What is the compass course of a vessel heading NNW?
• Cardinal and intercardinal points on the compass (N, NE, E, SE, S, SW, W, NW) • How 32-point compass bearings are spaced in degrees around the circle • Relationship between a named point like NNW and its position between N and W in degrees
• First, convert the full 360° of a compass into how many degrees separate each of the 32 points. What is that spacing in degrees? • Figure out the degree value for North and for West. Then determine where NNW lies between them in the 32-point system. • Compare your calculated degree for NNW to the options and pick the closest exact match.
• Be sure you’re using true compass bearings in degrees, measured clockwise from North (0°/360°). • Confirm how many degrees per point there are in the 32-point compass (this is critical). • Double-check that NNW is the point between NW and N, and not confused with neighboring points like NW by N or N by W.
