Start by keeping your shoulders more upright and square over the board to get into a better position. Wakeboarding is all about line tension and board resistance at the wake, if your shoulders are down you cannot resist or lean away as well. i appreciate in your video that the water is bumpy. You do not suck up to the wake like a girl at all! start a little wider and come in slower. Your position should be like you are perched on a stool, NOT like your sitting in a chair thats too low, and progressively lean away on your heels building the tension in the line. Resist at the wake with your arms in and low, relax on take off and absorb the shock as much as possible on landing.
you will tidy up with ease.
ps. the boat looks under weighted and a bit fast.
