Getting heat to the v berth from the cabin?

[Wandering Sagebrush]

We use an Ecofan on our Wallas. It runs on the heat of the surface you set it on. You would have to have the Wallas top up to use this type of fan. No battery drain.

Another vote for the Eco Fan...

I bought the EcoFan! Im using it as we speak; sleeping in the boat tonight at the marina. Some of the folks here are doing a "last Saturday night" get together.

The EcoFan works pretty good for what its designed for. If I needed a winter option then I'd rethink it though.
