ARTHUR FOSS
Tacoma Boat Building
The tractor tug Arthur Foss, fi-
nal vessel in a series of four built
by Tacoma Boat Building Com-
pany of Tacoma, Wash., for Foss
Launch & Tug Company of Seat-
tle, was commissioned during 1983.
Like the three sister vessels, the
3,900-bhp Arthur Foss features a
cycloidal propulsion system that
enables it to produce thrust in any

hemicals for Tough
Marine Operations
At Magnus Maritec, we have been developing and
supplying hardworking, cost-effective chemical
products to the marine industry for over 25 years.
Our diverse line of innovative products is backed
by dedicated, on-time service, which owners
depend on for efficient operations.
High performance and dependability is why
COLORCOOL ™ is popular for freshwater-cooled
diesel engines. A liquid nitrite-chelate water con-
ditioner, COLORCOOL T" inhibits corrosion and
scale formation on all internals of the cooling
system. Color indicator warns when the pH level
drops to an unsafe level. Work boat operators also
depend on our heavy-duty fuel oil additive, COM-
BUSTION CATALYST. This advanced, highly con-
centrated liquid catalyst dramatically improves fuel
oil combustion characteristics in diesel engines.
Our MAGNAKOTE® rust-retarding tank and void
space coating has proven itself superior for steel
corrosion protection.
direction without changing its
heading.
The new boat can move side-
ways, turn a full circle in very lim-
ited space, and come to a complete
stop in approximately its own
length. The capabilities allow the
tug to assist ships and tows in a
minimum of time and with maxi-
mum safety.
The Arthur Foss has an overall
length of 106 feet, beam of 38 feet,
and draft of 17 feet 4 inches. Pro-
pulsion is provided by twin GM
Electro-Motive Division 16-645-E6
diesel engines, each rated 1,950
bhp at 900 rpm. The two Voith-
Schneider, vertically oriented cy-
cloidal propellers have a blade or-
bit diameter of 3,200 mm (126
inches); each of the five blades is
2,006 mm (79 inches) long. The
Voith-Schneider units were chosen
after an in-depth, 2Vfe year study
by Foss. The conceptual design for
the tractor tugs was by the Foss
design committee; The Glosten As-
sociates of Seattle was the naval
architect.
The tug's capacities include
50,550 gallons of fuel oil, 4,500
gallons of lube and hydraulic oil,
and 5,400 gallons of fresh water. A
crew of six operates the vessel.

EL AUDAZ
Bender Shipbuilding
Bender Shipbuilding and Repair
of Mobile, Ala., has delivered the
225-foot El Audaz, the yard's fourth
big tuna purse seiner in a four-
boat order for Mexico. Immedi-
ately following her outfitting the
El Audaz cast off with her sister
ship Centauro Del Norte for fish-
ing in the Pacific.
Main propulsion is provided by
a medium-speed, Electro-Motive
Diesel 20-645-E7 engine produc-
ing 3,600 bhp at 900 rpm. Power is
transmitted to a 4-bladed, highly
skewed Rice propeller through a
Falk reduction gear. Main engine
controls were supplied by Mathers.
Auxiliary power is provided by
three Caterpillar D3408 diesels,
each producing 285 kw at 1,800
rpm. The main hydraulic power
source is also a Cat D3408, which
develops 500 bhp at 2,100 rpm.
