The boat has twin, kick-up rud- ders, to avoid damage, two spare blades are carried and there is also a spare set of bearings on the centerline for use with an emer- gency tiller. The requirement for an engine and drive that is easily removable for racing has led to a truly unique solution, a removable, underwater module carrying a 150-hp Cummins diesel and Traktor waterjet. This is backed up by a portable, hydraulically-driven outboard mo- tor, on the same circuit that drives a windlass, a small bowthruster, the water-ballast pumps and the steer- ing system. Hydraulics also drive a pumping system that can move 1,000 gallons of water ballast from one side of the hull to the other. Power is provided by a take-off from the Apollo 6kW diesel genset.

The objective of RULES 2000 is to improve ship safety through the use of advance technology. This is being achieved through the modernization of ABS Rules using state-of-the-art analytical techniques, development of ad- vanced design resources for the marine industry and technical sup- port services for customers. Under RULES 2000, ABS has al- ready produced several particularly noteworthy advancements. One, first offered to the public in 1991, is the Dynamic Loading Ap- proach (DLA), a "design-by-analy- sis" procedure for more accurate modeling of expected ship loads and dynamic stresses than with tradi- tional methods. DLA allows a more rational dis- tributor of material in the hull struc- ture and results in conservatively biased scantlings. The DLA has received widespread acceptance and is being successfully applied in practice. With the project's completion, ABS will have produced new scant- ling requirements for the "Steel Rules" accompanied by the neces- sary computer software.

The vessel will also fea- ture two 16V-149TI DDEC Detroit Dit^el engines and Cincinnati Gear transmissions. The boat is being developed to conform to the chang- ing needs of worldwide navies as they plan for the 21st century. A primary consideration will be the resizing of naval forces and the need to command the seas and en- gage in missions in the complex op- erating environment of the earth's coastal regions. According to W. Dennis Suit, who is president of Atlantic Boat Group, "The advanced craft will have an extensive range and multi-mis- sion capabilities and will be more readily deployable to scenes of ac- tion anywhere in the world." Preliminary design work is being performed by the naval architecture firm Sparkman & Stephens of New York and a prototype is expected to be ready for initial performance and evaluation within 18 months.
