Marine Semi-Spade Rudder
The upper half of the marine semi-spade rudder is supported on the rudder knob at the rudder post or rudder arm, and the lower half is in a hanging shape.
A semi-spade rudder has its lower part attached to the ship's hull, while the upper part is free, extending down from the stern of the vessel. This configuration resembles a spade, hence the name.
The rudder is typically supported by a rudder stock, which is connected to the steering mechanism. The lower attachment to the hull provides additional support and stability, reducing the stress on the rudder post compared to a full spade rudder, which is completely free-standing. This design reduces the load on the bearings and rudder stock, enhancing durability and reliability.
Overview
The marine semi-spade rudder is mostly used to control the performance of low requirements of the sea ship and as a inland ship side rudder. With the propeller, the semi-suspension rudder is arranged behind the wooden and aft support. It is commonly applied to goods transportation on seas for large ships and vessels.
Marine semi-spade rudders represent a versatile and robust solution for many types of vessels, offering a compromise between the agility of a full spade rudder and the strength of other rudder. Their design optimizes performance and durability, making them a popular choice in both commercial and recreational maritime applications.
