monohullaisia

Monohullisia is a Finnish term referring to monohull vessels. A monohull is a boat or ship with a single hull. This is in contrast to multihull vessels, which have more than one hull. Monohulls are the most common type of watercraft and have been used for centuries in a wide variety of applications, from small fishing boats to large cargo ships and passenger liners.

The design of a monohull typically focuses on stability derived from the hull's shape and ballast. The hull's shape can be designed to be wide and flat for greater initial stability or narrow and deep for better performance and seakindliness. Ballast, often in the form of heavy material placed low in the hull, provides the righting moment to return the vessel to an upright position when heeled by wind or waves.

Advantages of monohulls include their generally simpler construction and lower cost compared to multihulls. They often exhibit better performance in heavy seas, as the single, deep hull can cut through waves more effectively. However, monohulls can have a tendency to roll more than multihulls, especially when at anchor or in beam seas. Their interior space is also typically less expansive and more compartmentalized than that of a comparable-sized multihull. Despite these characteristics, the monohull remains the dominant design in maritime transport and recreational boating worldwide.
