Which condition may increase the risk of capsizing a vessel?

High winds significantly increase the risk of capsizing a vessel due to their ability to create large waves, affect the stability of the boat, and challenge the operator's control. When a vessel is in windy conditions, the force exerted by the wind on the sails or the hull can cause it to heel excessively or roll, making it unstable. This is especially true for smaller boats, which are often more susceptible to wind effects compared to larger vessels.

In contrast, low tides, warm temperatures, and calm water do not pose similar risks for capsizing. Low tides may affect navigation but primarily impact water depth rather than stability. Warm temperatures, while potentially influencing the comfort of passengers, do not inherently affect the vessel's balance. Calm water presents a stable environment for boating, reducing the likelihood of capsizing significantly.
