charts available with complete coverage across the English Channel and we now have continuous coverage from Nantes in France through Belgium and the Netherlands, across Denmark and Germany including the German inland waterways. Current European chart coverage is outlined in red below.
Norwegian charts are also available for free in SeaNav’s sister app, NaviPlotter by Nautisk (same app as SeaNav but with different branding and additional Norwegian charts from the Norwegian HO).
The Danish charts and others can be obtained via a simple In App Purchase (IAP ) in SeaNav and SeaNav UK. All SeaNav charts are regularly updated while you have a valid chart subscription in place. You can read more about SeaNav and how to download our free version here – SeaNav
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.
There is more about SeaNav POIs here
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 :-
“Alexa, ask Boat Beacon my position”
“Sarita is travelling North East at 6 Knots in the English channel currently 5 miles south west of Plymouth”.
Or ask for “exact position” and hear : “Sarita. Latitude 52 degrees 1 minute North, Longitude 1 degree 52 minutes 34 seconds West, course 55 degrees true, speed 5 Knots.”
You can see a short 19s video clip of the Boat Beacon Alexa skill in action here :-http://boatbeaconapp.com/BoatBeaconAlexa.mp4
Just ask Alexa to register your Boat Beacon 9 digit BBSI number (without the BB prefix) to associate the Alexa Boat Beacon skill with your own Boat Beacon app and put Boat Beacon in transmit mode (sailing) to update your location, speed and course in real time.
“Alexa, ask Boat Beacon to register 617648992”
Response: “Boat Beacon BBSI 617648992 has been successfully registered. You may now ask for its position”.
You can find your unique Boat Beacon BBSI number at the bottom of Settings/My Boat Details in the Boat Beacon app on your iPhone or Android device. See the iPhone screenshot below.
Friends and family can also use the Boat Beacon Alexa skill to follow your progress when you share your Boat Beacon BBSI 9 digit number with them.
We have lots of other ideas up our sleeves for the Alexa Boat Beacon skill if it proves popular. “Alexa, ask Boat Beacon to alert me on CPA” , “Alexa, ask Boat Beacon to tell me if the wind exceeds 6 knots” and would love to hear your ideas. And if you want to know where another boat is by name or MMSI number you can use our free Boat Watch Alexa skill

How to find your BBSI number
