Question 691Navigation General

The correct answer is D) navigable semicircle. When the wind shifts from the northwest to the west, it indicates that the vessel is located in the navigable semicircle of the hurricane. The navigable semicircle is the safer side of the hurricane, where the winds are blowing away from the center of the storm. This allows for better maneuverability and easier navigation compared to the dangerous semicircle, where the winds are blowing towards the center of the storm. The other options are incorrect because a low pressure area (A) is not specific to the location within the hurricane, the eye of the storm (B) is the calm center of the hurricane, and the dangerous semicircle (C) is the more hazardous side of the hurricane, opposite the navigable semicircle.
