If you replace light bulbs with 120V ones of the same wattage then you risk overloading the wiring etc. of the lighting circuits. Have an electrician check the wire size and current ratings of the switches and determine what maximum current the lighting circuits can handle safely. This will allow you to work out how many 120V light bulbs (and their wattage) can be used. If you replace the 220V light bulbs with 120V ones of half the wattage of the originals you will be safe.
Any motors (such as the compressor motor on your fridge) will most likely burn out due to the lower voltage. Don't attempt to run any 220V motors at 120V.
It is possible to connect another 120V phase instead of the neutral which will give you 208V. This will most likely allow the motors to run without getting excessively hot and your light bulbs and heaters will work well too. The 60Hz will make the motors run faster but this shouldn't be an issue.
This assumes that two phases are available from the shore power and that the shore power earthing arrangement is suitable (star connected transformer with star point earthed).
I am pretty sure all the lights in the boat is operating by DC, it should be non issue. As other suggested, most of the appliance or motor may be dual voltage. Remember, Beneteau build boat for international market.
But anyway, I will contact Beneteau directly to see if I can get some help from them, or at least send me the schematic diagram and their specs for me to sort out.
I read, think, and act independently; I don't come here to win a popular contest, nor I am here for free sex. I come here to learn, be challenged and be inspired in the art of safe off-shore passage. I am NOT afraid of dying in the sea, but I am afraid of dying in a nursing home and burdening those who I love.
I am old school; doing the right even when no one is watching is important to me.
