  GENERATOR
Mariela Paola Ben 52 scheiber (1)
Mariela Paola Ben 52 Scheiber (2)
Mariela Paola Ben 52 scheiber (5)
Mariela Paola Ben 52 scheiber (3)
 

STARTING THE GENERATOR

  • Make sure all your breakers are OFF 
  • Go to the side compartment in the saloon (no. 2 on the boat layout
  • First slide the red safety tab down, then press the top of the switch in (the switch all the way to the right on the picture, the upper switch)
  • Press the generator switch UP shortly. You should hear a click from the generator unit. (the switch all the way to the right, the lower switch)
  • Go to the main panel to turn the generator on on the Scheiber unit (display all the way to the right, second from the top):
    • Picture 1 above: Select the blue plug on the touch screen 
    • Picture 2 above: Select any gray icon GE
    • Picture 3 above: Click the START on the touch screen. It will take at least about 20 seconds for the generator to start. The indicator will show the Voltage.
    • Go back to the screen before (Pic 2) and select what you'd like to use the generated power for: the sockets icon on the left, or the AirCon icon in the middle.
    • Picture 4 above: to switch between using the shore or generator as a power source, select the middle icon first before switching over to one of them.
  • Be aware of the generator load when using.

SHUTTING DOWN THE GENERATOR

  • Turn off the equipment you were using
  • Turn off the generator on the main panel
  • Go back to the generator battery switch under the seat and flick the upper switch upwards. 
 

NEVER RUN THE GENERATOR WHILE UNDER WAY!

Make sure not to overload your generator, sometimes you can only run one thing at a time. (like only your A/C, or only your water maker) Using any electrical appliance at the same time as A/C can trip the generator breaker. 
 

GENERATOR TRIP SWITCHES AND INTAKE FILTER

The generator itself is in the stern of the yacht. If you have overloaded your generator, it will trip out. In that case turn everything off that was using the electricity generated from it, turn off the generator, and start everything from the beginning.

If the intake filter becomes blocked (by seaweed or other debris), it can cause the generator to overheat and stop.

 SIDE COMPARTMENT
Beneteau 52 main breakers-1
 
It contains (from left to right): 
INVERTER SWITCH - This allows some of the 220V outlets on board to run off the domestic batteries, without Shore Power or the Generator. Note that this causes a considerable drain on the batteries.
ENGINE and DOMESTIC BATTERY MAIN SWITCH - Needs to be on to use 12V electrical power on board and to turn the engine on.
WINDLASS TRIP SWITCH - In case the windlass is overloaded, this trip switch will shut down. 
GENERATOR POWER SWITCH - see above for Generator start and usage. 
 
  BATTERIES
 
The 12V domestic batteries panel and its switch is in different positions for numerous types of boats.On this boat the main domestic batteries switch is under the seating in the middle of the boat (no 2 on the layout picture), and the switches are on the main panel (no. 1). The domestic batteries charge the yachts lights, fans, fridge and freezer units, water, heads and shower pressure and drains, navigational and sailing instruments, as well as the radio and VHF.
 
On this yacht the water maker can also use the 12V electricity, as well as the inverter. 
 
 
Please be aware that batteries are best recharged by engines, then the generator and shore power source, and sometimes by the solar panels. We recommend recharging the batteries with engines at least twice a day for a few hours. To do that while not underway, enter neutral RPM's by pressing the red button on the throttle, and push the throttle forward while it is pressed. Go up to 2000 revs and then back to 1500 to charge the batteries.
 
We recommend turning off unnecessary equipment during the night, especially drawing your attention to underwater lights, fridge, freezer and inverter. 
 
 
 UNDER THE CUSHION
Mariela Paola Ben 52 trip switches under cushion
 
Under the cushion in the seat in the saloon, (no. 3 on the boat layout picture) is a compartment. It contains trip switches for (from left to right): Platform,  Electrical Winches, Watermaker, Inverter
 
 HEADS
 
This boat has 5 heads, and 5 holding tanks with 5 holding tank valves to empty them (marked no. 4 on the boat layout picture). The holding tank valves are all under the floorboards inside the boat, and under the bed in the skipper's cabin. 
 

SHOWER DRAIN

Shower drain on this boat is automatic, so the shower drain pump will automatically turn on to pump out the water while you are showering. There is an option, however, to press the shower drain button as well in case the automatic option fails. 
The forward cabins on this boat have a gravitational disposal of the bathroom sinks, and in starboard bathrooms you will notice that everything from the sink flows into the shower drain first, so the shower drain pump will turn on every time you are using the sink, too. 
 

TOILETS FLUSHING BUTTON

There are 2 flushing switches next to every toilet. The lower one can be pushed to the left and right. Pushing it to the right will drain the bowl, while pushing it to the left will rinse the bowl with clean (salt) water.
The upper button is the flushing button, pressing this will drain and rinse the bowl at the same time. We recommend topping up the bowl with clean water fully and draining it after every flushing, to avoid the return of unclean water to the toilet or unpleasant odours, due to the tanks being gravitational. 
There is an additional button below the flushing buttons - that will enable you to use fresh water from your tanks to flush rather than salt water. Due to this tank having only 1 water tank, it is not something we would recommend. 
Be careful to never put any paper or similar in the toilet! Sunsail and The Moorings reserve the right to charge a fee for additional cleaning and for each toilet blocked if deemed required.
 

HOLDING TANKS

The holding tanks on this boat are gravitational, meaning you can empty them simply by opening the holding tank valve. We recommend doing so daily, at least 3 miles offshore. Please remember to CLOSE the holding tanks while you are on an anchorage, mooring buoy field, or in a town or marina. Also, remember to empty all your holding tanks before coming back to the base. When the valve is lined up with the pipe (parallel), the valve is open. Turn it so it is crossing the pipe to make sure the valve is closed.

 DIESEL TANKS
 
This boat has 2 diesel tanks, each 200 litres capacity. Please make sure you understand where the diesel top up inlets are above deck - at the stern below the flooring, one next to each helm, and DO NOT put anything but diesel in them. They have a yellow, orange, or red stripe visible once opened. 
 
To change which diesel tank is in use, go to the Diesel tank switch levers (no. 5 on the layout picture) in the starboard stern cabin. When both switches are pushed in, the port tank is in use. To switch over to stbd tank, both levers need to be pulled out. It is a good idea to switch them over after 3 days if you have been continuously motoring. Check the tank levels on the display on the main panel.

 AIR CONDITIONING
 
This boat has 4 Air Conditioning Units, and 4 Air Conditioning panels, marked with a star on the boat layout picture: 
  • 1 unit for both stern cabins, the control display is in the starboard cabin on the wall 
  • 1 unit for the saloon, the control display is on the main panel
  • 1 unit for both forward cabins, the control display is in the port cabin on the wall, knee-level
  • 1 unit in the skipper's cabin, the control display is in the cabin
 

CONTROL PANEL

Make sure you have either the shore power connected or the generator connected through the main panel ( AirCon icon is the second one on the first image. More details on generator connection and usage see on this page above). Remember you cannot use the A/C while under way. 
  • On the A/C panel press the POWER button to turn A/C on or off.
  • On MODE button toggle between cool / heat /dehumidify.
  • Use the arrows UP / DOWN to adjust the temperature. We don't recommend going below 20 degrees Celsius. 
  • On FAN button adjust the speed of fans of the AirCon unit. Don't leave this setting on too low if you are on a low temperature as the unit may freeze over.  

KEEP YOUR DOORS AND HATCHES CLOSED!!

Please be aware that you need to close your hatches and doors to allow the Air Conditioning Units to operate properly.  If your unit stops cooling, but the fans are operating, it means the unit froze over due to its settings. Give it about half an hour to defrost and try again.
 

BLEED VALVES

If your A/C is counting down or showing HIP, it means the system has too high pressure needs bleeding. The valves to do that are marked with a number 6 on the boat layout: for the saloon and stern A/C units it is in the engine compartment, and for the forward and skipper cabin units it is under the floorboards in front of the forward cabins. Best is to give us a call to do it for you. 
If your A/C is showing letters LOP, it means there is too low electrical current. Try changing the cables, or give us a call

  WATER MAKER
Mary Lou Ben 52 water maker
 
Most of our vessels need a generator to run the watermaker, however this unit can run also on 12 V, just much slower. On this yacht the watermaker unit is under the skipper seat (no. 7 on the layout picture)
 
DO NOT USE YOUR WATERMAKER WHILE UNDER WAY!
 
The watermakers all have flushing sequences, we make sure to do that on every yacht turnaround. Please never use water makers in less than 2 metres of water, otherwise your watermaker filters will need to be exchanged. 
 

USING THE WATER MAKER

  • Make sure you are not under way and not in less than 2 m of water
  • Check that your water pump is ON.
  • Turn ON your generator if you need
  • Turn the blue switch on the left side to either 12V or 230V, depending on whether you are using only batteries or the generator
  • Wait a minute for the system to start
  • Turn the pressure valve clockwise till the pressure regulator is in the green zone. Be aware you may need to tweak the valve carefully for a bit. If the pressure reaches too much into red, it will automatically stop producing water and turn the water maker off. This is also one of the most common reasons people think the unit is not operating properly, so make sure to keep an eye on the pressure. 
  • Wait till the light goes green for GOOD QUALITY water.
  • Normal production of the water is between 40 and 60 litres per hour. Track your water levels on your main panel, and turn off the water maker when there is enough water in your water tank. Overfilling your water tanks can also cause breakages of the tanks themselves. 
  • Turn the valve counter clockwise to turn the water pressure off.
  • Wait till your water pump stops working. 
  • Turn the blue switch back to the neutral position.  
  • Turn OFF your generator if you were using it.
  FRESH WATER CHANGE-OVER VALVES
 
This boat only has 1 water tank,  240l capacity. Make sure to keep an eye on your water levels during your charter, and plan your route with refilling stations or good places to use the water maker. Your water top up inlet will have a blue rim around it, it is on the port side around the middle of the boat, and is not to be confused with other inlets above deck!  
   STOVE USAGE
 
Stove uses gas bottles stored above deck (no. 8 on the boat layout picture). One bottle in use is always connected to the system, and there is a second full one to exchange if needed. Always check the stove is operating to your satisfaction during the yacht briefing, and you have the spare gas bottle on board. 
 

USING THE STOVE

  • Open the gas bottle counterclockwise in the locker.
  • Check the yellow solenoid valve under the sink is open.
  • Turn the needed burner on. In case the installed igniter isn't working, there are some matches and a lighter in the drawer for that purpose. Sometimes it may take a couple of seconds for the gas to travel to the system, so keep the button pressed for a couple of seconds. 
  • Make sure you close the gas bottles when you are not cooking. 
 
 PLATFORM
 
This boat has an electric platform. To use it, the main breaker under the cushion in the saloon (no. 3 on the layout picture)  needs to be in the ON position. If for some reason the platform isn't working, this is the first place to check. 
 
The UP / DOWN buttons are next to the port helm above deck (no. 9 on the layout picture). Please make sure to remove the safety pin from the platform before lowering and to return it after the platform is in the upward position. 
 
 
 BOW THRUSTER
 
Bow Thruster control unit is marked with no. 10 on the boat layout picture, it is next to the starboard helm.
 
To use the bow thruster, press the two ON buttons simultaneously. Then simply use the port / starboard arrows depending which way you want your bow to move.
 
Remember to only use the bow thruster in maximum 5 seconds bursts. Otherwise it may burn out. 
 
To turn it off, just press the OFF button.

 UNDER THE BACK CUSHION
Mary Lou Ben 52 shore and ac trip
 
Removing the backrest cushion in the saloon (marked with no. 11 on the boat layout picture) reveals the Trip Switches for all Air Conditioning units (to the left) and the Shore power (to the right). In case your A/C stops working or you lose shore power electricity, check here to see all switches are in an upward position.
 
To use shore power electricity: 
  • Plug in the shore power cable (double check the connection wasn't lost in the port locker) 
  • Check to see if there is power coming from the shore source (sometimes you will need a marinero's help, or there is a switch on the power box on the dock)
  • Go to the main panel Scheiber display and double check it is set to shore power (and not on generator source)
 
See the A/C section to see more about A/C usage on this boat. 
 
 
 ABOVE DECK
Ben 52 Mary Lou helm
 
This boat has twin rudders, and its depth is set below keel. 
 
The navigational equipment is B&G, and at the helm you can see the MFD - multi functional display with the chart plotter, windex, and audio and autopilot functions. Next to it is a little panel just for the autohelm. On the side will be a bow thruster control panel, the throttle, the anchor chain counter and control, and the engine control panel. The boat also has a steering lock at both helms.
 
There are two electrical winches above deck, and all the lines are marked on the jammers. Make sure to go through the inventory list in your check in booklet before sailing out to check you've got everything you need in your lockers. 
 
This boat has a self-tacking jib.

 

MULTI FUNCTIONAL DISPLAY

There is one MFD next to each helm. The starboard one is the master screen. Make sure your NAVIGATIONAL EQUIPMENT and ELECTRONICS is ON on the 12V main panel in order to use it. 
Choose the CHART segment to open charts. The SAIL STEER segment will show you the data for wind speed and direction. To view both on one screen you can customize your view on the right side of the screen. 
On the left side will be AUTOPILOT and AUDIO buttons, too. Mind that the touch screen is quite sensitive so we don't recommend relying on those while under way. 

CHARTS

Charts are fairly easy to use with the touch screen. You can build your routes simply by long-clicking the part of the chart needed and go to BUILD ROUTE. Select the CLEAR CURSOR on the bottom right to always re-centre your charts to your boat. 
To change the view between North Up or Head Up, select the three dashes symbol on the charts, then find the MORE OPTIONS, and change the ORIENTATION. 

AUTOPILOT

Try to use the separate panel for autopilot engagement. Once you click the AUTO on the panel, the boat will be set on autopilot and hold the course. Remember to always keep a lookout even when on autopilot. Clicking the - or + 1 will adjust the direction 1 degree to port or starboard, while -10 and +10 will do so by 10 degrees. The screen will also show that your autopilot is active. To disengage the autopilot, click STBY. 
 

DECK SHOWER

Marked with 8a on the boat layout picture, there is a deck shower. To use it, make sure your water pressure is on on the main panel. You need to switch on the valve to use it, and you can also adjust the water temperature. 
If it seems the deck shower isn't working, try getting the whole hose out, it could just be tangled in the locker. 
After you are done with deck shower usage, please close the valve and then empty the pressure from the hose to prevent damaging the hose under pressure.

LOCKER UNDER THE PORT SEAT

Marked with 10A on the boat layout picture is the main shore power trip switch. In case you don't have shore power or A/C on board, check here to see all the switches are in the upright position. Our advice is to also check on shore to see the town quay or marina have supplied your boat with electrical power, or if there is a switch you haven't flicked. Additionaly, check behind the back cushion for switches, and on your Scheiber panel inside the boat before calling the base for support. 
 

PORT SIDE PANEL

Marked with number 9 on the boat layout picture is a little panel at knee-height with platform usage buttons and outside lights switches (make sure LIGHTING switch is on on the 12V main panel as well).
