I just found this site today. I too am interested in converting my boat to electric. It is a 47 foot river cruiser with a shallow draft with a Volvo v8 sterndrive that I would like to remove. We plan on using solar and wind for our house power but am getting lost on all the electrical options or non-options. This a go slow boat. Are there any viable options out there?
