Salon (Main Cabin)

The salon (main cabin) is bright and cheerful with large portlights by day and direct ceiling lighting by night providing plenty of light.  (This picture does not do it justice).

A seating area with a removable table and settees can accommodate six or more adults comfortably.  This seating area can also be made up into an extra bed.

The galley is to port.  Doors to the private cabins and the main head are found fore and aft.

The electric and manual bilge pump intakes are located under the cabin sole at the foot of the companionway steps between the settee and the aft head.  This compartment should be totally dry and clean.   Check the operation of the pumps and make sure the intakes are clear.  Anything placed in the vicinity can interfere with the pumps' functioning.  This area should be kept free of lint or debris that could clog the pump.  Lift the float to test the pump.

(The manual bilge pump itself is located on the forward face of the port stern seat up in the cockpit.  It has a built-in handle.  Its intake (the black cube) can be seen beside the electric pump in the picture above.)

All the batteries are located under the aft end of the starboard salon settee.  The engine battery is the single battery on the starboard side.  The house batteries are the group of four interconnected batteries to port.

Warning: Be careful when storing items under seats not to drop anything onto the batteries. Charging and discharging batteries require air circulation and there is the danger of short circuiting if items are stowed carelessly.

Both the house and engine start batteries are charged from the engine alternator.  A battery isolator mounted on the engine firewall keeps the two systems separated and ensures there is always power to start the engine.  Be careful not to run the house batteries down beyond 12 volts on the voltmeter as this will damage them and the remaining power below 12 volts is minimal.  (Measure this voltage when there is no load on the batteries (switches are all off) and they have not been charged for a half-hour.  When lights and other loads are in use, the voltage measurements are not as meaningful.)

There is no battery selector switch.  The starter battery is always kept separate from the house batteries.

Cassiopeia has a large house battery bank for all normal cabin and navigation needs and connecting the relatively small starter battery would serve no useful purpose.  The house battery and the starter battery are not connected -- and cannot be connected. 

This guarantees that you will never accidentally run the starter battery down by leaving the switch in the wrong position and will always have a full battery to start the engine. 

(The starter and house batteries are both charged by the same alternator, but through an isolating circuit to keep them separate).

The main (emergency) battery switch is on the hull at the back of the nav station.

Useful Battery Tips

  • Be sure to turn off the furnace and fans, lights and instruments when they are not needed to conserve battery power unless connected to shore power or running the engine.

  • With conservative use of power, the batteries can easily last two days or more without a charge if they were fully charged to begin with.

  • By using tricks like loading the under-counter fridge with ice or frozen food and turning it off and by conserving power in other ways, the batteries can last even longer.

  • Running the engine, either in transit or at anchor will restore a partial charge.

  • If the voltage is above 12 volts while lights and fridges, etc. are turned OFF during the meter reading, (and the engine or battery charger are not charging the battery), the battery still has a safe charge.

  • Start and run the engine for an hour or so or plug into shore power if the battery voltage on the panel meter drops to 12 volts, measured when all loads including fridges and heater have been turned off for a while. 

  • Do not race the engine to charge.  1500 RPM or less is sufficient. (Motoring to a new destination at normal RPM (1800 to 2600 max) also charges batteries).

  • When leaving Cooper Boating base, the batteries are always fully charged.  Charging for periods of less than six hours will usually not return the batteries to full charge, but even an hour or two of charging or motoring brings the charge up a long way.


Along with the fridges, the lights and the instruments, the furnace and fans consume 12 volt electricity from the house batteries and all these loads can run down the batteries.

Be sure to monitor battery voltage when operating the heater, especially if the boat is not plugged in and the engine is not running.

The heater reset button is located under the starboard aft settee just outboard of the battery bank.

Two main service 125A and 120A fuses plus spares are located behind the seat back at the aft end of the starboard saloon settee. (right).  In the unlikely event that a fuse blows, ensure you have found and remedied the cause before installing a replacement fuse or the replacement will also blow immediately.

The “black box” brain for the Raymarine navigation system is in the same area.

There is storage space under the center seats of the starboard salon settee.

Galley pots and pans are stored under the settee nearest the galley.  This settee is hinged on the table side of the seat.  Lift the entire seat portion of the settee towards the salon table to access the storage.

Saloon Sleeping Setup

The saloon seating area can be made into a fourth double bed by removing and stowing the table (carefully, so as not to scratch it), installing the boards located under the starboard settee, then rearranging the seat cushions.

Navigation Station

The following items are located inside the nav station seat.

  • Flares:

    • 6 handheld comet type flares

    • 6 “shotgun” type flares

    • Flare gun
      They are in sealed plastic bags. 
      Please verify that they are still within 4 years of their date of manufacture.

  • Air horn and a spare air horn canister

  • Mini safety equipment kit for use in the dinghy.  Contains 15 m of buoyant line, whistle, flashlight . Check the contents and batteries before use.

  • Fire extinguisher. Check the pressure gauge

  • Wooden emergency plugs

  • Multi-meter and Various Manuals

Two tool kits and two winch handles are stored in the cabinet underneath the nav station table.

A Standard Horizon VHF radio (right) is located at the navigation table.  Remove and store the dust cover (shown installed) to access the controls and use the radio.

Channel 16 should be monitored while cruising.  Adjusting the squelch will eliminate distant chatter and noise while allowing local messages to be heard.

The weather channels should be checked for local conditions and alerts before setting out.

To use the remote RAM Mic (left) at the helm, the remote must be plugged in BEFORE turning this main radio on.  That way it will recognize and work with the remote mic.

The RAM mic is stored above the nav station when not in use.

The following items are stowed in the cabinet above the electrical panel and above  the nav station table. When not in use this equipment should immediately be returned to this cabinet.

  • Binoculars 

  • Flashlight

  • 2 winch handles (May also be in toolbox cupboard)

  • Remote RAM Mic

  • Various official CHS publications and cruising guides

  • Anchor windlass control (right)

  • Various manuals relating to the boat and its equipment


The main battery (emergency) switch (circuit breaker) is located on the hull liner under the navigation station. (left)

The battery charger (right) is located underneath the navigation station in the bulkhead between the navigation station and the salon dining area.

When plugged in to shore power, the lights will indicate ready, charging and the rate of charge in amps. (see manual)

A fan on the charger may run periodically, especially when first plugging into shore power after running on the batteries or when using a lot of lights.  The charger only operates when connected to shore power.


Cassiopeia is equipped with an Espar diesel furnace which maintains all cabins at comfortable temperatures even in freezing weather. This furnace is very economical on fuel and does not consume too much battery if used judiciously.

Together with radar, the fully enclosed cockpit, and roller furling with all lines led to the cockpit, this thermostatically controlled furnace makes Cassiopeia a comfortable all-weather boat, even in a West Coast winter.

The On/Off switch and thermostat for the diesel furnace is located above the navigation station. (right)

This is the primary control for the furnace (on/off) and sets the maximum air temperature for the cabins and heads.  In addition, some cabins and the heads have their own heater fan switches to allow for adjusting the heat locally.

The furnace and fans use battery power, so turning the furnace down at night and not heating cabins or heads where heat is not needed will conserve both battery power and fuel.

Note: The furnace shares the diesel fuel tank with the engine, but draws its fuel from a tap higher up on the diesel tank so that the furnace will not accidentally run the engine out of fuel.  Keep the fuel diesel tank filled above one half to ensure ample supply for both.

The diesel tank is always full at the beginning of the charter, so fuel should not be a problem, though.  The tank holds enough diesel for over 50 hours of running on the engine and many more hours of Espar use.


The stereo is located at the nav station.  There are four speakers, two in the main cabin, and two in the cockpit.

Keys for locking the dinghy, outboard any other lock for the boat should be in the chart table. Please leave them there when you’re finished.

Charts and Books

Charts are located under the lift-up top on the nav table.  

Books are stored in the cabinets above the navigation station.

Please make sure all the charts and books you need are present.

See the Reference section for a list of publications and navigation equipment that should be on board.

Also, please erase your chart work when your charter is over.

12V Electrical

The battery cut-off switch is on the outer wall under the navigation station.

The batteries are under the aft salon settee near the nav station.

[is this anything]

120V AC System

The 30-amp shore power cord and pigtail are stowed in the port stern locker.  The 15-amp adapter ("pigtail") is attached with a small cable so it won’t get lost.

When handling the cords, be careful not to drop the plug end or the prongs will get bent, making the cord difficult or impossible to plug in.

Please note the location of the reversed polarity light on the 120V electrical panel, and check it when you plug the boat in to shore power.  If the reverse polarity light  comes on, alert the marina management and select another shore outlet to plug into.

Do NOT operate on shore power if the reverse polarity light is on.  Incorrect polarity creates a dangerous shock hazard on board.

Also note that the AC switches/breakers are RED when on (Up) and GREEN when off (Down).  Green, in this case, indicates safe because the circuit is OFF.


Please look through the cupboards and drawers to make sure you have enough dishes, pots and pans, and utensils for everyone aboard. The boat is normally set up for 8 people.

There are two fridges: a smaller front-loading fridge with freezer compartment under the galley sink and a larger top-loading fridge/freezer beside the stove.

Each fridge has a thermostat inside the fridge. Turn the knob off or set it on low if the batteries are not being charged by the engine or by shore power. The front-loading fridge has a thermostat control in the top of the fridge by the freezer unit. Clockwise is colder.

The fridges use a considerable amount of battery power when the engine is not running.  The batteries can handle the load, but the length of time that the batteries maintain a useable charge will be less if both fridges are running.

Turning off the refrigeration when sailing or at anchor will extend the length of time that the batteries remain charged considerably. Buying ice at marinas to put at the bottom of the counter unit can be a useful strategy to keep food cool and extend time between battery charges.

The top-loading fridge/freezer can be a fridge or a freezer depending on the setting.  The mark near the knob is a setting that gives refrigerator temperatures up top, with colder spots on the bottom and near the cooling plate.

The bottom of the top-loading fridge/freezer is quite a bit cooler than the top and, even if it is set for use as a refrigerator, may freeze produce placed at the bottom, especially if the unit is full of food or things are contacting the cooling plate.

Smart sailors often buy pre-frozen food and ice to reduce the amount of cooling energy required from the boat's systems.

The stove and oven unit is on gimbals. It can be locked in place or allowed to swing in order to stay level when tacking.  Screw-on fiddles (in the cupboard) can be used to hold pots or kettles in place in rough weather.

The stove and oven operate on propane which comes from a bottle stored in the locker under the aft port cockpit seat.  See below.

A solenoid switch to cut off the propane gas (LPG) for the stove is located on the side of the cabinet behind the stove next to the 110V outlet.

The LPG switch should be turned off at all times when the stove is not actually in use.  

Be very certain to turn off burners and the switch as soon as cooking is done.  Do not leave the stove unsupervised.  Propane leaks or fires on a boat are life-threatening.

Propane is heavier than air and can accumulate in the cabin if a leak occurs or a stove or oven burner is turned on -- accidentally or otherwise -- and does not light.  If enough propane accumulates in the bilges and cabin over time, an explosion could result, or people could be smothered.

The boat has a carbon monoxide detector installed below the cabin sole.  As well as warming of carbon monoxide, this detector should also detect propane and give warning of any leaks.

Propane is stored in two bottles in separate lockers under the stern seat. These lockers are vented to the outside of the boat for safety.

The bottle on the port side is for the stove and the starboard one is for the barbeque.  They can be interchanged should one run out.  This should not happen, as the bottles are always full at the beginning of a charter.

Please see further instructions for the propane stove in the Instructions section.

A 120 Volt  outlet is located beside the LPG solenoid switch.  This outlet is for use with a coffee maker, toaster etc. (this equipment is not provided with your yacht).  This outlet only provides power if you are connected to shore power.

Heads (Washrooms with Showers)

There are two heads on Cassiopeia, one forward in the captain’s cabin and the other is accessed from the saloon.

IMPORTANT: Do not put anything down the toilet that you have not digested, with the exception of small amounts of toilet paper.  To do so may immediately block the head and require some unpleasant work to unclog it.

See the Instructions and Reference section for complete instructions on the use of the head.

All waste from toilets goes directly into the holding tanks. There are no Y-valves.  Each head has its own holding tank.

The holding tanks are emptied using a pump out station through the deck fittings or via gravity feed by opening the thru-hull fittings.  The location of these seacocks is shown below under the description for each head.

Waste tank level indicators are unreliable at the best of times and therefore the waste tank level gauges are not connected as they would give a false sense of confidence or unnecessary concern.  Since there are no waste level indicators, please use a pump-out station or empty when legal to do so at sea whenever possible, no matter how full or empty the tank is, and be sure to monitor your use of the holding tanks carefully.  See how further down.

Aft Head

(For the forward Head, see Forward Cabin)

The valve for switching between the two domestic water tanks is located under the basin.  

If the water pump starts running non-stop and no water tap is on, simply turn this valve 90 degrees to change tanks. 

Rotating the handle (right) switches from the forward to aft fresh water tank.

If one tank is run empty, after switching tanks the automatic pump may run until the water comes through the system. Opening a tap for a moment will let air out and help prime the system.

The domestic water pump and in-line filter are also located underneath this sink (right)

The sea cock for the head sink drain is here, too at the very back of the cabinet, against the side of the hull. 

Shower sump discharge and head sink discharge sea cocks. (Both are open)

The head intake seacock (right) is located under the plastic seat in the shower, along with the head discharge valve (left) .
Head discharge seacock and intake seacock

The head discharge valve should be closed at appropriate times, ie.  in marinas and in anchorages, thereby directing waste into the holding tank.

The level in the black water holding tank (right) can be monitored by doing a visual check.

Simply open the rectangular plastic access panel located above the plastic shower and you will see the holding tank.  Tap on it to get a sense of how full it is.

The circular access panel above the shower bench provides access to the holding tank discharge hoses (for service personnel only).

The basin tap is used for the shower.

Shower water collects on the floor and must be pumped out by pressing a black rubber momentary switch on the basin cabinet. (left).  Push and hold until the drain gurgles and sucks air.

Showers can use a lot of water.
Be careful not to use all your fresh water.

Note: The shower sump switch on the 12V electrical panel must also be turned on for the pump to function. 

If the shower sump pump makes noise but the shower floor drain is not pumping out, check the inline filter. The filter cover simply unscrews by hand so that the wire mesh filter can be cleaned and reinstalled. 

The discharge seacock for the shower sump is accessed under the head basin.  It is located far in the back on the side of the hull next to the head sink discharge.

If the shower sump pump makes noise but the shower floor drain is not pumping out, check the inline filter. The filter cover simply unscrews by hand so that the wire mesh filter can be cleaned and carefully reinstalled.

The furnace outlet and control switch in the aft head are shown at right

A 120V outlet is located in the forward cabinet above the head. 

This outlet can only be used when connected to shore power.

Engine Compartment

The engine is accessed by lifting up the upper section of the  companionway steps.  If necessary, access can also be gained through the access panels located behind the cabin doors in each of the aft cabins.

To access the front of the engine, simply lift the lower stairway section up and out of the groove that holds it and set it aside.  More information about checking and operating the engine
