How to do a Back Roundhouse
1. There are two main ways to set up for this move. Either carve your way to the top of the wave facing forwards and then do half a spin so you’re in a back surf or whilst back surfing carve your way to the top of the wave.
2. Then as you begin to come down the wave it is exactly the same as a front roundhouse but backwards. Start by angling your boat off to one side just slightly (lets start angled to the right).
3. As you begin to come down the wave drop that edge into the water (right edge)
4. Then immediately lift that edge out of the water dropping the other edge (left edge)
5. At the same time lean backwards slightly and do forward sweep (left blade) to spin you around to backwards.
6. Use a strong forward stroke (right blade) to stop the spin and keep you on the wave.
You need to switch edges quickly in order to make this move work.
Make sure you start pointing off to one side slightly. If you come down the wave straight as you turn you will be fighting the water rather than slicing through it making the move harder and you might find you get pushed flat every time.
The boat needs to rotate around the stern during the back roundhouse. So as you go to do your forwards stroke lean backwards. This puts the weight over your stern and makes the whole move pivot around the back of your boat.
Remember this whole move takes only a couple of seconds so make your movements explosive and snappy.
