Yeah...it belongs on the part of the thread where I said you need multiple GPS's. A Celestial Fix on lake champlain will put him somewhere in the adirondacks..since it is pretty darn hard to get a horizon there!! (G)
Buy yourself a three arm compass and turn that sextant on it's side and you can place yourself very accurately by measuring the angles between known points. How do you know the points? Accurate DR will give you a very good idea of how the chart you are working with corresponds to what you see. I have found my way quite accurately all over the great lakes using nothing little else. (Occasionally and RDF for an LOP, and the odd measurement of known object heights to get a distance off.) It is certainly less convenient than a plotter but waaay more entertaining!
Edit: And have a couple of GPS around.
