Im new here, our boat and trailer are from the 80s and requires to be powerloaded onto the trailer. I like the current setup because I feel it is secure but would really like a winch. In the second picture you can see where I would like to have a winch post welded on, I'm wondering if it is safe to weld something to the coupler. I don't plan on having the winch be used to secure the boat while trailering, just to use it to get the boat on the trailer.
TIA
