The very technology that seemed to question the viability of the practical use of the Sextant is now the tool that makes the Sextant once again an important navigation tool for the small boat cruiser as well as the professional navigator. Traditional companion tools for the Sextant were the chronometer, almanac, sight reduction tables, worksheets, and plotting board. All of these tools were required and were tedious and time consuming to work with and maintain. Now enter the i-phone app “Star Pilot”, hand held computer with dedicated sight reduction program and the inexpensive digital watch. Now the procedure to get a fix becomes: Take the shot with the sextant, observe the time with the digital watch, enter the observed information in the i-phone app or the computer program and mark the fix on the chart. Granted the i-phone is also a GPS tool but the i-phone app will still work even if the constellation of GPS satellites fell out of the sky.

For the Sextant Cruise, we will have aboard, Sextants, handheld computers and will demonstrate the iphone app. If you have an iphone or ipod that you wish to use, please load the app. STAR PILOT. There may be other apps. available but this is the one we will be demonstrating.
The cruise will sail to the Chesapeake Bay in search of a good sea horizon. We'll take a series of sun shots to reduce, using programs that will give you feedback on your sextant skills and show you how easy it is to use a sextant.
