In the Northern Hemisphere, your vessel is believed to be in the direct path of a hurricane, and plenty of sea room is available. Which is the best course of action?
• Dangerous semicircle vs navigable semicircle of a Northern Hemisphere hurricane • Relationship between wind direction, storm center, and your ship’s heading • Effect of placing the wind on different quarters/bows on whether you move toward or away from the eye
• First, picture the hurricane in the Northern Hemisphere: which way does its wind circulate, and how does that affect the side of the storm you’re on? • If you are in the direct path, do you want to move across the storm track into the navigable semicircle, or stay in / move toward the dangerous semicircle? • For each choice, imagine where the storm center would be relative to your ship if you put the wind in that relative position—does that take you away from or toward the storm’s eye and track?
• Verify the direction of wind circulation around a low-pressure system in the Northern Hemisphere • Check which combination (bow vs quarter, port vs starboard) is traditionally taught to keep clear of a hurricane’s path when in its direct track with sea room available • Confirm that the chosen relative wind position would tend to move you out of the storm’s path, not across into the worst semicircle or toward the eye
