MotionX-GPS tracks a 40 Mile Downwind Sailing Race

The Race: 40 miles downwind on the Columbia River from Cascade Locks, Oregon to The Dalles, Oregon.
It is a 40 mile West to East course in an area of typically strong prevailing Westerlies.
This year the wind was 20-40 knots! More about the Double Damned Race

Morgan and his team used MotionX-GPS on his Moore 24 sailboat to track the race. It took the them 3 hours and 50 minutes to finish the race for an average speed of 10.44 knots.

This sequence of pictures shows the boat throwing huge spray and then submerging, followed by a near wipe out. They saved the boat from capsizing but as you can see below, their competition was not so lucky.

– Sailing World, April 2009

 

The application has all the essentials a racing sailor would want:
-Digital Compass
-Navigation (waypoint input, latitude/longitude, Velocity Made Good, Speed Over Ground, etc.)

Sailing and Iceboating with MotionX-GPS

Using MotionX-GPS on the iPhone 3G is a great way to look at your sailing races between each race and at the end of the day.  This past weekend two MotionX-GPS user’s sent us their tracks and a few photos.  They both use the AquaPac to keep their phones dry all day.  Jen has been using MotionX-GPS on her 29er sailing skiff and Daniel on his DN Class iceboat.  Daniel says, “I love seeing how fast I went for each race and try to increase my average speed around the race course for each race.  MotionX-GPS allows me to compare my results from one race to the next. It is perfect!”

Navigating back to the Harbor with MotionX-GPS

Tom has been using MotionX-GPS on his boat for navigation.  “Navigating safely back to the harbor after sunset is easy with MotionX-GPS.  I create a waypoint at the harbor entrance and navigate to it when I want to come back.  The Compass screen gives me the bearing to the harbor, course over ground, waypoint distance and ETA so I know when I’ll be back”.
