What protects boats from sea waves?

Boats are protected from sea waves primarily through their hull design, which often features a streamlined shape to minimize resistance and improve stability. Additionally, boats may be equipped with stabilizers or keels that help maintain balance and reduce rolling in rough waters. In harbors, breakwaters and docks provide further protection by absorbing wave energy and creating calmer conditions for moored vessels. Lastly, the choice of materials and construction techniques also contribute to a boat's resilience against wave impact.
