You can determine if your vessel's position is in the dangerous or navigable semicircle of a hurricane by __________.

Correct Answer: Option C — Both A and B

Determining the semicircle requires tracking the storm's path and observing local wind shifts. Plotting successive positions reveals the storm's track relative to your vessel. Simultaneously, observing whether the wind veers (clockwise) or backs (counter-clockwise) confirms your position within the dangerous or navigable semicircle, as detailed in standard maritime meteorology texts.
