Question 1781Navigation General70% to pass
Discounting slip, if your vessel is turning RPM for 10 knots and making good a speed of 10 knots, the current could be _______________.
AI Explanation
The correct answer is C) slack.
If the vessel is turning at a rate of RPM for 10 knots and making good a speed of 10 knots, it means that the current is not affecting the vessel's speed. In other words, the current is slack or negligible. This is because the vessel's speed through the water (10 knots) is equal to its speed over the ground (10 knots), which indicates that the current is not adding or subtracting any speed from the vessel.
The other options are incorrect because:
A) and D) imply that the current is affecting the vessel's speed, which is not the case here.
B) would mean the current is against the vessel, but the vessel is still making good 10 knots, which is not possible.
