Fishtail Rudder

Application

The fishtail rudder is characterized by a curved and tapered shape that resembles the tail of a fish. The tapered shape reduces drag and turbulence as the water flows around it, while the curved shape improves the distribution of hydrodynamic forces and improves steering control. The fishtail rudder is designed to provide precise and responsive steering control, even in rough seas or high-speed conditions. It is often used in combination with other hydrodynamic features, such as a bulbous bow or a stern wedge, to further improve the vessel's efficiency and performance.The fishtail rudder has a simple structure and can be installed on the stern of the ship singly or in pairs, which can significantly improve the course keeping and maneuverability of the ship. The maximum rudder angle can reach 70 degrees. In this case, the rudder force provided by the fishtail rudder at the stern can achieve a good side thrust effect.

Advantages and Features

1.High lift coefficient, reduced turning diameter of vessel.

2.Increased steering quality of vessel.

3.Improve the steering response and turning performance of the ship.

4.Reduced rush-forward distance when braking.

5.Reduction of steering times during the sailing.

6.Extended navigable zone and increased economic benefit of vessel.

7.Rotation axis bush of non-metal material with water lubrication, no pollution.
