donny, sq rt 50 is easy to do in one's head.
besides, it was not a navigational problem. Hey! I'd be grateful if you would stop using me to back up your position. You wrote off my initial answer as being little better than Jax's. I think that you must be feeling a bit desperate if you are now trying to use me in your argument against Jax. I worked out my answer using a Breton plotter, and a bit of paper, at 20 minutes to midnight, on a Saturday, after a meal and a bottle of wine. You used log tables, at 9:30 am. I feel that I have nothing to be ashamed of. I don't consider log tables to be part of the traditional navivator's toolbox. I've done this sort of nav for real, at sea.. .... many times. I do it to within 1* of accuracy. If you need to use log tables, *or* if you need to be able to calculate square roots, then you shouldn't consider yourself to be capable of doing navigation. You are both as bad as each other. Regards Donal -- |
