Which stability criterion is necessary for cargo ships when subject to steady wind?

The necessary stability criterion for cargo ships when subject to steady wind involves ensuring that the ship does not exceed a heel angle of 16 degrees. This criterion is based on the principles established for the stability of vessels under various conditions, including wind forces.

When a ship encounters wind, it can heel, or tilt, to one side. The 16-degree limit is significant because it represents a threshold for stability; beyond this angle, a ship may begin to experience critical loss of stability. If a vessel heels more than this angle, it risks capsizing or experiencing difficulties in recovery if the wind or sea conditions change.

Maintaining compliance with this 16-degree heel limit ensures that the ship's center of gravity and buoyancy allow for safe operations under wind pressure, fostering safe navigation even in challenging conditions. Adhering to this criterion is an essential part of maritime safety regulations and helps protect both the vessel and its cargo.
