● Depth, speed, course, wind, location, rudder, rpm. More instruments in future versions.

The AIS screen shows relative position, speed and course for nearby targets that the on board AIS receiver is reporting. A minimum safe distance can be used to show warnings about potential collisions. The relative direction of travel of targets is shown in colours to indicate relative position in 5, 10 and 20 minutes.

● Relative course and speed, collision detection, forecast position.

Works with many WiFi enabled AIS transceivers and boat devices like Digital Yacht iAIS, SailTimer Windvane and Brookhouse iMUX.

New in version 2.20 of Chart Navigator, charts for Australia are available in three sets:

• The north east and Barrier Reef: Cape York to Brisbane including the Great Barrier Reef and Whitsunday Islands.

• East and south east: Brisbane to Melbourne including Sydney.

• GPS in background.
• Boat heading line.
• Route reverse.
• GPS chart search.
• Multi-format import/export for routes, waypoints and tracks (GPX, CN, KMZ).

- The App is free to start with. The initial mode is ‘day predictions’.
- You then go to Tools>App extensions and get the year, which will allow the app to make predictions beyond one day. In future years you update year on year.
- The 7 day restriction in European countries (UK/Ireland/Germany, Netherlands, Belgium, Portugal) can be removed with a hydrographic licence. This is done only once, and will remain valid in future years.
- NB: for France a hydrographic licence is always needed

Please note that the 7 day restriction in Europe (1 day in France) blocks predictions for 2013 until the beginning of 2013. Predictions will work from that date.

On 26 August 2012 Wayne Soutter became the first swimmer to ever make the crossing between the Mull of Kintyre and Northern Ireland, taking 12 hours of incredible stamina and perseverance to overcome the challenges of the North Channel tidal streams and very rapidly worsening weather. The route and feeding schedule had been carefully planned ahead but the conditions of the day took over at dusk when the wind picked up to F5-6, the sea became rough in swell of 3m and landing south of Fair Head became impossible. Tides of 3-5 knots swept Wayne and landing finally took place at Kinbane Head, on the western side of Ballycastle Bay. Huge congratulations to Wayne!

The image is from the track captured on the day by Carlos using Chart Navigator.

Historic swim from Mull of Kintyre to Northern Ireland

Many thanks to Lisa at the National Ocean Service who kindly provided a detail tidal stream model. Congratulations to the support team of Sean, Joe and Gerard from the Community Rescue Service who steered the boats and provided invaluable local knowledge and hospitality, Bernie ashore who tirelessly kept everybody around the world abreast of events (and who often also corrected our data in the frenzy of communications), friends Paul, Johnny and Mark who maintained the swimming and feeding schedule and provided Wayne with ongoing support, Gary who monitored and recorded the event, and Carlos who put his sailing and tides knowledge plus app to use for the navigational plans.

Users of 2011 Chart Navigator apps can migrate to the 2012 charts at a reduced update price.
