PROPULSION UPDATE

Cummins Diesels Selected To

Repower Research Vessel Calypso

The well-known Cousteau Society oceanographic research vessel Ca- lypso recently underwent a major refurbishing at the Merrill Stevens

Dry Dock Company in Miami, Fla.

The vessel's engineers and mechan- ics installed two Cummins KTA19-

M diesels, along with Twin Disc reduction gears, and new shafts, gensets, and electrical systems in preparation for a five-year journey to film a new series entitled "Redis- covery of the World."

Furnished by Cummins Metro- power of the Bronx, N.Y., the

KTA19-Ms were selected to replace the vessel's original 1942 vintage twin diesels rated 500 bhp each, which were deemed too old to com- plete the five-year trip. The Cum- mins KTA19-M is a six-cylinder, in- line, four-cycle turbocharged and aftercooled diesel rated 500 bhp at 1,800 rpm. The new engines are expected to reduce the Calypso's fuel consumption nearly 50 percent and increase cruising speed by as much as two knots. Operating at a derated 1,200 rpm, the KTA19-Ms will consume approximately 7.3 gal- lons per hour, significantly less than the 14.5 gph required by the old engines.

Built by Ballard Marine Railway

Yards in Seattle, the Calypso was originally designated J-826, a YMS

Class minesweeper. The 141-foot ship was commissioned into British service in March 1942 as a lend- t'utuinut 100% OIL

Mediterranean. She was transferred back to the U.S. Navy in 1947, and in 1949 was sold and converted into a ferryboat that ran between Malta and Gozo Island. It was then that she acquired the name Calypso. In 1950 she was sold to Jacques

Cousteau, then a young French

Navy lieutenant commander, and was soon transformed into an ocean- graphic research vessel.

Nichols Brothers Boat Builders,

Inc. on Whidbey Island (Freeland),

Wash., recently delivered the luxury cruise vessel Executive Explorer, a catamaran designed to carry 49 pas- sengers, to Glacier Bay Yacht

Tours, Inc. of Seattle. The 104-foot, four-deck vessel has a beam of 36 feet 9 inches and full-load draft of 8 feet 3 inches.

Propulsion is provided by two

Deutz 816 diesel engines, each with an output of 1,346 bhp, driving five- bladed Nicel propellers manufac- tured by Columbian Bronze, via

Reintjes WVM 842 2.96:1 reduction gears supplied by Karl Senner, Inc. of New Orleans. Top speed for the loaded vessel is 22 knots. She is steered by conventional rudders employing a Wagner steering sys- tem supplied by Hough Marine of

Seattle. The 5-inch Aquamet 17 shafting was supplied by Coolidge

Propeller of Seattle, and propulsion controls are from Systems Engi- neering. Harco of Portland supplied the silencers.

The vessel has accommodations for a crew of 20 in two bunkrooms in the hulls and several upper cabins.

The 25 passenger staterooms are all located on the outside periphery of the Bridge, Upper, and Main Decks.

All cabins feature color television,

VCR units, mini-bar/refrigerators, and wide windows. Other facilities on the Main Deck include the Vista

View Lounge forward, the Explorer

Dining Room, and the galley. The topmost Observation Deck is an open solarium.

According to Nichols Brothers president Matt Nichols, the Exec- utive Explorer is the first U.S.-flag catamaran cruise vessel of its type built in the U.S. She is the sixth of a series of catamaran vessels built at the Whidbey Island yard to designs by International Catamarans of

Australia. Two additional catama- rans are currently under construc- tion at the Nichols yard—a 300-pas- senger excursion day boat and an 86-foot commuter vessel for use in

San Francisco Bay by the Red &

White Fleet.

Electrical power is supplied by two 120-kw Mercedes-Benz diesel generators supplied by Pacific Die- sel of Seattle. A sewage treatment plant supplied by Sea-Land Indus- tries of Tacoma is based on Orca II equipment from Envirovac. Peter

Kalby Company of Bellevue engi- neered and supervised installation of an extensive heating, air condi- tioning, and ventilations system; one of its functions provides indi- vidual HVAC to each stateroom.

Northern Marine Electronics of

Seattle supervised installation of the electronics suite, which in- cludes: Furuno FCR 1411/G and F 803D radars, LC 90 Loran C, FSN- 90 SatNav, and 108 Weather-Fax;

ICCM M-700 SSB and ICM-80C

VHF radiotelephones; Ross depth finder; Simrad watch receiver; and

Aiphone TB-12F intercom stations.

The Executive Explorer was christened jointly on the Seattle waterfront by Deborah Ritchie and Peggy Giersdorf, daughter and daughter-in-law of Robert and

Lori Giersdorf of Seattle, owners of the vessel. Immediately following the christening the vessel left for cruising in Alaska. In October this year she will move to Hawaii where

Catamaran CruiseLines, a division of Glacier Bay, will operate the ves- sel on week-long cruises from Hono- lulu to the major Hawaiian Islands.
