Thruster Operation
1. Turn on thruster by pressing both “on” buttons simultaneously until the lights stay lit;
2. Then operate the forward or aft “joystick” to run the thruster.
3. The thruster will only stay “ON” for about four minutes to protect it from overuse. After it turns off, you will have to turn it
“on” again!
4. Operate the thruster from only one helm at a time, lest you burn it out!
Do not overuse the thrusters! Operating them in “jabs” of 10-15 seconds at a time should be enough...they cannot be
run for extended times without shutting down when their thermal overload protective relays open!
4Q3: Trim Tabs
The boat is fitted with a set of Bennett Trim Tabs. These are wide “flaps”
attached to the aft end of the boat, under the swim step at the trailing edge
of the hull, operated hydraulically under the control of the skipper by rocker
switches at each helm station.
At low speeds, up to approximately six knots, the tabs do little, and should be
left in the “Bow Up” position (see below). But at speeds over this range, the tabs
begin to take effect and will help the operator lower the bow for more efficient
cruising.
The best way to adjust the tabs is to lower them while watching the “Speed”
indicator to get the highest speed at a given throttle setting by adjusting “Bow
Down”. If the tabs are “Bow Down” too much, the steering will get mushy and speed may drop off a little, and the tabs
should be adjusted “Bow Up” a little. Note that it will take time to make these adjustments; when the buttons are
depressed, they need to be held 2-5 seconds each time for change to be felt and observed (the best way to see the effect
of the tabs is by the knot meter and by observing the height of the bow relative to the horizon, most easily seen from the
lower helm station).
Because the trim tabs are so large, THEY MUST BE IN THE FULLY-BOW-UP POSITION WHENEVER THE BOAT IS TO BE
OPERATED IN REVERSE, otherwise the great water forces against the tabs may damage them severely, even tearing
them off the hull!
4R: Safety Equipment
4R1: Safety - Equipment Listing
This vessel is equipped with complete safety equipment
, listed on page 11.
4R2: Safety - Fire Suppression System
The boat has a fire suppression system built in to the engine room. It is
thermostatically operated, and if it operates because of a fire, it shuts down
the engine lest all the fire sup- pressant be ingested by the running engine’s air
requirements. A control on the helm (below the wheel slightly and to starboard)
Trim Tab rocker switches are on right of engine
switch and horn button panel.
