This is what the fix looks like. The left side will be tricky for larger boats. Backing in will be kind of like threading a needle.
When we launched, I could give hand signals to the driver to keep the trailer centered. When we were leaving, it was a bit trickier for the driver as I was in the boat.
If you like watching people having 'adventures' while backing up a trailer, this could be a real hot spot. Hopefully they are not finished with the repair.
