That was a pro photo shooting where the girl (and a boy) were showcasing bathing suits, I was the boat driver and took some shots with my camera, the photographer been using and old Canon 1D something and manual focus Zeiss lenses.
I drive the Riva every there and then and it's a joy, there is a few boats with such a smooth surfing through waves and the thrill when you push on the gas is hard to describe, the boat is small, less than 30' and the engine's roar is amazing.
...Glad I did, great shot of a beautiful woman.
