This appears to be a normal docking area for large boats that cannot be hoisted by crane out of the water. Once a boat has pulled in, and is shored up underneath, to be drained of all the water, thus leaving the boat in "dry dock" for repairs. When repairs are completed, the area is filled up with water and the boat is able to float again.
When you jump from a floating boat to a dock, the boat is also moving slightly on the water. Your momentum is aligned with the boat's motion rather than the stationary dock, causing you to fall short of the destination on the dock.
