Or something like that... or does anyone know of a way to wire something in.

I have a Nico vent now, and it works well, but it is very sunburnt... brittle... I am going to upgrade to a newer unit, but I also want to put a full boat cover on.

So just looking for a way to keep venting the interior with solar fan while I have a cover on the boat. I have a cover that goes over the boom and cockpit and hatch, I want to extend it, which will cover my existing Nico vent.
