5250 divided by the weight of golf cart batteries (66 lbs) means I would need 80 batteries to get the range I have with diesel.
True enough. But, if one uses the engine in their sailboat primarily just to get n and out of the harbor, then range becomes much less problematic; even more so if regenerative sailing is added to the analysis. And remember, we are talking about sailboats here.
