 Finnish-Swedish ice class

The Finnish-Swedish ice class system is a classification system used to define the ice-strengthening requirements of vessels operating in icy waters, mainly in the Baltic Sea and surrounding areas. This system helps ensure that ships can safely navigate through ice-covered waters, which can present significant hazards to navigation. The Finnish-Swedish ice classes categorize vessels based on their design, construction, and capability to move through ice of various thicknesses and densities.
