Boats which are out to sea for more than a week at a time need facilities to make for a more comfortable work environment. Access to everyday electrical appliances help make this possible. It is much cheaper to equip the boat with
240V appliances than to buy lower voltage units generally designed for caravan and RV use.
I admit I don't know whether the OP's workboat has a 240Vc generator but I have done work on a fishing boat which did have this capability. 10 years ago it was common to have a 240V generator added when the boat was being built but I think that on more modern boats there is a trend towards using large capacity DC-AC inverters rather than a rotating alternator to produce the 240Vac.
