What can sailors do to prepare for sudden weather changes?

To prepare for sudden weather changes effectively, sailors should stay updated with real-time weather data. This approach ensures that they have the most current information regarding potential changes in wind patterns, storm activity, and other critical conditions. Given that weather can be unpredictable, relying on outdated forecasts could leave a sailor unprepared for hazardous conditions.

Continuous access to real-time weather reports allows sailors to make informed decisions while at sea, including when to alter their course or adjust their sails to anticipate shifts in wind and weather. This proactive behavior is essential for safety and optimizing sailing performance.

The other choices do not support effective preparation for sudden weather changes. Ignoring small changes in forecasts can lead to risks that arise from underestimating the weather's unpredictability. Only paying attention to weather while in port neglects the dynamic nature of maritime conditions that can shift rapidly when at sea. Lastly, adjusting sails less frequently can be dangerous, as conditions may necessitate frequent adjustments to maintain control and safety.
