@dan1166 just get the boat deep enough in the water that you can start the boat. Unhook it and gently back in deeper.
For pulling out, start with the trailer deep, you probably don’t need your truck tires in the lake, that can end badly. Bring the boat into to the trailer but not all the way in, just enough to hook up and have a few feet of strap with the boat making slight contact with the bunks. Make sure the strap is secure, now pull the trailer out to a more standard loading depth.
The boat nose will rise and should be high enough that the chines are off the bunks. Now you can crank the boat to the crash pads and get some help from the boat without pressuring the chines.
