ULTRAJET 340HT – Ultra Dynamics Unveils New Waterjet

Press Release
Friday, August 31, 2012

Ultra Dynamics has released a new waterjet model to its HT (High Thrust) range, the UltraJet 340HT.  The new design allows for an engine input power of up to 410 kW (550 bhp).

As with all other HT waterjets in UltraJet’s range the UJ340HT (high thrust) unit was designed to provide excellent high speed and cruising performance - with superior cavitation resistance at low speeds and when under more extreme load, towing, or thrust conditions. The 340HT will be of benefit to boat builders of Seismic, Landing Craft, Cargo carrying, Commercial and Military Tow vessels, where high static thrust is a prerequisite.

The UJ340HT has a similar physical size and weight to the standard UJ340 waterjet, but utilises a different impeller to achieve higher thrust per horsepower compared to the standard UJ340 and other similar-size waterjets on the market.

Following Ultra Dynamics practice, this new model is constructed from marine grade aluminium alloy, with the impeller, impeller ring and shafts made from stainless steel.  The design and materials emphasise high performance, efficiency and durability to permit reduced operating costs for boat owners and operators.

The new model features a compact balanced reverse deflector with superior zero-speed and reverse manoeuvring performance with the intake block positioned further aft against the transom.  The intake housing is designed for good water flow to the impeller at lower boat speeds and for sprint speeds up to approximately 35 knots, depending on hull type.

The UJ340HT can utilise UltraJet’s Hydromechanical (HM), Electrohydraulic Jog (EHJ), Electrohydraulic Proportional (EHK), JetMaster-Pro proportional (JMP) or JetMaster Joystick (JMJ) reverse and steering Control systems.  Standard manual hydraulic steering and optional hydraulically power-assisted steering is available for single and twin installations.

With a similar hull footprint boat builders are able to offer a standard UJ340 for most general applications and the UJ340HT as an option for heavier boats, towing, or high bollard-pull applications.
