What might a vessel's design include to enhance stability?

A vessel's design to enhance stability often includes features like a deeper keel and an optimized hull shape. A deeper keel increases the vertical center of gravity and provides greater resistance to heeling, which can stabilize the vessel in rough seas. Additionally, an optimized hull shape can reduce drag and improve the vessel’s handling characteristics, which contributes to better overall stability by allowing the vessel to maintain an upright position more effectively.

In contrast, increased decorative features or wider decks do not directly contribute to the vessel's stability. While wider decks can provide more surface area and potentially affect weight distribution, they do not inherently enhance stability in the same way that the keel and hull shape do. Fewer safety regulations also do not enhance stability and can lead to safety risks without improving a vessel's structural integrity or stability.
