ROV –SUPPORT VESSEL A single UltraJet 305HT propels ‘Lisa Marie’ a new 11m (36’) aluminium ROV-Support vessel designed and built by Kåre Holthe & Sønner AS, Norway. Powered by a single Volvo Penta D6-370 engine coupled to a single UltraJet 305HT waterjet via a ZF gearbox to return speeds of 29 knots with a weight of approximately 5 tonne. Ultra’s hydromechanical (HM) control with a single helm lever operates the reverse deflector. A bow thruster is powered from the PTO on the gearbox. An electric powered winch capable of lifting 500 kg deploys a remote-operated vehicle for fish farming survey work. The result of which is time and cost savings for the owner’s aquaculture clients.

Mare Safety AS Delivers New Rescue Craft Twin UltraJet 410 waterjets propel the MARE MSDC, a new 12.4 meter (41’) aluminum rescue craft built by StatoilHydro of Norway. She is assigned to the ‘Stril Hercules’ a new 55.2 meter Area Standby Vessel operating in the Tampen oilfields of the North Sea. The craft is capable of high speeds and yet have a high bollard pull for towing lifeboats in addition to general operations from its mother vessel. Powered by twin Volvo Penta D6-435 diesel engines rated at 320 kW @ 3500 rpm, MSDC 12 achieved a top speed of 36 knots and a 32 knot loaded cruising speed. The test program which took place in Ulsteinvik covered self-righting and self bailing, jet and engine performance, shaft torque, power and thrust, during which the twin UltraJet 410s achieved a bollard pull of 4.0 tonnes (8,816 lbf).

The reverse deflector is operated with Ultra’s hydromechanical (HM) control system. Owner Thea Thomas operates Myrmidon in Alaska's Copper River Fishery, stated “I am absolutely thrilled with my new boat, the more I run it the more I like it. After 20 years of having outdrives, the ease and stress free operation of a jet is amazing. Everything is easier with the jet, especially maneuvering the boat while around the net. The UltraJet 305 paired with the Cat C7 seems to be an excellent combination." MP7887

ULTRAJET 305 FOR 31' BOWPICKER A single UltraJet 305 propels this aluminum bowpicker operating in Cordova, Alaska. Owner Jeff Phillips replaced the originally installed jet with the UltraJet matched to the existing Volvo 63L engine. Jeff states, "I am ... able to run 100-200 rpm's lower with the Ultra Jet than I did with the Hamilton (jet), and my speed is better than before, even at those lower rpm's. It will definitely push more weight, although I haven't determined what it won't push. I have been able to plane with 800-1000 pounds of fish onboard in the ocean... . With the Hamilton, I virtually was done planing with half of that weight." MP7932

TWIN UJ305 PROPEL NEW OILFIELD SERVICE BOATS Twin UltraJet 305 waterjets propel the first of series of 7.2 meter (23.5’) aluminum oilfield service boats designed and built by Aluminum Chambered Boats of Bellingham, WA for an international oil company.

NEW WORKBOAT ACHIEVES NEAR 40 KNOTS This 45' workboat is propelled by twin UltraJet 340 units each powered by a 430 hp Cummins 6CTA8.3M diesel engine via ZF305 transmission. Other than that, we let the boat owner/operator speak for the UltraJet units: "We were very impressed by the performance of our new boat; it's very responsive and jumps onto plane in no time. The maneuverability that the jets provide us with is exceptional and the load carrying capabilities and speeds we are achieving are also impressive. With one quarter of fuel and a crew of two we are getting close to 40 knots top speed! This is better than we had ever hoped for. On one occasion we added an extra 8 tons of load to the boat and were still able to get 28 knots! That was really impressive! In another we towed a boat that weighed 100 tons at a speed of 12 knots."
