Sometimes it’s all about timing: from the top of the drop to the bottom you can’t get your right hand forward because your paddle keeps clanging against the rocks beside and behind you on the right. As a consequence, your weight is thrown back, and you’ve lost all leverage. At 24 seconds, you need to plant a stroke on the right side, between you and the rock at the top, shifting the boat to a slight left angle (towards the V) so that you can keep your weight forward and plant another stroke on the right at the bottom of the drop for the bracing effect that John is describing. It’s mostly a matter of balance in your boat–in this case, the paddle position was throwing you off balance.
