In the Northern hemisphere which semicircle of a hurricane is the navigable semicircle?

Official USCG Answer & Rule Citation

Correct Answer: Option C — Left

As detailed in Bowditch's marine meteorology chapters, the left semicircle of a Northern Hemisphere hurricane is termed the navigable semicircle. Winds in this region tend to blow a vessel away from the storm track and generally experience lower wind velocities.
