Hope that wasn't confusing at all
Confusing?!!! My god man that's the most clearest explanation i've read on the entire subject!!!! Thankyou immensely.

I was getting there but started getting confused by some of the posts regarding the second clock above the GMT clock. Some say its local time but gets screwed passing GMT and some say it updates half way between longitudes. I say...HELP!

Just a couple more questions if possible:

1) Is it possible to get lattitude readings by sun spotting using the sextant ? If so then a combination of both Sun and Polaris spotting should increase my position fix accuracy.

3) I should be able to fairly accurately track my course between fixes using distance = speed * time ?

2) In fine weather and calm sea states i should be able to navigate away from a known lattitude (other than heading 90 or 270) before knowing my longitude and still obtain a fix on my position by doing the maths ?

4) In rough sea states I should expect to end up off my intended course due to drift. The ammount proportional to the duration and severity of the rough weather ?

5) If SH3 allows sun spotting then I should be able to correct my position fix by shooting the sun in cloud breaks during a storm...if any ?

6) Is it really necessary to force the helmsman to maintain course during storms and high time compression by constantly clicking on the compass ?

7) What is the max time compression i can use in order to stay within a healthy margin of positional error and why ? (I have also read that the clock goes a bit wobbly during high TC).

Thats it, and once again I really do thankyou for taking the time to answer these probably very obvious questions
