I dunno how this could've happened, but as I backed into the water, the boat somehow stayed on top of the water, but the trailer went straight down to the bottom and sunk about 6-8 inches.
But then I was able to pull it out when I pulled the truck forward. WHEW WHAT A RELIEF!
Now accepting donations to cover the gas it took to pull the trailer out.:crossx::crossx::crossx::crossx:
