A vessel intends to travel at a course due South. The movement of the sea current is from SE. At what course must the vessel stir?

E
NE
SE
NW
SW

The vessel must stir at a course of SW.

To determine the course at which the vessel must steer, we need to consider the movement of the sea current and the intended direction of the vessel.

In this scenario, the vessel intends to travel due South, and the sea current is from the Southeast (SE).

To counteract the effect of the sea current and ensure the vessel maintains a Southward course, the vessel needs to steer slightly to the East (E).

Therefore, the correct course for the vessel to stir is E (East).
