“GO TANGO” & “GONE BANANAS” Single UltraJet 305 waterjets were upgraded to GO TANGO & GONE BANANAS, two rejetted 9 meter (30') thrill ride/excursion vessels. Built by Llandudno Boat Company, using a Revenger GRP hull design, the vessels provide tourist rides from the North Shore of Llandudno, Wales. Power is provided by a 272 kW (370hp) Iveco N60 370 diesel engine. The UJ305 reversing deflector is actuated by Ultra Dynamics' hydro-mechanical control system to provide responsive maneuvers. The thrust provided by the UltraJet permits the craft to accelerate quickly, get onto plane and be ready for the next maneuver. Speeds of 38 knots with full passenger load were reported. Boat owner David Storer stated “The UltraJet 305 paired with the 272 kW Iveco engine is just amazing, we originally had a Castoldi on one of the craft and a Saro surface drive fitted on the other, which simply couldn’t easily get on plane with a full passenger load and only achieved some 28 knots!” Click here to request a PDF with more information.

“CODZILLA” Two UltraJet 575 waterjets propel CODZILLA, a 21.3 meter (70') aluminum excursion vessel designed and manufactured by Ocean Rockets for tour operator Boston Harbor Cruises. The vessel provides tourist thrill rides from Boston’s historic waterfront. Two 1050 kW (1408 bhp) MTU 16VM70 diesel engines power this vessel via ZF550 transmissions. The UJ575 reversing deflectors are independently actuated by Ultra Dynamics' two-lever electrohydraulic control system to provide responsive maneuvers. The thrust provided by the twin UJ575 permits CODZILLA to accelerate quickly and be ready for the next maneuver. Speeds of 37 knots (42.5) mph with simulated full passenger load recorded during sea trials. MP7921

WORLD RECORD BOAT FREE FALL Norwegian boat builder Norsafe recently tested their GES 50 lifeboat by dropping the boat 52 meters (170 ft) from a crane. The realistic test included 90 simulated passengers of 90 kg each strapped into their seats. These lifeboats are used for evacuating crew from offshore oil rigs. While not the first time Norsafe have “dropped” their boats, this was the first to be equipped with UltraJet propulsion and for no damage to the hull and propulsion system. Survival includes being able to move away from the rig under own power. Click here for a video clip of this boat (1.2MB).

OCEAN RANGER EXCURSION RIB A single UltraJet 340 propels this aluminum 10.75 meter (35.3') excursion RIB designed by Global Marine Design of Henderson, WA Australia and built for Thousand Island Expeditions of Pembrokeshire, UK. The vessel carries up to 23 passengers on exciting trips in the turbulent white-water of Ramsey Sound. Power is provided by a single Volvo Penta D9 with 368 kW (493 bhp) at 2600 rpm via a Twin Disc MG5075 transmission providing boat speeds to 38 knots. Excellent low speed maneuvering and overall boat control is with the UltraJet joystick control system. Click here to request a PDF with more information.

50' THRILL EXCURSION JET-BOAT Two UltraJet 376 waterjets propel the HONOLULU SCREAMER, a 15.6 meter (51') aluminum passenger vessel designed and built by Ocean Rockets of Tuckahoe, NJ for the tour operator Honolulu Screamer LLC. The vessel is involved in tourist thrill rides in Honolulu, Hawaii. Power is provided by a two 705 bhp Caterpillar C12 diesel engines via ZF325 transmissions. The UJ376 reversing deflectors are independently actuated by Ultra Dynamics' two-lever electrohydraulic control system to provide responsive maneuvers. The thrust provided by the twin UJ376 permits the SCREAMER to accelerate quickly to be ready for the next maneuver. MP7853. Click here for a video clip of this boat.

ULTRAJET PROPULSION FOR PASSENGER VESSEL This 12.2 X 4 meter (40' x 13.2') passenger vessel built by Kloster Boats of Halsnoy, Norway is propelled a single UltraJet 376 waterjet. Power is from a single 500 hp Iveco C78 diesel engine via a ZF305 transmission. The owner/operator will use as a charter passenger vessel. The same configuration can also used as a crewboat, for nature excursions, and for water taxi duties. Ultra's electrohydraulic (EH) control system is used for proportional operation of the reversing deflector (bucket). ME6447 Click here to request a PDF with more information.

WHALE-WATCH EXCURSION BOAT A twin UltraJet 376 propulsion system propels this excursion boat built by RTM of Montreal, PQ Canada for Jamie's Whaling Station of Tofino, BC Canada. Power is provided by two 435 bhp Yanmar 6CXM-GTE engines via ZF301C transmissions with engine to jet speed ratio of 1.408:1. Independent operation of the reversing deflectors is with Ultra's electrohydraulic (EH) control system. Speed of 36 knots reported during initial sea trials.

BLUE HERON EXCURSION RIB A single UltraJet 376 propels this aluminum 11.5 meter (37.5') excursion RIB built by Hike Metal of Wheatley, ON Canada, designed by E.Y.E Marine Consultants of Dartmouth, NS, and operated by The Blue Heron Company of Tobermory, ON. The vessel carries passengers between Tobermory and Flower Pot Island in Georgian Bay. Power is provided by a single Caterpillar C12 with 700 bhp at 2300 rpm with direct drive to the jet.

BOAT BUILDER IMPRESSED WITH ULTRAJET PROPULSION Twin UltraJet 305 waterjets propel the Spirit of Skye, a 48' (14.75 m) 36 passenger ferry now operating a scheduled 26 nm service between Portree and Gairloch in the Isle of Skye. Designed by Ace Marine and built by Sandy Morrison Engineering, the Spirit is powered by two 315 bhp Cummins 6BTA5.9M diesel engines. Sandy Morrison reported "the Spirit of Skye finished its trials with flying colors. The performance was better than hoped for by a large margin. A top speed of 32.7 knots was recorded. The vessel is now in service - the jets are superb and well ahead of other types we have used." Click here to request a PDF with more information.

OWNER WISHES HE HAD CONVERTED TO ULTRAJET SOONER! Twin UltraJet 340 waterjets replace the jets originally installed by the boat builder, RTM of Quebec, Canada. Dixon Industries of Richmond, British Columbia performed the conversion to UltraJet propulsion. Power to the UltraJet units is from two Caterpillar 3126 diesel engines. The UltraJet impellers selected for 380 bhp @ 2500 rpm to achieve optimum cruise performance with full passenger load. Vessel owner, Cedric Towers of Vancouver Whale Watch said, "The Explorathor is just like a brand new boat. It has never gone as fast and been so manageable. I only wish I had re-jetted sooner."

LUXURIOUS RIVER & BAY CRUISING Twin UltraJet 305 waterjets propel this 18 meter (59') cruise/dinner boat built by Artisans at Ynyslas, Wales. Power to the UltraJet units is from two 180 hp Cummins 6BT5.9M "low emission" engines, via ZF gearboxes. The steel catamaran will carry up to 50 passengers and a crew of 10. 'Seren-Y-Bae' passengers will cruise in low vibration, temperature-controlled, luxurious surroundings with dancing and entertainment as they enjoy the changing scenery of Cardiff Bay. The catamaran's design was dictated by low bridges and very shallow water in the upper reaches of the cruising range. At 36 tonnes she draws just under 46cm (18"). A low-wake hull ensures no disturbance to other craft or damage to riverbanks. Click here to request a PDF with more information.

DRIVEN WITH ONLY A JOYSTICK A single UltraJet 305 propels this 10.75 meter (35') excursion RIB built by Ali-It Marine of Pembrokeshire, England and operated by Coastal & Island Cruises. The vessel carries 23 passengers plus 2 crew on wildlife tours between Tenby, Caldy, and St. Margaret's Island. Power is provided by a single Yanmar 6LYA-STP, 370 metric hp at 3300 rpm via a ZF220 transmission with 1.237:1 ratio. A top speed of 35 knots with 30-32 knots the normal operating speed on tours. Unique is the joystick-only control of the jet drive and bowthruster - there is no wheel. Steve Crockford of Coastal & Island Tours stated "The joystick gave plenty of response - from the mid range right through to the top end of the power band, shifting all six tons of RIB with ease."
