    Blimey! What sources of reference have you been reading?

    oschonrock and the good captain have given very good, experienced based advice on celestial navigation.

    Iím also of the view that a Sextant is a work of engineering pleasure. The process of taking a sight and reducing it to a Position Line is not so difficult to learn but does take practice to improve, just like most things in life. My first sun-mp-sun fix, using a plastic sextant, off wind, about F4 with little swell, was about 30M out (compared to the GPS). As explained well by oschonrock, that would have been perfectly adequate to keep us safe and on-track towards our destination.

    Another good discipline of celestial navigation is the daily compass check. Well worth while, especially in regions with high magnetic variation.

    Interesting watching Jeanne Socrates tactics against the golden globers - quite different with sat/weather/lots modern kit and in no great rush. She seems to have no problem heaving to to wait the weather out & then get in a better position for the next system coming through.

    She's spent a load of time down there so well worth listening to, also likes her JSD.

    Thinking about trying to move on S a bit after present winds have eased somewhat. Would like to get more S ready for next system to pass to North - don't like the look of its very big swells added to its strong winds... Means moving later tonight and then heaving to again once we've arrived at 55S.]
