Shore power with a good charger. You batts will lose (assuming wet cells) about 5%/month just sitting there.
Off the grid apps require either a generator, wind, or solar. Which is best for you would be impossible to say. My best guess is that you will be stuck with solar if you are off grid. However, they are not awesome up north with your cloudy days.
You may be best off just pulling the batt out periodically and putting her un der a charge and returning it to the boat the next day. The other options, assuming you have no electricity, start getting a lot more expensive.
