Fuel tanks
The Atlantic 85 uses two, four stroke petrol engines. The
boat has two fuel tanks accessed under the crew seat which
in normal operations feed their respective engines (port
tank feeds port engine and starboard tank feeds starboard
engine). The tanks hold 105 litres each, sufficient for the
boat to operate at full throttle for 2 hours and 30 minutes.
However, if operating at less speed the duration and range
can be significantly increased.
Fuel change-over blocks
In the event of a problem with one tank or its contents, it
is possible to run both engines off either tank individually.
The change-over blocks are located underneath the crew
seat which is accessed from the port side. When each hose
is connected to its own block, the boat engines are being
fed independently. If you attach the hoses to the same
block (either on the port or starboard side), the respective
tank will then be feeding both engines. Consider that your
range will be reduced if you are feeding both engines with
one tank.
Navigation and communications equipment
On the console in front of the crew seat is the navigation
and VHF communication equipment. The Atlantic carries
one VHF, one SIMS (consisting of two workstations, both
independently capable of displaying charts, radar, helm,
DF, battery voltage and alarms), two GPS chartplotters/
radar and directional finding equipment, which can be
used to locate VHF transmissions and distress signals from
emergency position-indicating radio beacons (EPIRBs) and
personal locator beacons (PLBs).
Chart light and MOB alarm
Underneath the crew console there is a red light to allow
charts or notepads to be used at night without using a
torch or other white light. The switch for the chart light
is located on the central console between crew seats
two and three. This ensures that the crew retain their
night vision. The grey disc to the left of the light is the
MOB alarm speaker.
White flare stowage
3 white flares are located underneath each side of the crew
seats (6 in total) these are used for illumination although
the official maritime function is collision avoidance.
NOTE
White flares are not a distress signal.
