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
