Boat Crewman Practice Test

If water currents are strong, it becomes harder to move upwind.

It becomes easier It becomes harder (upwind) No change It becomes harder (downwind)

Correct Answer:

It becomes easier

Explanation:

Strong water currents act like a moving obstacle when you’re trying to move toward the upwind direction. The boat’s speed through the water combines with the water’s own speed to give progress over ground. When you head upwind, the current pushes back against you, so your net forward motion is reduced. With a strong current, a larger portion of your effort goes into fighting that flow, and you may need to aim the boat more into the current, which lowers the forward component of your movement. In contrast, moving downwind is helped by the current, making it easier. So the statement that you’ll have a harder time moving upwind with strong currents is the correct one.
