One photo showed a block on the back of the bunk board with nothing in the middle. I saw that often and then I would see the hull depressed in at the blocks. Please inspect your hull to make sure that is not happening. On the cable affixed to the bow eye, keep it loose but always attached if using that trailer for balancing or boat sitting on the trailer partaially. Good point about the keel cable being kept loose if resting the weight of the keel on the keel tray. Just be safe sir. There is only one of you.
