look, son I learnt to jump before I could jibe son. And i still cant jibe. Anyway you dont need big ramps to do good jumps like 2m, 4 m waves ect..you can do them in nothing, 0. The best way is to try a chop hop on flat water first thats how i learnt. But if you do try some of ya first jumps on some chop. This is what ya do first. So your on a plane your flying along and about to come up to ya first ramp. What ya do is when you hit the ramp is aim the board into the wind and use the lift from the wind. What i find is its not only the size of the ramp that makes a good jump its how much speed and wind under ya board you can get to lift ya board up. so remember to do the twist as you jump and aim into the wind. i try and aim allmost right into the wind sometimes if there is no chop.

another tip try to feel the speed of ya board dont try and go for a mass jump at first just a smooth jump will allways get ya higher
trying to go for a mass jump first you will end up stacking like i do all the time
here is 3 tips once ya get to planning speed and ya about to hit the waves or jump on smooth flat water
1. you first have to do a ollie on the board
2 turn the board into the wind
3. lift the board up with ya nees
and your away flying in the air but remember dont go too hard at first
a good jump is a smooth jump i have had some of my best air time when i have hardly tired to jump on me trusty jp excite, 120 L board
if ya dont know what a ollie is, google skate board ollie
If ya cant get air born, son next time ya try it come back and tell me, son
konas windsurfing jump tips allways get ya in the air, son[:D
