MARINER'S GUIDE TO GPS
No question about it: GPS lets you fix your position more precisely than any other technology.
Unfortunately, the way most GPS sys-
tems fit your needs has been considerably less precise.
That's because most companies only give you one
model to choose from.
But at Trimble, we've always thought your naviga-
tion system should fit your bridge, your work and your
lifestyle. That's why we offer GPS in eight very dif-
ferent systems. Here's how to decide which one's right
for you:
Charting If you want the ulti-
mate in high-tech navigation, our
NavGraphic IP is the most sophis-
ticated GPS
Interfacing Both the NavGraphic and the NavTrac have
extensive interfacing capability, but if you need a rugged
system to act as the coordinating link of a fully-integrated
nav station, the 10X™is the perfect choice-especially
in large installations where distributing control is
important. The 10X processing unit can handle two
control heads, one for the nav station and one on deck.
receiver com-
mercially available. Integrating
CD-ROM, LORAN, GPS, and micro-
computer technologies, it plots a mov-
ing image of your boat right on a real
NOAA chart. It's the most direct
navigation device ever developed.
Ease of Use If
you don't need
charting, but
like the way
graphics simplify
navigation, the
NavTrac™ GPS gives you a high-resolution screen in a
smaller, more economical package. Its unique steering dis-
play shows you a perspective view of your boat's progress.
And makes navigation as easy as driving down a road.
Portability If you've got more than one boat, or if your
travels will take you over land or into the air, then you
need a system you can carry.
The TransPak™ puts a com-
plete three-channel GPS
receiver and antenna into
'a package the size of a pair of
binoculars. Splash-proof, mud-proof,
shock-proof, this rugged little unit will go anywhere
you do. And our new TransPak IT" gives you the same
portability with more waypoint storage and an I/O port.
GPS Sensors If you've already got a nav-
igation system you're familiar with, you
can upgrade to GPS in one quick step.
Our Acutis""GPS is a complete 3-channel
receiver and antenna integrated into a
ruggedized module that's mounted just
like an antenna. If your LORAN, chart-
plotter, or radar accepts NMEA-0183, GPS
is as easy as connecting
a cable.
For even greater pre-
cision, we also offer a Six-Channel
GPS Sensor that accepts differential
corrections and gives you four I/O
channels.
H
Differential For scientific and industrial
applications, our 4000Reference LocatorTl"
is the industry-standard differential
base station. It transmits differential
corrections to roving receivers, letting
them fix their positions to accuracies
of a few meters.
So you can see, at Trimble we offer more than just
high technology, we offer you a choice. Maybe that's why
our systems are being used on every-
thing from oil exploration ships to
luxury yachts, from freighters to
fishing boats.
If you'd like to know
more, just call or write for our Complete
Mariner's Guide to Trimble GPS. And we'll
show you why Trimble GPS is the most precise
navigation system—in more ways than one.

new era in the ferry traffic in the
Baltic.
Masa-Yards and Silja Line have
been actively developing the "Baltic
Ferry Concept" since the late fifties
and early sixties. The 665-1/2-foot
Silja Serenade, although it incorpo-
rates many of the design achieve-
ments of the past, is unique because
of the Silja Promenade. This "main
street" is a huge atrium on her main
deck, with a length of 470 feet,
width of 27 feet and height of five
decks. The promenade is accented
by skylights atop and a glass wall at
the aft end of the ship, those provid-
ing passengers with a view of both
the sea and sky. Restaurants, shops,
and other recreational and enter-
tainment facilities are accessible
from the promenade.
In addition, two accommodation
blocks are situated on each side of
the promenade, with cabins facing
either the sea or the main street.
The Silja Serenade will have a
gross tonnage of 58,376 tons,
breadth of 103 feet, and design draft
of about 22 feet. She has a passenger
capacity of 2,500 in 952 cabins. Ad-
ditionally, the Silja Serenade can
also accommodate 450 cars or 60
trucks.
SPIRIT OF BOSTON
Dinner/Excursion Boat
Blount Marine
In the first quarter of 1990, War-
ren, Rhode Island-based shipbuild-
er Blount Marine Corporation deliv-
ered the dinner/excursion boat M/V
Spirit of Boston to Cruise Interna-
tional. The Spirit was the first boat
launched from Blount Marine's new
shipway.
Built for Holiday Cruise II, a sub-
sidiary of Cruise International
headquartered in Norfolk, Va., the
600-passenger Spirit of Boston op-
erates in Boston Harbor. At her
launching, she was called "the finest
(one) of her kind," by owner Rich-
ard D. O'Leary, president of
Cruise International.
