Offshore Equipment

A Protecl in almost any kind of water," said Captain Troy

Waters, principal of Effensachs Marine of Holly- wood, "and do, so we needed a tough, seaworthy boat with a group of useful mounts to take move footage on the water." North wind Marine answered this unique casting call with its latest

Extreme Rigid Hull Inflatable (RHIB) is designed to be a rugged, aluminum boat that movie and TV producers can send out to carry a boom-mounted camera and other production gear in the roughest conditions. The 34-ft. (10.3-m) vessel packs a lot of equipment and can provide seating for 26 pas- sengers as a crew or support boat. It sports a pair of 250-hp Yamaha outboard engines to drive the vessel to 45 knots. Capt. Waters operates 19 dif- ferent boats, but contends that his newest vessel is "larger, faster, and more heavily built than our other boats." He is a licensed mariner who worked on commercial vessels before becoming involved with his current business.

Constructed of marine-grade aluminum in accordance with USCG subchapter T require- ments, the boat received an extra strong deck on which to attach heavy equipment. The boat also carries special "speed rail" fittings for mounting a variety of production equipment. The boat is com- pleted with a 3.5 kW Kubota generator, Standard

Eclipse VHF radio and a Raytheon Pathfinder

GPS/Radar/Chartplotter. Northwind Marine builds a range of Extreme RHIBs from 17 to 50 ft.

The RHIBs use poly urethane sponsons from Wing

Inflatables of Areata, Calif.

Smoothing Out the Waves

As RIBs are being used in increasingly rough waters further from shore, quality and stability of ride have become even more critical factors in selecting the appropriate solution. Ocean Techni- cal Services Inc. (Otech) is a full-service ship- yard and RHIB manufacturer located in the New

Orleans metro area. The company's Ocean Sprint

RHIB's unique hull is designed for exceptional performance, as the deep-vee hull flattens to a delta conic planning curve at the transom and con-

Dr 28. tains a series of concave spray chines that run the full length of the boat. Taken together, it is designed to provide a dry ride with exceptional handling in rough waters. The design was actual- ly originated by Crompton Marine Ltd., who offered the design after 18 years of experience with RHIBs in the hostile North Sea conditions.

Licensed by Crompton, Otech has modified the series to incorporate a molded deck and quick tube replacement system. The inflatable collars are manufactured for Otech by Henshaw Inflata- bles. The company's 23 ft. (7 m) RHIB can accommodate power up to 300 hp, carrying up to 20 crew and passengers, or a maximum load of 3,890 lbs. It features a fire retardant fiberglass hull and deck, and a quick change attachment system for easy tube replacement. The 7 m units, after considerable modification, were recently put on sea trials by the U.S. Navy, which will be pur- chasing an undisclosed number of boats for ship- board use.

The Revenger line of RIBS is also geared to han- dle the roughest of conditions in the smoothest of manners, based on a proven raceboat design. The deep-vee hull together with three wide spray rails is designed to offer superb tight handling, smooth rides and impressive speeds. All Revenger RIBS offer a solid manufacture, complete with longitu- dinal stiffeners, encapsulated in GRP running the full length of the vessel and supporting the bottom spray rails. In addition, a substantial transverse frame (also encapsulated in GRP) supports the hull's longitudinals, and an isophtalmic gel coat surface provides excellent resistance to osmosis.

Revenger currently offers four models, the 23, 25, 29 and 34.

Willard Marine, Inc. offers a full line of com- mercial Rigid Inflatable Boats (RIBs); SOLAS (Safety of Life at Sea) approved and offered through GSA (General Services Administration).

SEA FORCE RIBs are designed to act as a Fast

Reaction Rescue and Boarding Boat that may be (Continued on page 52)
