Electro-Nav Now
Sole U.S. Distributor
Of BEN Speed Logs
Electro-Nav president Robert
Negron has announced that his
company, one of the nation's top
marine electronic distributors, has
been appointed sole U.S. repre-
sentative for the entire BEN
Electro-Magnetic Speed Log line.
The BEN Speed Log is a com-
bination ship speedometer/odom-
eter that saves on fuel costs, in-
creases operational efficiency, and
interfaces with existing equip-
ment like sat/nav, radar and col-
lision avoidance gear to achieve
greater navigational accuracy. It
improves coordination between
vessel and home office, and expe-
dites schedule maintenance.
The BEN can measure speeds
as low as 5 feet per hour, which
makes it an effective maneuver-
ing aid, even for supertankers.
It is also very sensitive to speed
variations and will even register,
at once, the speed drop caused
by a snagged net on a moving
fishing vessel, permitting imme-
diate action.
One important feature of all
BEN Speed Logs is the retract-
able transducer which mounts
flush on the hull. There are no
external probes to bend or break,
maintenance work is performed
from inside the vessel and instal-
lation and calibration can be com-
pleted in just one watch period.
The BEN Speed Log line in-
cludes a wide variety of logs,
transducers and auxiliary speed
and distance indicators, permit-
ting substantially custom outfit-
ting for vessels of any size, in
any service.

Maritime Reporter/Engineering News
Voith
Water Tractor
In the fifties, Wolfgang Baer
developed the concept of a
ship-handling tug in which the
drive and control are arranged
forward and the towing gear aft.
The decision of far-sighted
towing companies made the
introduction of this new type of
vessel feasible. Since then
many years of experience have
led to a world wide break-
through of this idea.
Called the Voith Water Tractor,
this ship-handling tug has
established an unequalled
reputation in modern ports.
It is therefore understandable
that now and again attempts
are made to copy this concept.
However, the Voith-Schneider
Propeller is to the original
Voith Water Tractor what the
rotor is to the helicopter.
In addition to the hundreds
in service there are today
alone 66 Voith Water Tractors
with powers up to 4.000 HP
per vessel under construction.
We'll be pleased to inform you
in greater detail.
Stanley E. Rauhut has been
named to the post of vice presi-
dent and counsel of Samson Ocean
Systems, Inc., Boston, Mass., ac-
cording to an announcement by
Jerry J. Jones, president.
In his new post, Mr. Rauhut
will be primarily involved with
the Samson Undersea Services
Division, which operates diving
support vessels and provides hy-
perbaric welding, nondestructive
testing and unmanned vehicle
services throughout the world.
Mr. Rauhut joined Samson
Ocean Systems, Inc. in 1976 as
their counsel, and previously
served with Brown & Root, Inc.
on their legal staff. He is a grad-
uate of the University of Texas,
School of Law, is licensed to ap-
pear before the Texas and Mas-
sachusetts Bars, and the Federal
Courts of the 1st and 5th Cir-
cuit Courts of Appeal, and is a
member of the American and
Houston Bar Associations and the
Maritime Law Association of the
United States.
