12v or USB Dehumidifiers for boat use (not mains voltage)

[ColinCattanach]

Anyone have any experience with these on boats left standing a bit in winter? Need to be plugged into USB or something and taking feed from house batteries which are hopefully charging enough during day to keep up with drain.

Anyone have any experience with small non-mains dehumidifiers? I am in NZ if that helps point to a supplier.

Thanks

Your best option is Damp Rid or similar
You can get it any where bunnings, Mitre 10 or any super market

Yeah we do damp rid but then into the whole packaging/plastic cycle. Never lasts that long. Was going to put solar day/night vents in hatches bit that breaks the integrity of the hull etc. Will get some rain shields for the sides as we have had them on our monohull and I love them !!
