Wow! to both the resulting photo and the loss of two cameras in one day! Bittersweet day of photography I guess?
What type of focal length lenses are you using when shooting from a jet ski?
When photographing from a jet ski, is the jet ski generally moving in some direction or does it try to remain stationary? I am guessing there is some creativity going on with the placement of the jet ski in relation to the surfer being photographed?
What were the type of cameras that got ruined? I am guessing "weather sealed" protection on most cameras is mist/rain type protection versus being submerged in a down pour of a crashing salt water wave?
Have you ever tried sufer shooting in the water with a housing? If so, what focal length lens is normally used?
