I think that trying to use wind on a canal boat would be a disappointing exercise. Wouldn’t the wind be blocked much of the time?

On board my 30 foot sailboat I go with a three legged stool approach to charging my 48 volt battery bank. I have solar panels, wind generator and a Honda 2000 eu gas generator. Actually it's a four legged stool because I can also plug in to dockside power too. My wind generator is a 48 volt Marine Air X 400 watt unit. It is about $800 and works well to keep things charged up in combination with the solar panels. I don't think you need a big 2000 watt wind generator for your application. But, you should check out the winds in your cruising grounds. You might be better off with just solar panels and a generator for your charging needs. I may be wrong but, I don't think canals will have enough wind energy to make a wind generator a viable charging option.

Just a thought but would a wind generator be appropriate? 24 hour a day charging. The heaver the wind the better the charging. MIght have to have some sort of mount so it could be raised and lowered for bridges etc. And I have no idea what the winds would be like. A 2kw 48 volt system is about $2,000 US and 3 m in diameter. About the size of a dinghy sail so not much healing moment (depending on the mast height).
On the other hand wind generators can be noisy ( good design can prevent this ), mechanically complex and there are air draught issues.

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?
