You’re likely popping up too early, before the wave has properly lifted the tail of your board. You gotta feel the wave pick you up and push you first. If you’re too far forward on the board when you make your move, the nose digs in and you go over the falls. Focus on angling slightly down the line as you pop, and make sure you’ve caught the wave, not just the whitewater. Patience, mate—wait for that sweet spot of momentum.
