@Laz and @Than_Bogan it stands to reason solar is a great idea for ski boats given it's generally a summertime activity so I agree it would be worth pursuing. However I stand by my statement that electricity is not a great idea though. I believe we all must move away from coal, I certainly don't claim to be an expert on the subject but I know enough to understand that burning dirty coal is massively detrimental to the environment, there has to be a better way.
