Wind Generator and Charge Controller

In looking at some wind generators they recommend charge controllers. But KISS says to not use and gives various reasons including lost output. But not using a controller seems to be based on that you are on the boat and can turn it off, or that there is always enough power use going on that you could never damage the batteries from overcharge with the wind generator.

I am thinking of putting 1 on the boat that is on a mooring during the week and no one is on the boat. So it just seems to be a little crazy to not have controller and dump circuit and risk cooking the batteries.

But what is others using as far as controllers for your wind generators? If you don't use one do you leave the wind generator on when away from the boat for days? If you do use a controller has it seemed to reduce the charging you get from the generator?

It's a good idea to go with MFGR suggestions. My Air Breeze is internally controlled to go into stall mode when the battery bank is full. However, if I ran it through the charge controller I use for my solar bank, the wind generator would freewheel when the controller shut it off, which means that it would burn out its bearings in short order.
cruising is entirely about showing up--in boat shoes.
