Reduces cavitation risk

The classic or conventional rudder series, with no rudder angle limitation and optimised profile designs, provides an economical way of improving the manoeuvring capabilities of most vessels. This range of rudders is built as full spade rudders, with three different standard profiles and no rudder angle limitation, to ensure optimal manoeuvrability for passenger, cargo vessels and high-speed craft.

The medium and slim profiles can be combined with a twisted leading-edge for improved efficiency and reduced cavitation risk. Furthermore, with few moving parts it is also easy to install and maintain. This ensures your vessel will have optimal reliability, excellent manoeuvrability and low life cycle costs. For transit speeds the directional stability of the vessel must be considered, we have developed and use advanced computer programs to simulate different manoeuvres such as the IMO criteria (zig-zag test), making it possible to evaluate different rudder sizes and types in order to optimise the rudder design for each vessel.

Type CB - for lower speeds

A bulbous profile and large vane end plates improve low speed manoeuvrability. It shares the same profile as the FB flap rudder and is typically used for offshore supply, cargo, fishing and seismic vessels.

Options

• Heel connection module
• Wire Guard

Type CM - for medium speeds

The profile is optimised to provide good manoeuvrability with propulsive efficiency, with a tapered or rectangular blade, meeting the rudder needs of passenger and cargo vessels.

Options

• Twisted leading edge
• Wire Guard

Type CS - for higher speeds

The slim profile increases overall propulsive efficiency and reduces cavitation risk. The blade is tapered with rounded corners. It has the same profile as the FS flap rudder.

Options

• Twisted leading edge
• Wire Guard
