The fuel deposit of your yacht consists of two tanks installed in the engine room, close to the fore bulkhead, reinforced internally and certified and tested by RINA.

Inside the tank there are some antiflapping bulkheads (diaphragms) in order to avoid an excessive swashing of fuel due to the wave motion of the sea.

Hermetically sealed inspection flanges are bolted on the tank, through which all fuel delivery and return passages occur.
The refuel plug, through which the tank is filled by gravity, and closed by a screw plug, is located on the starboard side.
The fuel intake of the yacht is equipped with a flow switch having the function to prevent undesired leaks of fuel from the plug and from the vent which may stain the bridge and pollute the surrounding waters.
The fuel bleeding from the intake ducts is collected by a tank with suitable capacity which, on its turn, will be drained automatically into the fuel tank through the relevant return duct.

While boarding, the fuel flow produces a lot of foam; if it comes out, you might think the tank is full.
Therefore, it is good to wait for a few minutes and then top up, in order to be sure that the tank has been completely filled.
The vent piping, with flame-breaking net, connects the upper part of the tank to the wind-proof discharge located on the yacht’s starboard side.

NOTE

We recommend filling the tank some hours before departure; in this way, the impurities and water in the fuel will decant on the tank bottom as they are both heavier than fuel.

It is necessary to regularly drain the condensate water from the tank and the separator filters.

The particular shape and arrangement of the tank eases settlement of possible impurities or water which may be present in the fuel; it is advisable to carry out tank drain, by means of the special air valve, a few hours after refuel, and possibly while the yacht is stopped.

It is also advisable to connect the bleeding valves delivery to a hose, convoying the liquid into a bucket in order to avoid collecting flammable fuel in the bilge, thus preventing the formation of noxious exhalations.

DANGER

Because of the high temperature in the engine room, oil or fuel leaks can evaporate and create a serious risk of fire.
Fuel leaks can cause fire. Regularly check the integrity of the system.

ENVIRONMENT

A fuel leak can generate fire and explosion hazard.
Fuel cannot be stowed inside the garage.

CAUTION

The inlet plug carries the indication “DIESEL” to avoid accidental input of different fuels.
To avoid damage to the system and tanks, we recommend refuel by gravity and not by pressure.

The fuel level, shown on the helm position digital display, is detected by the electronic level switch installed near the tank itself.
In addition, there is a visual fuel level in the engine room on both tanks.
