I am in the process of choosing my first boat and thinking about shoreline which are understand is 240v. I will have some electrical appliances but plan to be as light as possible on them. Especially when out cruising. I plan to be in marina only in winter months. I do not intend to use a washing machine, TV, or microwave whilst out of marina. Also I was thinking of perhaps having a 3 way fridge as well. My question is should I reject boats that lack 240v? Or should I consider having it installed as I realise it is probably costly? Any advice appreciated. Thanks.
