    Re: Practice CN on cruise ship

    Norm, if you mainly want to check your progress with the sextant, I'd suggest Navimatics "Celestial" app; ($20 on Apple and Android). Its one quirk is you enter Index Error, rather than Index Correction. That is IE on the arc is entered +; IE off is entered -. 

    I use it in teaching and like it because it displays Ha, Ho, and Hc as well as Zn and Intercept.

    I, alas, must board my cruise ship the day of your class in SF. I bought a plastic sextant to practice at sea. Ill have my laptop, so what should I download in order to gather my data and see how close I come to my actual location? I know it will not be accurate, but I want the thrill of taking data and reducing it. I'd like not to pack an almanac if possible, relying on downloaded versions, if possible. I'm excited. I know the principles but not the practice?
