DAILY CHECKLIST
MAIN ENGINES
Check bilge for abnormal amounts of water.
Use manual bilge pump to remove water.
Check fresh water, cooling reservoir on each engine.
Water and antifreeze coolant in the expansion tank should be about 2” below full
to allow for water to expand.
Check the engine oil level on each engine.
Level should be between the notches on the dipstick. DO NOT OVERFILL
Check for any water or oil leaks on the engines or in the bilge.
ENGINE OPERATION
STARTING ENGINES
Start engines only after daily engine checks have been accomplished. DO NOT
ATTEMPT TO START BOTH ENGINES AT THE SAME TIME
To Start:
Position port gearshift lever in NEUTRAL.
Position throttles to IDLE.
Turn on key for port engine, yellow “pre-heat” light and red engine
warning light will illuminate.
When “pre-heat” light goes out, turn key to start.
Release key once engine starts.
Leave throttle at idle
Red warning light should go out within 30 seconds.
Check for oil pressure within 30 seconds.
Repeat for starboard engine.
Failure of the engines to start is most often caused by not having the shift levers properly
placed in the neutral detent position. Check gearshift position at both helms if engines fail
to turn over.
When the keys are turned on, the buzzer will sound until the engines are “pre-heated”.
It can be hard to hear the second engine start over the noise of the first engine. Monitor
the tachometer for an indication the engine has started.
Visually verify that cooling water is flowing from the exhausts of each engine, port and
starboard below the swim step. Idle engines until the water temperature gauge reaches
120° F.
STOPPING THE ENGINES
Turn off the engines only after allowing engines to idle for at least 5 minutes. This allows
time for the engines to cool down. Never turn off hot engines.
Turn keys to the off position.
GAUGES & ALARM PANELS
Gauges and Alarm panels are located on the instruments panels at both helm stations.
The US Marine gauges are analog type (needle/gauge) and register engine conditions
from a low to high condition. These gauges require that you monitor them while the
engines are running to insure they remain in the “normal” range.
Conditions the gauges monitor include:
ENGINE WATER TEMPERATURE
ENGINE OIL PRESSURE
ELECTRICAL (ALTERNATOR) STATUS
MONITOR GAUGES AND ALARMS AT ALL TIMES
Remember, this is a twin-engine vessel. Monitor each set of gauges and alarms.
IF ALARM SOUNDS OR GAUGES ENTER ABNOMAL RANGE
TURN OFF ENGINES
DEPARTURE






After starting both engines turn on needed electrical equipment.
Disconnect AC shore power cord by
o Turning off Master Breaker.
o At dockside, turn circuit breaker off.
o Unplug power cord and stow on board.
Check to be sure your planned course is clear of other boats, debris and all lines
are onboard.
Clear all dock or mooring lines and secure onboard.
Secure fenders after vessel is clear of all obstacles.
Do not exceed 1800 RPM until engine temperature reaches 165°.
CRUISING


Always have proper charts at hand while underway.
Check engine gauges.
o Oil pressure should be 20-60 psi
o Water temperature should be 190° - 250°
o Ammeter should read between 12 & 14 volts
If engine buzzer sounds while cruising, throttle back engines, shift to neutral and check
all engine gauges immediately.

Ideal cruising speed is between 2000 RPM and 2200 RPM (12-15kts). The most
fuel-efficient cruising speed would be 2000 RPM. Above 2200 RPM there is little
speed gained but a major increase in fuel consumption.
ARRIVAL AND DOCKING



Know where you are going. Call ahead on the radio to the Harbor Master for a
berth assignment.
Proceed at dead slow speed in the marina.
Have fenders out and docking line ready before entering the marina.
Instruct deck hands as to your intentions and their duties.
Once the vessel is in the slip, secure with adequate mooring lines for the
conditions.
After letting engines cool down, turn off engines.
Turn off electrical equipment.
Connect shore power.
CONNECTING SHORE POWER









Make sure the AC line switches are off. (LINE 1, LINE 2)
Connect shore power cord to receptacles on starboard side using the splitter.
Connectors are twist to lock and must be pushed in and twisted. Screw down
lock-ring.
Make sure dock circuit breaker is off.
Plug cord into dock receptacle and twist to lock.
Turn on dock circuit breaker.
Turn on Line 1 & Line 2 breakers.
AC indicator light on the inverter panel will indicate AC is present.
Check AC voltage for proper readings.
Note: If dock circuit breaker trips the vessel is using more amperage than the circuit can
supply. Turn off any unnecessary AC appliances.
ANCHOR WINDLASS OPERATON
Anchorage is provided by a Lewmar 12volt electric windlass, a Bruce anchor and 100’ of
chain and 150’ of rode. The Bruce design provides a good hold and under most
conditions is easy to set. The chain is marked every 25’ with red paint.
The master Windlass switch is located on the main electrical panel in the salon, starboard
side aft.
The switch must be on to operate the windlass. The switch should be in the off position
when not operating the windlass. This prevents accidental operation of the windlass while
walking on the foredeck.
To raise or lower the anchor there are two foot buttons, on the port foredeck near the
windlass. Each is marked by an arrow indicating the direction the chain will move, in or
out.
Note: the engines must be running to provide full power to the windlass. You should
always keep the engines running when retrieving or setting the anchor for vessel control.
When setting the anchor, first remove the safety line from the anchor. Run the windlass
to let out a little chain and then free the anchor from the pulpit. Continue to lower chain
until you have enough chain out to set the anchor. Set the anchor with quick movements
of the engine shift levers into then out of reverse. Once you feel the anchor has set, run
out sufficient chain to achieve the desired scope. Turn off windlass DC master switch.
NOTE: From dusk to dawn, the anchor light must be on when anchored or tied to a Park
bouy.
To retrieve the anchor: Start the engines and allow to warm up. Turn on the DC master
switch. Using the foot button, slowly bring in the chain. It may be necessary to drive the
boat forward a little to reduce the load on the windlass. The chain should always be
straight up and down. Pause occasionally to allow the windlass motor to cool and to
allow the boat to move forward under the pull of the chain and anchor.
If you have anchored in a mud bottom it will be necessary to clean the chain as it comes
in. Lifting the chain in and out of the water by hand can do this
Be careful when bringing in the last few feet of chain and the anchor. Do not allow the
anchor to hit the hull or the bow pulpit. Bring the anchor into the bow pulpit very slowly
to allow the anchor to center in the roller.
Secure the anchor with the safety line and turn off the DC master switch.
BATTERIES AND SWITCHES
“Latitude Adjustment” has a total of seven batteries. Each engine has it’s own starting
battery located just forward each engine. The ‘House’ battery is located between the two
engines amidships. The inverter is operated by four batteries located on either side of the
cockpit lazarette aft.
Engine Batteries: A large battery is reserved for each engine. An electrical isolator
prevents you from using these batteries for ‘house use’.
House Battery: A large battery supplies 12v DC power to operate the lights, electronics
and refrigerator. On the electrical panel is a meter to monitor the battery
Inverter Batteries: Four golf cart batteries, two on each side of the cockpit lazarette area
ganged together to power the inverter. These batteries are charged only when on shore
power or when the starboard engine is running. The inverter and control is located under
the aft stateroom bed. There is a remote display on the electrical panel.
Battery Switch Panel: Starboard side, next to the helm is a locker that houses the rotary
battery switches, DO NOT ADJUST THIS SWITCH. As set, it allows proper charging of
the batteries and provides the proper power to the yacht. Changing position could result
in failure to start or charge one or all of the electrical systems. Only incase of an
ELECTRICAL EMERGENY should you turn these switches to off.
Battery Chargers: “Latitude Adjustment” is equipped with a 2500watt Trace Inverter.
This inverter also acts as a battery charger for the inverter batteries when connected to
shore power. There is also a ProMariner battery charger at the forward end of the engine
room that charges the house and engines when connected to shore power. All batteries
are charged when both engines are running by way of the engine alternators.
BILGES & SUMP PUMPS
There are six bilge pumps on “Latitude Adjustment”. Three have automatic float switches
that activate when the water level reaches a certain level. There are also three manual
pumps that are activated by switches at the either helm. Run the manual sump pumps
daily to ensure as little water as possible is in the bilges.
There are shower sump pumps for each shower. These sumps collect the ‘gray’ shower
water from below water line and pump it over the side. These pumps activate
automatically as needed.
NOTE: SHOWERS USE A LOT OF WATER. TO CONSERVE WATER USE THE
FLOW BUTTON ON THE SHOWERHEAD TO TURN OFF THE WATER WHILE
SOAPING UP.
FUEL SYSTEM
FUEL TANKS: There are two fuel tanks that hold 100 US gallons each. They are located
outboard of each engine. The fill point is located in the deck above the tank, one on each
side. ALL FUEL IS #2 DIESEL.
CHECKING FUEL LEVEL: There are two fuel gauges at the lower helm. Refuel at
regular intervals, gauges can fail.
FUELING: There are two fill points, one on either side deck mid-ship. They are screw in
caps that need a key. The same key works for all deck fills and waste pump out caps. The
key is located in the galley, in the tilt-out drawer. All caps are marked, do not confuse
these markings and put fuel in the waste tank.
FUEL MANIFOLD: The fuel manifold is located on the forward bulkhead of the engine
room. The manifold is set to provide each engine fuel from its respective tank. DO NOT
CHANGE THE POSITION OF THE MANIFOLD VALVES.
CABIN HEAT
The hot water from the engines will provide cabin heat while underway. There is a ‘three
position’ toggle switch at the lower helm. Positions are ‘engine’, ‘system’ or ‘off’. To get
heat while underway set the switch to the ‘engine’ position and adjust the thermostat.
There are thermostats in the forward and aft staterooms as well as in the salon. There are
blowers/heaters throughout the boat; each blower has a ‘low’, ‘high’ and ‘off’ position.
The fans begin to operate when the temperature of the water in the system reaches a preset level. To use the Webasto furnace while at anchor or on moorage, switch to the
‘system’ position. Everything else works the same, only now you’re using the furnace for
the heat source. While the furnace is operating it will heat the water in the Ever Hot tank.
To use the Ever Hot without heating the cabin spaces, turn all fan units to the of position
(turning off the cabin heat) and leave at least on thermostat set at 80 degrees. This will
keep the furnace heating the Ever Hot tank.
SAFETY EQUIPMENT
FIRE EXTINGUISHERS
There are three marine fire extinguishers on “Latitude Adjustment”.
 Inside companionway to port.
 At lower helm.
 Inside forward hanging closet.
Become familiar with all three fire extinguishers are prior to departure.
FLARES
There are hand held flares and aerial flares under the aft dinette settee.
EMRGENCY WHISLTE/HORN
There are emergency whistles in the flare kit under the aft dinette settee.
There is an emergency horn, also under the aft dinette settee.
LIFE JACKETS
There are eight adult and two child life jackets under the aft dinette settee.
FIRST AID KIT
The First Aid kit is in the aft stateroom, under the vanity sink.
Please locate and know where each of these safety items is located. In an emergency, you
won’t have time to look through this book to find something.
Everyone must wear a life jacket while in the tender. IT IS THE LAW. Children should
have a life jacket on at all times they are outside of the cabin.
FRESH WATER SYSTEM
Tank Capacity: There is one fresh water tank. The capacity is 77 US gallons. The fresh
water tank is filled from the sun deck, on the port side aft. Don’t try to fill the waste
tanks. Use the blue ‘potable water’ hose only to fill the water tank.
Checking Water Level: The fresh water tank gauge is located on the Master AC panel at
the top. Depress the button on the left side to display the current water level.
Water Heater: There are three ways to produce hot water. When the Starboard engine is
operating it heats water in the hot water tank. When connected to shore power on Line 2,
the AC provides power for the electrical heating element. When the Webasto heater is
operating it will also heat the water in the hot water tank. NOTE: see Cabin Heat on pg 8
for Webasto operating instructions.
NOTE: Do not allow the fresh water pressure pump to run when the water tank is empty.
SEA STRAINERS
The seawater strainers for the engines are aft of each engine, inboard. The seacocks for
each engine are below and aft of each seawater strainer. To remove and clean the strainer
screen you must first close the seacock. The seacock is open when the handle is in-line
with the valve, and is closed when the handle is 90° to the valve.
CAUTION, NEVER OPEN SEA STRAINERS UNTIL THE SEA COCK IS
CLOSED AND SECURED!
If the seawater strainers become filled with seaweed they need to be cleaned to prevent
engine overheating. Remove the wing nut (should be finger tight) and plastic washer on
the top of the seawater strainer, and then remove the cover plate. Now remove the
strainer screen, it should pull straight up.
The screen can now be cleaned with a soft brush and water. Check inside the unit for any
foreign objects before inserting the clean strainer. To install the clean screen reverse the
process. When the seawater strainer is completely reassembled, open the seacock.
SANITATION SYSTEM
Heads: There area two marine heads (toilets), each with it’s own holding tank. The heads
are manually operated. Proper use of the heads should be explained on the Captains
checkout. The heads discharge into the holding tank in normal situations. Beyond the
three-mile limit it is legal to discharge overboard. Since your cruising area is within that
limit, do not change the position of the ‘Y’ valve or energize the macerator pumps. Fines
for discharging waste within the three miles are steep.
DO NOT PUT ANYTHING INTO THE HEAD THAT WASN’T FIRST IN YOU!
A plugged head has ruined many vacations. “Latitude Adjustment” has two heads. That
would allow you to continue at a slight inconvenience. There are zip close bags in each
head in which to place your soiled paper. Each bag is large enough to last a couple of
days and can be disposed of with the trash at your next port of call. Please do not put
toilet paper or anything else, into the head. There are head repair kits under the aft dinette
settee.
Holding Tank Monitors: There are indicator lights located in both heads that illuminate
when the holding tank is near full and the head should not be flushed again until the
holding tank can be pumped out.
Waste tank pump-out points are on the starboard side. The aft tank pump-out is on the
Sun Deck aft starboard corner. This is also where the fresh water fill is located. Be sure
you are opening the correct cap. The forward tank pump-out is located in the side deck.
APPLIANCES
Stove & oven: The stove and oven operate on LP/propane gas only. The LP tank is
located in the Sun Deck storage locker. Turn the valve on at the tank. In the galley, turn
the switch to ‘ON’. The stove and oven burners are now ready to light. Use the lighter on
the front panel. There are also a piezo lighter and matches in the drawrer. The Captain
will cover lighting procedures at checkout.
Refrigerator/Freezer: The refrigerator/freezer run on both AC and DC power. When
connected to shore power be sure the AC circuit breaker is on. When not connected to
shore power the refrigerator circuit will “seek” DC power. There is a temperature control
knob and an on/off switch at the bottom of the refrigerator. Once the refrigerator has
reached the desired temperature, lower the temperature control to conserve battery power.
Central Vacuum System: The vacuum is mounted in the starboard settee in the salon. The
hose and attachments are also there. Pull the hose entirely out of the settee. Lift the
smaller flap on the top of the vacuum and insert the hose end to start the vacuum.
Remove the hose end from the vacuum to stop. Extra vacuum bags are provided if
needed. To replace the bag, remove the larger flap on the top of the vacuum. Dispose of
the full bag with your garbage at your next opportunity.
TENDER/DINGHY
“Latitude Adjustment” has an inflatable 10’6” Zodiac. It is mounted on the swim step
with a snap-davit. One person can launch and retrieve. The Captain should go over the
launch and retrieval process at checkout. A 3HP 2-stroke outboard and oars for the tender
are in the cockpit lazarette.
If using the outboard, do not attempt to mount the motor on the tender while still in the
raised position. The tender needs to be in the water before mounting the outboard.
The State registration for the tender will be found in the front of this manual.
REMEMBER: EVERYONE MUST WEAR A LIFE JACKET WHILE IN THE
TENDER. IT’S THE LAW!
