Answer. We would recommend that you go no higher than a 16mm SWA cable, as the bending radius for a 25mm SWA cable makes it very difficult for you to get the cable around the back of the winch and make it off in the mast panel. Alternatively you could site a small feeder pillar adjacent to the mast and make off the larger supply cable in this, and then take a samaller feed cable from this feeder pillar to the mast panel.
