Not a big fan of the gimmicks and tricks like turning around and reversing your hands to drive anything. Better to understand what you are doing and why. It can help to put yourself where you can see what you are doing. Or at least put someone else who understands completely what you are doing to see for you and then be capable and willing to follow the directions relayed to you.

What is demonstrated very well in the kid video is the VERY SMART "bumping" the throttles in and out to limit speed to an absolute minimum anywhere near a dock or in a tight spot. Always you just the thrust you need then back in neutral. On the high performance fishing machines with big wheels, big engines, and little below the water to go fast that is critical. It is always important on any boat approaching a mooring or dock. If you are leaving the clutch in gear most of the time you are probably doing it wrong.

Here is how gimmicks coupled without basic knowledge + speed can get someone in trouble. Someone should have stopped that lady and boat as soon as she left that clutch in gear at the start of the approach.

If the kid just left those clutches in gear there would be no way to keep that type of boat under control. Just like the lady facing the wrong way to gain one advantage and losing all the others.
