Greg, Totally agree. For coastal pilotage, I do find a horizontal sextant ( Davis 3 plastic great for this) perfect for taking extremely accurate bearings from shore marks. Much better than hand bearing compass. So the joy of sextant skills works for local sailing, not just CN. (see Burch book on plastic sextants. Perfect) Francis -----Original Message----- From: NavList@fer3.com [mailto:NavList@fer3.com] On Behalf Of Greg Licfi Sent: 02 October 2018 18:46 To: francisupchurch@gmail.com Subject: [NavList] Re: Susceptibility of GPS to CME, Rationale for CN? Hello All, it has been a long time since I have posted a message to this group, I love the science and math of CN and include it in my living history demos as part of the Huntington Milita (circa 1775) But speaking practically, how many of us are voyaging across an ocean? I have a 28 ft sailboat and do coastal navigation all the time. Is CN going to help me in long island sound? or on the long island expressway? I own a sextant, I practice with it for the fun of it. I demo period CN with the H.M. as much as I love CN (and I do) I feel knowing how to read a chart, get a good weather briefing, and doing do- diligence planning etc. is what makes for a safe voyage or trip.
