Hmm, that's a pretty timid demo of a high brace. This is supposed to be a preparatory stroke to learning to roll. You have to get the boat right over on it's rail and get your ear wet before starting to learn to roll. You have to be able to recover from a complete 90 deg knock down before your high brace skill is adequately useful in rough water. Even, low brace you need to go much lower than this to be useful and prepare for combining strokes. To do a tight turn, you need to combine a forward sweep with edging, then go into a stern rudder on the opposite side, roll the boat right over on it's rail while transitioning the stern rudder into a reverse sweeping support stroke. This gets the ends of the boat clear of the surface so the long boat can spin freely. Then transition from the low grip support into the high grip still sweeping the blade forward to finish in a bow rudder position. While combining strokes may seem more advanced, you need to get to a whole lot more confident and committed with basic support than this. If your going to put training video up, you need to demonstrate the level of skill and confidence that students need to aim for. This is just nowhere near adequate. In fact, it's down right dangerous to give students the impression that this is an acceptable level of skill needed for safety at sea. It simply is not sufficient for safety at sea.
