Hi everyone, ive had my narrowboat for about four months and have been happily living off the leisure batteries. However I now have the opportunity to access shorepower and would like to have access to a few luxuries from time to time (like tv, or the ability to charge my laptop onboard). I have no idea what to do though. My boat has no power sockets whatsoever. As far as I know the only things that run off 12v are the lights and water pumps (shower, oven, fridge etc works off gas). there is no external socket for shorepower. I assume that in order to access shorepower I need quite a bit of work done on the boat. Can anyone explain - slowly - what I need to do? Many thanks for reading.

My little boat is a 30 footer. She has no inverter/hook-up to mains, and I would like to toddle off soon and do some exploring She has.a new starter battery, and a bank of 3 leisure batteries which have been left for the best part of year, and I am about to accept that they have had it, (have topped up cells, put bataid tabs in - yes, have been told not to bother). Batteries charge when engine running, and provide some power for a short time afterwards, but as predicted, then fail. Have had on slow charge and they read about 10.1 v after boat has been left for a couple of days (it was 4!). Someone said they wondered if I needed three batteries for such a small boat, so my question is - how do you calculate how many batteries you need, and of what capacity please? The power is needed for the following:- Lights Computer Water pump Charging mobile phone Hairdryer (not daily) I have a 12v TV on boat - not currently working - but would liike to include it in my list of power needs for the future. Any advice/guidance much appreciated.
