did we choose Navman over the wide range of the many manufacturers
available? Simple, they were prepared to assist us in an area that
we were unfamiliar, plus they have a good reputation throughout the
world for a quality product and a range whose only gap was
eventually filled with their delayed radar system.
is a low-profile, low power multifunction marine display or
data-helm with integrating GPS, sonar, fuel management and video
functionality into a daylight viewable high-resolution screen.
The hardware also displays the radar on screen. The Navman's 32 MB
regional chart gets you started for navigation, while the extra
C-Map's MAX technology are best for detailed chart data (we started
with the English channel). Later, we can hook it up to a security
camera for live deck monitoring, engine room surveillance or
underwater views... of canal basin?? Or even run a DVD player or
camcorder into the 8120 for entertainment benefits. The 8120
integrates well with the other on-board systems (instruments, DSC
VHF) to provide a choice of full or split screen displays. The speed
and depth transducers information is also fed into the 8120.
G-Pilot 3380this is a daylight viewable TFT display and provides outstandingly
clear information on heading status and key pilot data. The big
rotary control dial allows a course to be set with ease as well as a
user-friendly interface to the menu selections. Surrounding
the dial are port and starboard LEDís that flash to show pilot
course adjustments. This provides a level of comfort for the
questionable skills of JENAL's skipper with a single glance
at the screen, even in the dark of night. One-button dodge and jog
keys, easy selection of 90/180 deg turns and it even has graphical
capabilities to provide unique on-screen animations of the vessel's
intended actions and progress through a turn.

High Definition Digital Radar: This means exceptional detection of small or
distant targets, using advanced digital signal processing. This
processing ensures tracking and chart overlay can be displayed with
confidence. It presents targets better and rejects clutter using
digital Sensitivity Time Control (STC). Also screen-clutter from
rough weather is cleared away using sensitivity settings tailored
for our specific conditions. MARPA software allows us to select up
to 10 targets and compute their speeds and directions, which can be
particularly useful in the busy English Channel. Each target can be
tracked and progressed and we become alerted if any of them present
Complete Fuel Management:
An ingenious diesel fuel management system which monitors the fuel
flow with a positive displacement transducer on both the inlet and
return lines, to compute a highly accurate fuel consumption figure.
When combined with the speed data gained from GPS or paddle wheel in
the hull, valuable information about economy and range can be
displayed. The data is displayed on the 8120 monitor and is
particularly useful when determining optimum throttle settings for
maximum engine efficiency, according to the barge, the sea condition
and the barge load.
The added benefit will be balancing this
with hydraulic drive's trawling facility for optimum fuel economy.
This DSC 7200 Radio combines the most elaborate functions with extreme
ease of use. The large amber backlight display is easy to read and
an exclusive Navman feature is real-time forecasting, which shows
sudden weather changes. Major features include integrated and
independent DSC, various scanning modes, track-your-buddy (s0
beware), GPS interface, saved calls, MMSI ID storage and is fully
waterproof, which we hope doesn't need proving! This is mounted in
Because latter-day legislation dictates we have to have two VHF
radios aboard, we opted for a Navman handheld second one, this
enables us to also use it onboard the RIB.
