Thrusters, Water Jets, Propellers & Gears (Continued, from page 31) series models, for vessels of all dif- ferent hull structures and sizes. The HJ series is a range of high effi- ciency, single-stage axial flow units. Offering a large number of models and impeller rating combinations allows these jets to be directly driven by all common gasoline and marine diesel engines up to 1,200 kW in high speed craft, eliminating the need of a gearbox. The HS series is a range optimized specifically for very high speed craft operating in the 45- to 60-knot speed range. The series features a multi-stage axial flow pump design. The HM series is an extension to the HJ series, is suitable for power inputs up to 3,000- kW, and designed for the propul- sion of fast ferries, workboats and patrol boats in the 66- to 164-foot range.

The wraparound inflatable collar is both a stabilizer that assures smoother handling in even the roughest seas, and a fender that cushions against hull damage during boarding operations. ZODIAC Hurricane's computer designed, commercial grade hull is reinforced in all the right places. Its computer designed lifting stakes generate high lift at low speed. This deep "V" design provides excellent high speed maneuverability and unsurpassed sea- keeping ability, all the reasons why ZODIAC Hurricane is the choice of professional users worldwide. ZODIAC OF NORTH AMERICA, INC. P.O. Box 400, Thompson Creek Road Stevensville. MD 21666 (410) 643-4141-ext. 3009 supplier for the Finnyards-built Ice- breaker Fennica, a vessel honored as an Outstanding Oceangoing Ves- sel of 1993 by Maritime Reporter & Engineering News (December, 1993). The company focuses on con- trollable and fixed-pitch bow and stern thrusters, azimuthing thrust- ers, complete drive system packages (both diesel electric and hydraulic) and related control systems. Also featured on the Fennica were Aquamaster-Rauma propul- sion units. Known worldwide for its Z-drive and winch systems, Aquamaster-Rauma recently formed a new company on the Gulf Coast to exclusively handle the marketing and distribution of its Aquamaster propulsion and Rauma deck equip- 32 Circle 258 on Reader Service Card Shipwrights recently introduced a new Twin Prop bow thruster system. ment in the U.S. Headquartered in Metairie, La., Aquamaster-Rauma will be responsible for the distribu- tion of Z-drives, ice-strengthened Z- drives and contra-rotating propeller drives. In addition, the Louisiana-based company will offer Aquamaster- Rauma's experience in vessel design concepts which optimize the propul- sion system. Within the last year in the U.S., Aquamaster-Rauma has sold Z-drive systems for a multipur- pose tug under construction at Nash- ville Bridge and the $60-million over- night passenger ship American Queen being built at McDermott Shipyard. The Nashville Bridge project, the twin screw 6,000-hp tug Kinsman Hawk, will be the most powerful Aquamaster tug delivered to date. Shipwrights Inc. recently un- veiled a new Twin Prop bow thruster, a system the manufacturer claims can exceed the effective use of 10-hp in an eight-inch tunnel, and in fact effectively use up to 50-hp in an eight-inch tunnel. Shipwrights claims that since the system is only about one-fourth the size of that required by systems of comparable power, the openings can be located lower and further for- ward in most hulls, resulting in greater leverage, while maintaining hull integrity and hydrodynamic ef- ficiency. The tunnels are constructed of GRP composite, aluminum or steel. Maritime Reporter/Engineering News
