The on the face slash is a great turn for summertime's smaller waves because you don't need a lot of speed to pull it off. Look at how small this wave is, for example.
Many of the waves at my homebreak are slow on the outside and then speed up as they move closer to shore. I like to do this turn on the slower section because it's fun and doesn't burn the speed I need for the bigger turn I plan to do next on the inside section. Finally, the higher you do this turn on the wave, the more spray you will throw!
Gain a little speed by pumping down the line and then do a small bottom turn up the face of the wave. As you are bottom turning, get your wings out because you are going to need them to bring this turn around. Aim towards the top of the wave and look at the section you'd like to turn on.
|*I actually hate this shot, but as you can see, you can do a weak bottom turn and still pull this off.|
Step two:As you get to the top of the wave, plant your back foot and slightly turn your arms and upper body towards the beach, but not too hard. If you turn your whole upper body you will be doing more of a cutback and that will really burn your speed. What you're looking for is a quick fun slash before you set up for a bigger turn.
Crouch down and push your back foot towards your tail. Staying low is the key to success if you are doing this turn on small wave with a slow section. It is also very important to stay centered over your board so you don't loose your balance.
Let your fins readjust and find their line again before you move onto the next section.
I hope this helps you have more fun out there!
If you don't plan on surfing, then I hope you found this interesting :)
I learned so much of what I know from Taj Burrow's Book of Hot Surfing. It's a great surf book to own.
