Dufour 365

The only head on this vessel is equipped with a sewage holding tank. Under the head sink there is a large black “Y” valve to bypass the tank. In one position, sewage is discharged directly into the sea; in the other, sewage is discharged into the sewage tank first and then into the sea. To hold sewage inside the tank, the gate valve must be closed. This is the largest of all the gate valves located under the sink.

Windlass Switch. This is located in the chart area, behind the electric panel. To see and reach the switch, you need to open the panel to the right of the chart table seat by turning it downwards.

Engine Dashboard Layout: the dash is the electronic model by Volvo. It has four buttons: the one at the top left turns the dash and power supply on. The one at the top right cranks the engine; the button at the bottom right shuts the engine off, and the one at the bottom left turns the dash light on.

The switches to swap between the two water tanks are located in the dinette beneath the sofa, where the boiler is located too.

The gas switch is located in the compartment under the galley.

The GPS is a Navman tracker XXXXX. On turning it on, the display shows automatic satellite search. As soon as the device finds a connection, the display automatically shows an electronic map. The main windows are the electronic map and the current coordinates of the boat. When viewing the electronic map, the display shows further information at top: speed of the boat over ground (sog - speed over ground), the boat’s course over ground (cog - course over ground) and the coordinates of the cursor, which are not the coordinates of the boat. For the information on the coordinates of the boat, you must in fact follow the path DISPLAY/SATELLITE.

 

Dufour 455 Emotion

Engine dashboard – cranking the engine. To crank the engine you must first turn the dash on. This is done by pushing down the black lever located to the right of the dash. You then press the start button, located beneath the lever. To stop the engine, you pull the lever up.

 

Dufour 455 Passion

Behind the panel to the right of the chart table, there is the thermal-magnetic circuit breaker for the windlass.

In the aft starboard cabin there are the battery switches.

On Passion, the same cabin contains the thermal-magnetic circuit breaker for the deckhouse winch; this is found by opening the first panel located above the engine panel. Very important: great attention must be paid when hoisting the mainsail with the electric winch, because the jamming of a slide can tear the mainsail. Equally important: do not haul the mainsail excessively.

Engine Dashboard Layout: the dash is the electronic model by Volvo. It has four buttons: the one at the top left turns the dash and power supply on. The one at the top right starts the engine; the button at the bottom right shuts the engine off, and the one at the bottom left turns the dash light on.

The switches to swap between the two water tanks are located in the dinette beneath the sofa, where also the boiler is.

Under the aft head sink there is a large black “Y” valve to bypass the tank. In one position, sewage is discharged directly into the sea; in the other, sewage is discharged into the sewage tank. To hold sewage inside the tank, the gate valve must be closed. This is the largest of all the gate valves located under the sink.

 

Grand Soleil 40 Philine e Oscar

VERY IMPORTANT: great attention must be paid not to accidentally pull the black lever located in the extreme aft locker on the engine ignition side. Because this lever operates a shut-off valve for the fuel tank, its accidental closing would in fact soon stop the engine.

VERY IMPORTANT: the battery switch positioned under the chart table works as follows:

Position 1: battery 1 is on and battery 2 is off. Battery 1 powers BOTH engine and electrical accessories.

Position 2: battery 2 is on and battery 1 is off. Battery 2 powers BOTH engine and electrical accessories.

Position 'Both': both battery 1 and battery 2 work together, giving power to the engine and the electrical accessories. If accessories such as fridges, lights and autopilot are used all at once with the battery switch in this position, both the batteries may discharge at the same time and would no longer be able to crank the engine.

The only windlass switch is the one on the electrical panel.

The switches for the water tanks are located in the bilge, under the opening floor plate at the foot of the ladder to the saloon. In the same location, there are also two gate valves for the bilge pump. In fact, the same pump works as both a shower drain for the aft head, and as the main bilge pump.

Care must be taken in opening only one gate valve at a time: if liquids need to be sucked up from the main bilge, you must open the corresponding gate valve and shut the aft head shower drain gate valve; the opposite must be done if you want to turn on the shower drain in the aft head. The bow head has an independent pump.
