High block coefficient vessel
Web25 de fev. de 2024 · The coefficient lies between 0 and 1 where 1 resembles the shape of a perfect block. Thus, ships such as tankers and bulk carriers that have fuller hull forms have higher block coefficients. On the other hand, ships such as yachts and container vessels with finer forms have lower block coefficients. Webdirectional stability of ships. However, most ships with high block coefficient are inherently dynamically unstable. Ships having moderate or small amount of directional instability could be handled quite safely, but ships having large amount of directional instability are difficult to handle and may pose danger to sea traffic.
