Calculating Course To Next Mark - Suunto M3 User Manual

4. CALCULATING COURSE TO NEXT MARK

Setting the bearing to the next mark on the race is sometimes difficult due to poor
visibility. Suunto M3 allows you to calculate the bearing to the next race marker in
advance, before you reach the turning point. This way you can steer to the correct
direction as soon as possible.
The calculation is based on the standard turning angles (30°, 45°, 60°) depending on
the race course.

1.Steer directly toward the first mark and
check your current bearing from the boat
compass.
Example: the bearing to the first mark is 15°.
2.Adjust the Suunto M3 rotating bezel so that
your bearing is parallel to the black triangle
on the inner ring.
