SAFETY
Safety is important in your daily cruising and should not be minimized. Review
where safety equipment is before cruising. Trying life jackets on is a good idea in
case they are needed latter.
Lifejackets are located in the stern lazarette and also on the fly bridge under
starboard aft facing seat. A few should always be out and ready, in fact we
recommend wearing them whenever working on the decks.
Flares are located in the salon in the upper cabinets on the portside of helm.
Fire extinguishers are located in the forward guest cabin, salon, aft cabin and
engine room.
The boat is equipped with a wireless LED searchlight. Rocker switch is marked.
Hand held remote located starboard side wheel.
It is a good idea to review what to do in case of an unexpected person in the
water... Man Overboard drills take a few minutes!
The throw ring is hanging outside the starboard doorway to the cabin. Again
practice is a good idea.
An air horn is located in the small stow away section above the wheel.

QUICK START
Before Starting Engines Checklist
Dinghy secured?
Grill covered?
All breakables stowed away?
Disconnect shore power, store cord
Power panel: double green dots ALWAYS ON; green dots ON for normal operation;
yellow dots ON as needed; red dots ALWAYS OFF
Open blinds for visibility
Check WOBBS: water (engine coolant), oil, belts, bilges and strainers
Check engine pads for signs of leaks
Close aft stateroom door to cockpit to keep diesel fumes out of the cabin
Starting Engines:
Put gear controls in neutral, throttle levers at slightly above “idle”
On “Engine Panel” of the DC Panel, flip starboard power switch to
ON for starboard engine. Buzzer will sound (low oil pressure
warning)
Push STARTING button for the starboard engine. When engine
starts, throttle back to a smooth idle. Buzzer should stop. Do not
try to start more than 30 seconds without a 2-minute “rest” period
Repeat procedure for port engine
Warm up at idle RPM
Check oil pressure for both engines: 30-90 PSI
Check for water coming out of both engine exhausts at the stern
Before Leaving the Dock:
Center the rudder
Untie mooring lines
Piloting from dock can be done at idle using forward and reverse of the twin props
Make sure engines are at idle before shifting gears. Make a slight pause at neutral before
shifting between forward and reverse
Underway:
Stow mooring lines and fenders
Keep watch for logs or debris in water
Monitor gauges
Keep engines RPM under 1300 until engines warm to 150 degrees
Normal RPM is between idle and 2200. ‘Latis’ cruises a very comfortable 8 knots @
1600 RPM with fuel consumption about 3 gals per hour. Do not exceed 2300 RPM for
more than 30 minutes – check engine temps!
Normal readings: Engine Temp 175-190 Oil Pressure 30-90 psi

6
Approaching Dock:
Put fenders out. We generally put fenders down on both sides when maneuvering in
close quarters. Have extra fenders ready if the vessel will make contact with the dock or
another boat
Attach bowline to cleat and run line out through the hawsehole, OUTSIDE the bow rail
and OUTSIDE fender lines toward mid-ship. Same procedure for stern and spring lines.
Station a member of the crew at mid-ship to tend the mooring lines
Engine throttle should be dead slow and rudders centered. Close maneuvering is best
done with forward and reverse maneuvers with twin props.
Mate ready to step off swim step (No leaping across water to dock!) and secure spring
line (most circumstances), then bow and stern. Often you will find a friendly person to
catch your dock lines and help you secure them.
Position mate on deck with a spare large fender with line attached.
Upon Arrival at Marina:
Secure all lines. Stern, bow and two spring lines at a minimum
If bow-in, be sure anchor is not protruding over dock walkway
Turn off engines (see “Stopping Engines” below)
Turn off electronics at both helm stations; replace covers
Connect shore power. First to the boat, then to the shore receptacle (30 amp power for
Latis)
If at an unfamiliar marina, be sure to check polarity of the shore power connection before
turning on the breaker at the dock
Stopping the Engines:
After operating at cruising speed, allow engines to idle a few minutes to cool down before
shutting them down (this usually happens naturally while tying dock lines or setting anchor).
You can also turn on the engine room VENTS to help cool the engine room.
On Engine Panel turn the far left STOP SOL breaker to the ON position
Push the port STOPPING button. Low oil pressure buzzer will sound
Turn off the port engine power breaker. Buzzer will stop
Push the starboard STOPPING button. Buzzer will sound
Turn off the starboard engine power breaker. Buzzer will stop
Turn OFF the STOP SOL breaker
Daily (Overnight) Checklist in Marina:
AC Input ON for shore power
Inverter ON – be sure it is charging
Keep an eye on the holding tank. The meter is located in the master stateroom head on
the sink vanity

7
Daily (Overnight) Checklist at Anchor or Buoy
Anchor light ON during hours of darkness.
Turn off unnecessary electrical items. Even unplugging appliances not in use will help
reduce the drain on battery power - turn off the power strip for the microwave and coffee
maker
Keep an eye on the holding tank. The meter is located in the master stateroom head on
the sink vanity
Mooring at Anchor:
All anchoring should be done with the engines running as the windlass uses a lot of
power
Turn on WINDLASS POWER on panel to the right of the helm. Anchor is lowered with
foot controls on bow deck below the Windlass. Lower the anchor while backing the boat
slowly from anchorage
Foot controls on bow below the windlass
Mate on bow to monitor length of chain going out and to troubleshoot if it gets tangled.
Anchor line is marked as indicated in the Operations Manual
When desired chain length is out, stop Windlass
Attach snubber lines to anchor chain. Use of snubber lines will give a more comfortable
anchorage as they act like springs to absorb tension on the line. Attach snubber lines to
the anchor chain beyond the anchor roller in order to take the “load” off the Windlass.
Secure snubber lines through bow hawseholes and to bow cleats.
Run out enough chain to take the tension off the Windlass
Back the boat at idle using just one engine to test the set of the anchor. Use a
combination of sighting objects in the harbor and GPS to confirm anchor set
Turn OFF Windlass power at the panel
STOP engines

8
First Thing Each Day:
If at anchor, turn OFF the anchor light
Check battery reserve on inverter panel (port side of wheel). If less than 12 volts,
consider starting engines to begin recharging house batteries before using any additional
electricity
Check fresh water tank level
Check holding tank gauge. If near full, it will be necessary to pump out very soon
Before Leaving Vessel:
DC power panel: turn freshwater (F.W.) Pump OFF
Cover electronics screens at both helm stations
Close curtains
Lock the cabin doors
If you are docked at an island, make sure no food is left out or accessible as critters will
come aboard

BOAT OPERATION
ENGINE INSPECTION
Remember to check WOBBS every morning: Water (Coolant), Oil, Belts, Bilge
and Strainer.
Access to the engine compartment is through the hatch near the port door. There
are wooden stairs that can be removed when working by raising the silver latch and
lifting the ladder up. You do not have to unscrew the bolts at the bottom step.
Water (Coolant):
This engine does not lend itself to an easy check of the level of Coolant in the
coolant reservoir.
The best method to check for coolant is to place one finger inside the reservoir. If
your finger touches coolant at any point when inside the reservoir, the coolant level
should be adequate.
If you notice overheating please open the coolant cap located towards the front of
the engine once the engine has cooled down.
Oil:
Port Engine Starboard Engine

10
Check the level of Oil in each engine by using dipsticks located on the side of each
engine, easily accessed from the center of the boat.
Look at the etch marks on each dipstick that indicate the proper oil level.
Only add oil if level is near the lower mark and DO NOT OVERFILL! Please
use a paper towel or oil rag, not the dish towels, to wipe off the dipstick. Ensure
the dipsticks are fully seated back into the tube when done.
Belts:
Check condition and tightness of the belts. If they feel tight, that’s about right.
Bilge:
Check the lower areas of the engine room for excess water. You will note the
amount when you first start and after that if it increases, check for causes.
Bilge under floorboard forward engine room
There are sorbs (diapers) under each engine. They will help identify if there are
leaks in the engine and to determine where they may be. Under normal operation
there are minimal drips, however if an engine is dripping significantly check for
the probable cause.
A manual bilge pump is located under the hatch near the entrance to the lower
stateroom.
