At 0000 you fix your position and change course to 090°T. At 0030 you again fix your position and it is 0.5 mile east of your DR. Which statement is TRUE?
AI Explanation
The correct answer is A) The current is easterly.
The reasoning is as follows:
1) At 0000, you fix your position and change course to 090°T.
2) At 0030, you fix your position again and it is 0.5 mile east of your DR (dead reckoning) position.
3) This means that the actual position is east of the expected DR position, which indicates an easterly current pushing the vessel off course.
4) The other options are incorrect because: B) the current is not necessarily perpendicular to the track line, C) the drift speed cannot be determined from the information provided, and D) altering course to the right would not necessarily regain the track line if the current is easterly.
