Read this thread, this method by cnski and RobM works much easier than any other i have tried:

"""1) I put the wing up on the board holding onto the front handle I will be using while riding (not LE handle).
2) I then climb up onto the board on my stomach in prone surf paddle position still holding the handle on top the board with the wing over the top of me (it helps that I am on the Duo Unit with dihedral so the upper half of the wing isn't resting directly on me. The lower half is flat on the water much like in my picture I posted above).
3) I then simultaneously push down on the board with my front hand (still holding the wing handle on the nose of the board) and my back hand (which is free and close to the rail about mid board or maybe a little more towards the tail) and quickly pop up onto my knees keeping my head and shoulders low. As soon as I am on my knees I quickly raise the wing and grab the back handle (everything soon stabilizes).
4) Now I am in classic knee start position with wing powered up overhead. It's all normal from there and doable!!!
This method is so quick and easy!! I too cannot mount a sinker board onto my knees with the wing floating beside me. Tried and failed many many times. A sink start seems too hard, slow and obviously need deeper water. I ride strapless so a waterstart is pretty much out of the question, and I'm almost positive I could never pull off Alan Cadiz's sit start. Very cool RobM that we are doing the same thing. It seems so intuitive. Should we name it? Quick start? Wingover start? The Stinkbug start? :-) """"
