'against the compass' means 'in reference to'. So a southerly course = 180 deg, zat right?
but even though I am heading south, my crew will 'pretend' my bow is north = 360 degrees??
and then, when a plane flies from the North - 360 degrees, they will tell me it is on a bearing of 180 degrees, which will tell me its behind me, because I am going south, although they are pretending I am really pointed north?
think I will go and do the washing up!
It WILL make sense to me, the penny will drop - dont give up on me!
