I had a milwaukee 28 volt rite angle drill and winch bit. Very heavy, especially for my wife to handle. And it didnt seem to have the torque to do the job very well.
Acquired the 2nd version winchrite and love it. Battery lasts much longer, much easier to handle. I mounted the holder to the pedistal in the cockpit and ran a 12v wire, cut off the wall wart and spliced in the charger connector. So we have it on charge at the ready, easy to us.
My only complaint is that it is louder than the Milwaukee.
Dont know my sq ft off hand but we are 42', masthead rig of 62' with a 135 gen and in-mast main
