How to do get air in wakesurf

Just read a post in Wakeworld forum, I think it's readlly helpful:

James will start at the back of the pocket, typically his rear foot is in the curl. Then depending upon the pocket length and where the most crisp part of the wake FORWARD is, he'll pump once or twice so that he can hit that. Some wakes will have a rounded face before the top of the spine and that isn't a good launch spot. Focus on where the wake is it's sharpest and most forward.

Then James turns up and into that spot. From that point on, it's a skateboard ollie. Pull the front foot up and push down on the rear foot. The height of your air is going to be dependent upon how high you can pull that front foot up.

At the height of your pull your rear foot up to meet the height of your front foot. This is where you'll want a board that releases well of the wake.

If you look at the trough in the pictures you can estimate where James is starting from and also get an idea where he is projecting off the lip. In that second picture you can see how James is pulling that front foot up - he'll try and get that knee up towards his chest.

[the post with some pics, however, becoz the right of the photographer, I 'll not post them here. I find a video in youtube, the performer is also James ]
