OUTSTANDING WORKBOATS OF 1988

This special review highlights some of the most notable and im- portant workboats delivered by

U.S. boatyards during the past year. Each selection in this award- winning group features its own dis- tinctive stamp of performance ex- cellence and fine craftmanship.

AARON MCCALL

Gulf Craft

Gulf Craft, Inc., Patterson, La., delivered the world's second largest crewboat, the Aaron McCall during 1988.

The 155-foot, 84-passenger crew- boat, the sister boat of the Blair

McCall, which was delivered last year, was built for McCall Enter- prises of Cameron, La.

Unlike her sister, the Blair

McCall, which is equipped with five

Cummins engines, the Aaron

McCall is powered by six Cummins

KT 1150M diesel engines coupled with Twin Disc MG-518 2.5:1 ratio reduction gears. Each engine pro- duces 680 shp at 2,100 rpm. The

Aaron McCall's propulsion equip- ment also includes Aquamet stain- less steel shafts and Columbian Bro- nze four-bladed 40-inch by 36-inch propellers.

Electrical power aboard the Aa- ron McCall is provided by two 50-

Photos (clockwise from top left): U.S. Enter- prise (Halter Marine), Sajo Victoria (Camp- bell Shipyard), SuperAmerica (Quality Ship- yards), and the Seattle Enterprise (Bender

Shipbuilding & Repair).

Besides a 180-long-deck-ton ca- pacity, the aluminum crewboat fea- tures the comforts of luxury accom- modations for both the crew and passengers. All interior living com- partments are air conditioned and heated by means of a water-cooled

Carrier unit. Three staterooms pro- vide sleeping accommodations for six crew members, while both pas- senger compartments yield seating for a total of 84 passengers.

The aft steering station, which is located just atop and behind the pilothouse, provides the captain with 360-degree visibility and ef- fortless handling when unloading and loading supplies. All six Cum- mins engines are also controlled via the aft steering station by way of the

Kobelt air controls. A Raytheon

VHF radio and a Realistic P/A sys- tem, as well as the oil company's pri- vate radio in the aft steering station provide communications between the captain and platform and deck crews.

The Aaron McCall's pilothouse is fitted with a complete set of elec- tronics. It features two Furuno ra- dars, two Raytheon loran plotters, a

Comnav autopilot, a Raytheon VHF radio, a Stephens single side band radio and a Datamarine depth re- corder.

GUIA/LIDER

Houma Fabricators

In the first quarter of this year,

Houma Fabricators delivered the tractor tugs Guia and Lider to the

Panama Canal Commission. The sister vessels both have Voith-

Schneider cycloidal propulsion sys- tems which feature 360-degree thrust for outstanding maneuvera- bility. The tugs are used to assist and tow ships through the narrow

Panama Canal and locks.

The 95-foot tractor tugs are pow- ered by two 1,500-hp EMD diesel engines that generate a bollard pull of 85,000 pounds. The tractor tug concept is enhanced by 58,000 pounds of side pull which allow the

Guia and Lider to hip up to a ship and maneuver it into tight places that prove to be troublesome to con- ventional tugs.

The delivery of the Guia and Lid- er brings the number of vessels recently delivered by Houma Fabri- cators to the Panama Canal Com- mission to five. The 3,000-hp twin- screw harbor tug Esperanza was de- livered in 1985, while the 3,000-hp

Chagres was outfitted as a dredge tender and delivered in June 1987.

In addition, a 130-foot salvage- diving barge complete with machine shop, salvage crane and decompres- sion chamber was delivered in Sep- tember 1988.

Houma Fabricators was recently awarded a contract by the Panama

Canal Commission to build another tractor tug identical to the Guia and

Lider. The contract contains an op- tion for a sister vessel. The Commis-
