1980s and studied the engineering of the system and the economics of doing it."

He further explained that while no shipbuilding interest has taken advantage of this technology, the

NNS study proved that it is an effi- cient and economically prudent investment, in which the larger upfront capital costs of installing technology can be offset by savings in other areas in the long run. Dr.

Peters also stated that the copper industry has demonstrated that use of this technology on large, oceangoing ships does not lead to rapid galvanic corrosion of ships' hulls.

While the maritime industry is not reknown for breaking with con- ventional methods of getting things done, many are hopeful that industry personnel will embrace the use of advanced construction materials such as copper. The challenge to this process lies in convincing people to sacrifice upfront costs for the technological and economical payoffs that will surely follow. In the meantime, several organizations are continu- ing to test advanced materials for marine applications in order to uncover operational advantages of new technology. One such organi- zation is LaQue Corrosion Services in Wrightsville Beach, N.C., where an ongoing testing program on the use of copper in sheathed hulls and marine pilings is striving to perfect the next-generation innovations that will lead the industry into the 21st century. CDA has also report- edly carried on a program with oil companies over the past several years in order to perfect the use of copper as an offshore sheathing technology.

Small Cruise Ship Gets $4.1 M Upgrade

The 215 x 37 x 8.5-ft. (65.5 x 10.6 x 2.5-m), 107-passenger Spirit of

Endeavour, the new flagship of

Alaska Sightseeing/Cruise West (AS/CW), underwent $4.1 million in renovations before sailing on its first series of cruises in November 1996. Built in 1983 at Jeffboat for

Clipper Cruise Lines, Spirit of

Endeavour, ex-Newport Clipper, was purchased by AS/CW in 1995.

New design and shipyard work was performed by Pacific

Fisherman Inc. and Elliott Bay

Design Group of Seattle, and by

B.C. Research, Inc. and Nautican of Vancouver.

Shipyard refit work included installation of new bow and stern designs that are expected to increase the vessel's fuel efficiency by approximately 22 percent. A new bulb-like configuration forces the current up and away from the hull, thereby reducing the bow wake and water resistance. A new stern ferring forces water to flow closer to the surface, creating a gently rolling wave that reduces the amount of drag created by the original stern. Bryce Brockway,
