There seem to be people who say "I'm electric its fantastic" it cost me a penny a mile, solar its free etc etc, however just wait until in a few years your batteries are toast and need replacement all that free energy will not be free after all. That to you think the tax man has not got this on his radar just waiting to get to a certain point of no return and then bang taxed up to the hilt.
Also I bet electric boats dont have that little gen set (5kva I bet to) tucked away that get used every other day to "so much for clean boating. Or do they sit in a marina 24x7 like I see so many boats. I have had mine since April last year and up to date done 600+ hrs of cruising that to mid Oct out of UK for 2 months then stuck because of floods and Foxton flight being closed. I bet my carbon foot print is lower then a house owner running a car heating etc so boat on Diesel is not so bad after all.
