"NO WORRIES" WITH ULTRAJET PROPULSION This 53' (16.1m) aluminum catamaran named "NO WORRIES" is propelled by twin UltraJet 340 drives. Power is supplied by 493 bhp (368 kW) Cummins QSC8.3 diesel engines via 1:1 ZF transmissions. Vessel control is with Ultra's joystick control at the helm (no wheel) and a remote joystick station on the aft deck. The system also features Ultra's unique electronic steering synchronization as a mechanical tie-bar was not practicable. The private owner will use their new catamaran to cruise home port of Tampa Bay, the coast of South Florida, and surrounding islands.

NEW, FAST, STYLISH "PT COMMANDER" Twin UltraJet 305 waterjets propel the new 39' (12 m) PT Commander designed and manufactured by Rivolta Marine of Sarasota, Florida. Power is delivered by twin Yanmar 6LY2M-STE diesel engines, via ZF220 transmissions. Rivolta reported the PT achieved 37.1 knots during sea trials. Control of the jets is with Ultra's joystick control system with integrated control of the hydraulic bow thruster (also supplied by Ultra Dynamics). Several modes permit operation on joystick alone for maneuvering around the marina, joystick steer for transit, and conventional operation by wheel and throttles for cruising. The PT Commander uses the same hull as the Rivolta Jet Couple which is also propelled by a twin UltraJet 305 propulsion system.

FAST 29' EXPRESS CRUISER A single UltraJet 305 waterjet propels the "Carapace," the first jet-propelled version of the popular Surfhunter 29 designed by C. Raymond Hunt Associates and manufactured by Hunt Boatbuilders, Inc. of South Dartmouth, MA. Power is delivered by single Yanmar 440 mhp 6LY2A-STP diesel engine, via a ZF220 transmission.

The shallow draft permits the owner to keep the boat at his residence despite minimum water at low tide.

OUTPERFORMS EARLIER MODELS Rivolta Marine recently launched their Coupe J-4 upgraded to UltraJet propulsion. This twin UltraJet 305 version of the Coupe J-4 has faster acceleration and higher speed than the previous models with the same engines. Power is provided by a twin 370 hp Yanmar diesel engines via ZF220 transmissions. 440 hp engines are optional. Operation of the twin UltraJet steering and reversing is with the UltraJet joystick control system. The hydraulic bow thruster, powered by an Ultra Dynamics' hydraulic system, can operate for extended periods and, in coordination with the jet drive, provides the ultimate in maneuverability.

BUILDER IMPRESSED WITH ULTRAJETS Twin UltraJet 340 jet drives propel this new 33' aluminum catamaran designed and manufactured by Maxweld Boats, Inc. of Hebo, OR. The private owners plan to use "JUST BECAUSE" for cruising in British Columbia and Southern Alaska and for fishing trips off the central California coast. Power is provided by twin 450 bhp Caterpillar 3126 diesel engines via ZF280 transmissions. Boat speed is in excess of 30 knots at full displacement including 470 US gallons of diesel fuel. The reversing deflector on each UltraJet drive is operated with the new Ultra/Glendinning electrohydraulic control system. Click here for more information on this control system. The builder remarked that he was impressed with the way this boat accelerated "out of the hole". Better than previous jet boats he had built.

BUILDER SAYS "PRETTY AMAZING" A single UltraJet 305 now propels “Mystic” a 29’ sports fishing/excursion boat built by Costa Azul of Cost Rica. Power is provided by a single Caterpillar 3116 rated at 350 bhp. A marine transmission is not installed. Prior to replacing the original jet drive, the builder reported difficulty getting the boat on plan, limited boat speeds and inability to plane with normal passenger load. With the UltraJet 305 drive, he reported much improved acceleration and a boat speed of 35 knots with a displacement of over 5 tons plus the ability to plane with a full passenger load. The reversing deflector is operated with Ultra’s Hydromechanical control system. To quote the builder, Mike Anderson, “this week the boat hit 35 knots, remember that's a single jet with a 350 Cat, so pretty amazing.”
