trailer
I would strongly suggest to replace any rope or equivalent by a steel chain, going from the bow eye down/back to the trailer.
When you pull your boat up, connect it to the bow eye when it can be done easily, then keep on winding until the chain length stops the boat.
One mistake is evident on your trailer : the bow eye must be level with the winch, not 8"above . You must raise the winch.
