I really don't see how they could really work all that well, especially with his boat being covered up all the time...I mean 8 or 10 hours on the water can't be enough daylight to really charge his batteries that much - now if it was a whole week, that might be different...
Jesse Duncan has them and has not had to charge his battery all summer. He uses them on his Pontoon boat for party trips. The battery has lasted a couple of years like this. Keeps the battery charging any time it is not being used and prevents it from getting a hard no charge point.. or as some call it memory.
