Outline of VL-Vec Twin System Improvement in rudder performance has come to be an important element for very large blocky ships such as VLCCs, in which importance is attached to maneuverability. It can be considered to increase rudder area in order to cope with this question, but in case of a single rudder arrangement, an […]
An Increasing Demand for Fish Tail Rudders A Fish Tail Rudder is a rudder in special shape, having sectional profile of fish-tail-like trailing edge. This rudder remarkably improves ship’s maneuverability and course keeping quality without any propulsive loss, and significantly contributes to safety and economy of ships. Fish Tail Rudders have established high appraisal in […]
Fish Tail Rudder For Ship CONCEPTION Fish Tail Rudder is a rudder designed under such conception as to effectively utilize the propellers slip stream for rudder action, and featured by having a fish-shaped horizontal cross section, top and bottom end plates, and optimized rudder height and chord length, and being so arranged that the rudder […]
Ocean Fish Tail Rudder “Fish Tail Rudders” which have been giving many excellent results up to now are categorized as a high lift special rudder, and mainly aimed at excellent maneuverability in port in such a manner that a forwarding component of a ship’s propulsive force can be reduced to zero when most suitably designed, […]
Thordon Rudder Bearings Function Thordon Rudder Bearings are made of homogeneous, elastic bearing material that is composite of rubber and resin.
