placed as close to the batteries as possible and connected to them with cables sized according to its power.
A 12/220V converter on board is a real plus. It permits the use of everyday devices on board without worrying about their power supply. It must though, be used sparingly. For a permanent installation, such as a computer at the chart table for example, seek to use a 12V power supply instead of connecting a converter. In contrast for a device that can be used only occasionally, such as the hand tools or a hair dryer, a converter is fine. Care must be taken to choose a model that can support consumption (wattage) always look to a model over the consumption declared.
