[Rhodes22-list] Compass

[Saroj Gilbert]

I've never done it, but I have instructions in my coast guard navigation 
text book.... I could send them to you if noone pops up with a quick 
answer... I read through them once and they didn't sound like a lot of 
fun... and frankly... I've never heard of any "casual" sailor taking the 
trouble.... I do believe you have to find some ranges to line up with... and 
of course a chart that shows the orientation of them.
