Outstanding (continued) gine room taps. A Raritan massera- tor sanitation system is installed for pollution control.

The pilothouse is equipped with two electro-hydraulic steering sta- tions, with one facing aft for backing down on rigs. Stainless steel hydrau- lic tubing is used throughout the boat.

The off-ship firefighting system, unusual for a crewboat, consists of a keel-cooled Detroit Diesel 3.53 en- gine driving a Hale 700-gpm pump at 150 psi feeding an Elkhart 292 monitor. A feature of this system is its portability; when not in use the monitor can be stowed to avoid damage during cargo-handling oper- ations. It features an easy-on/easy- off coupler to allow quick response to any emergency.

OTTO CANDIES

Halter-Lockport

The Lockport. La., shipyard of

Halter Marine, Inc. recently deliv- ered the innovative triple-screw tug

Otto Candies, first of two ordered by Otto Candies, Inc. of Des Alle- mands, La. The 140-foot, $5-million vessel, described as a go-anywhere, do-anything tug, combines conven- tional and azimuth drive technology in one boat.

The Otto Candies, with outboard

Niigata Z-Peller drive units and conventional center-line propeller, all in nozzles, will provide her owner with both domestic and internation- al towing capabilities. This design allows for routine engine mainte- nance even when carrying payloads by shutting down either outboard engine while running the center-line engine. In any condition, the vessel can continue under way with excel- lent maneuverability.

With the outboard Z-Pellers in nozzles, the joystick control may be moved forward, aft, port, or star- board and the vessel will respond almost instantly in any direction.

This system will allow for the han- dling of tremendous loads in the tightest of spots, eliminating the need for multiple tugs in many off- shore applications.

The Candies tugboat has a beam of 42 feet, depth of 20 feet, and loaded draft of 19 feet. She is pow- ered by three GM Electro-Motive

Division 16-645 E6 diesels with a total output of 5,850 bhp at 900 rpm. The centerline engine has a

Reintjes WAV-2250 reduction gear supplied by Karl Senner, Inc. of

New Orleans.

The towing winch is a Markey

TDSDS-36 driven by a GM Detroit

Diesel 8V-92 engine. The hydraulic windlass was also supplied by Mar- key. The firefighting system in- cludes a 2,000-gpm pump and two monitors—a 1,000-gpm unit with lo- cal control and a remote-controlled 1,000-gpm unit. Fuel capacity is ap- proximately 85,000 gallons and fresh water 35,000 gallons. Accom- modations are provided for a crew of 14.

Without the house top, the Otto

Candies at launching weighed 500 tons; a comparable conventional tug would weight some 150 tons less at this stage. The difference is Ice

Class "C" construction and a heav- ier stern that contribute to both sta- bility and versatility.

STEP UP WITH

WESTPORT

Now the Source of Fiberglass Vessels to 120 Feet and 30-Knot Speed

Westport—the source for large fiberglass/Airex

Coast Guard certified tour and excursion vessels finished to yacht quality standards— now offers boats up to 120 feet. In fact, no other builder can match West- port's size range in fiber- glass... Examples of our capabilities currently afloat: The 150-passenger, 80-foot GLACIER SPIRIT tours the waters of Prince

William Sound in Alaska.

The 80-foot AVALON EXPRESS a 150-passenger high speed ferry, makes the run from Los Angeles to Catalina at 20 knots. The new 90-foot CATALINA EXPRESS will make the same run at 25 knots... Not only do our fiberglass passenger boats have the "yacht" look and finish, they can out-perform metal boats where it counts—speed, maintenance, and cost...

Westport's craftsmen can customize the lines of a new mold to meet different speed and load require- ments for hulls from 90 to 120 feet. With this mold,

Westport now offers the widest range of fiber- glass capabilities in the industry...Two versatile molds from 65 to 120 feet, state-of-the- art automated fiber- glass equipment, an efficient modern plant, and a friendly crew allow us to deliver the best values available in fiberglass passenger and work boats...

Discuss your next tour or other working boat with us. Both your passengers and your accountant will enjoy stepping up with

Westport.
