Four-Point Bearing (Bow and Beam)

Definition

A point is 11.25 degrees, so four points is 45 degrees. Log the distance run from when an object lies 45 degrees on the bow until it is abeam at 90 degrees. That distance equals the beam range, giving the distance off at the moment of the beam bearing and hence a fix combined with the beam bearing itself. It is popular because both angles are easy to judge accurately, but like all such methods it degrades badly in a cross tide.
