I have two 12v fans but I've never considered hard-wiring them. I simply move them to where I need a fan. One of the two that I have, I bought at Auto Zone, it has a convenient clip and it plugs in to the cigarette lighter, or whatever those are called nowadays, and it has an eight foot cord that reaches in to the v-berth when I'm sleeping. It's surprisingly powerful and oscillates. I think I paid $12 for it.Has anyone added 12v cooling fans to their cabin for cooling? Where are best locations and how did you wire them to the boats 12v system?
Thanks for sharing your experience.
