Bender Delivers Fourth Tuna Boat
Bender Shipbuilding and Re-
pair, Mobile, Ala., recently de-
livered the 3,600-horsepower, 225-
foot tuna boat "El Audaz," its
fourth tuna purse seiner in a
four-boat order.
When the shipbuilder finished
the outfitting, the El Audaz cast
off with sister vessel the Cen-
tauro Del Norte from Mobile for
fishing in the Pacific.
"This represents something of
a milestone for us," explained
president Tom Bender Jr. "We
have successfully executed one
of the most advanced designs for
vessels in this size range. Com-
pleting this fully molded hull
with aluminum superstructure,
together with their other sophis-
ticated systems, represents an
advancement of our proven ca-
pabilities. And we did it not
once, but four times. We thank
our Mexican friends for award-
ing us this contract and thus
recognizing that we are not just
another shipyard."
The El Audaz was christened
by Maria Elena Estrada Del
Castro Y Castro, wife of the Di-
rector of Coordination and Pro-
motion for the Mexican Govern-
ment organization, Conasopa.
The steel-hull tuna boats are
capable of carrying 1,200 tons
of fish, 85,000 gallons of fuel,
without fishwells, and approxi-
mately 200,000 with fish wells,
and 8,500 gallons of water at a
swift 16 knots.
The only part of the two ves-
sels made of aluminum are the
pilothouses which are reinforced
for helicopter landings.
Main propulsion power is pro-
vided by a 20-cylinder EMD die-
sel (Model 20-645-E7) which pro-
duces 3,600 horsepower at 900
rpm.
This power is transmitted to
a Rice, four-blade, highly skewed
propeller through a Falk gear
box. Main engine controls are by
Mathers of Seattle.
Auxiliary power is provided by
three Caterpillar D3408 diesel en-
gines each developing 285 kw at
1,800 rpm. The main hydraulic
power source is a Cat 3408 which
develops 500 hp at 2,100 rpm's.
Steering gear is hydraulic, a
Wagner LAZ-16-35 furnished by
W.E. Hough of Seattle.
Four 100-hp Vilter compres-
sors are used to power the am-
monia refrigeration system and
the bow thruster is Michigan'
Jastram 49" prop model BU60,
powered by a GM 12V71 diesel
engine (400 hp at 2,100 rpm).
The main hydraulic systems
are furnished by Marco of Se-
attle. They include the WS 454
Super Seiner II Seine Winch,
3020 Cork Line Winches, WO 332
Brailing Winch and B56A Power
Block.
Also supplied were miscellane-
ous Gearmatic winches for
vanging, topping, choking and
strapping. Incorporated into the
hydraulic system is a Slattery
"Alaska Marine" deck crane on
the forward deck and a Morris
Whaley ring stripper. Naviga-
tional aids include a Sperry 8T
autopilot and a Mark 37 gyro-
compass.
Electronics, furnished by Hon-
or Marine of San Diego and in-
stalled by Sassman Electronics
of Mobile, include two Furuno
FR1011 radars, Whelen strobe
light, Furuno FE-8130F echo-
sounder, TAIYOADF, Furuno
