easier way is to get a buddy on a jetty or breakwater with the camera and time it on a strong incoming tide.
Even the smaller waves get the "boost" coming into a narrowed shallower chanel and make for some decent jumping.
Also solves the issue of the cameraman bouncing around if also on the water.
Just have to make sure you are not in a restricted speed zone or the "Baywatch Babes" will get you.
Also dont try to get too close to the jetty in case you loose it on the landing and end up parked on the rocks like this guy was
