Hi, we are just in the process of having a 57' (going to be a liveaboard) narrowboat built and took the time to visit the IWA at Redhill today. We were discussing the possible 'electric' permutations with many of the vendors there, of which many stated '24volts is the way to go' - that is apart from the guys at the Vetus engine stand who said they have never done a 24v alternator ever, for a 'narrowboat' - this worried us slightly as we have already budgeted for a 42hp vetus engine. Now don't get me wrong, they did say that they can 'do' a 24volt alternator just that they had not done one before 'as most were 12v). So, is this the case, are we going the wrong way by thinking about a 24volt system ?, how many narrowboats have 24volt (I appreciate that most have 12v) - so we are asking for advice here from people who know what's best - so for a new build do we go with 12v or 24v.?
Thanks in advance for your help.
