A, B and C are three ships. A compass is a tool for finding direction. A simple compass is a magnetic needle mounted on a pivot, or short pin. The needle, which can spin freely, always points north.

Rich - Please read the FAQ page. Great site! I have a what I think is a pretty easy compass question for you. Say I am standing on the equator, and I am facing North holding a compass. And I turn right 90 degrees and face due East, and adjust the compass dial until the North mark and the Orienting Arrow are lined up with the North end of the needle. My goal is to walk exactly in a straight line East on the equator.

They are north N , east E , south S and west W. When using a directional compass, hold the compass so that the point marked north points directly away from you. Note that the magnetic needle always points to the north. The true bearing to a point is the angle measured in degrees in a clockwise direction from the north line.

We will refer to the true bearing simply as the bearing. The bearing of a point is the number of degrees in the angle measured in a clockwise direction from the north line to the line joining the centre of the compass with the point.
