RUDDER ASSEMBLIES AND RUDDER TUBES Rudder Tubes, Bearings and Tiller Arms Clements Engineering manufactures a number of rudder profiles to suit individual hulls, ranging from slow speed displacement boats to ‘deep v’ planing designs and many other applications. The principal designs are show below and include dagger type, conventional spade and wedge profile rudders. Rudder design is of paramount importance to the performance of the boat, especially for high speed craft. Steering performance must be optimised, whilst drag is kept to a minimum. Clements Engineering’s experience help the boat designer optimise conditions both in terms of high speed directional sensitivity and low speed manoeuvrability. Through-hull mounted rudders - generally cast in one piece from either AB2 (nickel aluminium bronze) or HTB1 (high tensile brass) and mounted through the hull in a rudder tube fixed to the inside of the hull. Bearing and sealing arrangements depend on the design selected. Transom mounted rudder assemblies - precision machined from one piece castings in HTB1 or AB2 and are fitted with seals to prevent ingress of water. Backing plates can be supplied with fixing bolts and greasers for lubricating bearings. These can include an integrally cast, anti-cavitation plate at the top of the blade. On request Clements Engineering manufacture bespoke plate rudder profiles from either mild steel, type 316 stainless steel or F51 Duplex. Alternatively, hollow aerofoil type 316 stainless rudder/ stock assemblies are available from inhouse designs or to customers’ drawings. All rudder/ rudder stock assemblies can be supplied to order.

M^^^CLEMENTS MARINE RUDDER TUBES Clement Engineering manufacture various types of rudder tubes ranging from GRP glass in tubes, Bronze tubes and steel fabricated tubes. Polyester resin tubes, turned to exact required diameter. Internal bore and tube ends are gel coated. Bronze tubes are available in HTB1, LG2 and to be either bonded or bolted in. Stainless steel, mild steel and aluminium tubes are available to be welded directly into the boat or chock fasted into a larger diameter tube. All the above tubes come complete with the following options for bearings • Packed gland • Class approved...
