Maximum manoeuvring performance

A Flap rudder produces more side force than a classic rudder of equivalent size. Depending on shipowner requirements, a flap rudder may be used to reduce the overall area of a rudder whilst maintaining equal lift forces or may be used whenever there is a requirement for high manoeuvrability. Therefore a good understanding of Shipowner requirements is vital when designing a rudder. The rudders can also be optimised for higher speeds and the leading edge of the rudder can be twisted to improve the efficiency and cavitation characteristics of the rudder.

Type FB

The FB type is designed for low to medium speeds.

This rudder has a bulbous profile for maximum manoeuvring performance. The design also has large upper and lower vane plates. It is ideal for use on workboats, fishing vessels, offshore vessels, small tankers, cargo vessels, ferries and other coastal vessels.

Options

• Heel connection module
• Wire Guard

Type FM

The FM type is designed for medium speeds.

Designed with a moderate profile for enhanced manoeuvrability and propulsive efficiency.

Options

• Twisted leading edge
• Wire Guard

Type FS

The FS type is designed for medium to high speeds.

A slim profile that is purpose-designed to suit the vessel. The rudder is built around a cast cone module and has a robust link mechanism and hinge system to withstand the high forces. It is also an ideal all-round flap rudder suitable for a wide range of vessel types.
