Question 1937Navigation General

The correct answer is C) 30 minutes before the predicted time of the favorable current. To reach an entrance or strait at 30 minutes before the predicted time of the favorable current allows you to take full advantage of the current. This timing ensures that you arrive at the start of the favorable current, allowing you to maximize the current's effect and improve your vessel's speed and efficiency. The other options are incorrect because arriving at the predicted time (A) may mean you miss the start of the favorable current, and arriving 1 hour after (B) or at varying times relative to the current (D) would not allow you to fully utilize the favorable conditions.
