Re: [Electric Boats] solar canal rambling

I would recommend having a Honda 2000 eu (or similar) generator onboard to at least bulk charge the batteries. It is a great backup for when solar falls short of the boats needs. Or you really don't want to spend time at a Marina plugged in. It is a workhorse. It is is small,  lightweight and relatively quiet. I use it onboard to bulk charge the battery bank and power a small ice maker at the same time. I do like a nice "boat drink" at anchor sometimes. <g> Only use it when I need to but, it is a nice backup to have onboard,

theres an extensive canal network here in UK. I've often thought it would be great to do a leuisurely trip . stopping for a while to explore an area whilst charging batteries from solar panels and then moving on. The problem would seem to be that if charging over say a week or two that the batteries would most of the time be only partly charged . Is this a fast way to kill lead acid batteries or would a slow charge resist sulphation?
I'm guessing that a better regime would be to just do a few miles per day using a small depth of charge. Any comments?
