Question 1786Navigation General
70% to passAt 0000 you fix your position and change course to 270°T. At 0030 you again fix your position, and it is 0.5 mile east of your DR. Which statement is TRUE?
A
The set is 270°, drift 0.5 knot.
B
The set is 090°, drift 0.5 knot.
C
The set is 270°, drift 1.0 knot.
D
The set is 090°, drift 1.0 knot.
AI Explanation
The correct answer is D) The set is 090°, drift 1.0 knot. To arrive at this answer, we can use the information provided: - At 0000, the vessel's position was fixed and the course was changed to 270°T. - At 0030, the vessel's position was fixed again, and it was 0.5 mile east of the dead reckoning (DR) position. This means the vessel experienced a set (current direction) of 090° and a drift (current speed) of 1.0 knot, which caused it to be 0.5 mile east of the expected DR position. The other options are incorrect because they do not match the given information about the vessel's position relative to the DR.
