I did have to straighten the horizon on this, the boat was not level at the time either

I use the camera for two things when they are doing this: to take photos and to read signals if we need to slow down or speed up the boat

I set the camera on continuous shooting mode to try to get good shots. I liked this one because they were all smiling.
Here is what I have of the boat, but it was going into dock so no speed action shots. It is a 19 foot boat with a V6 Volvo Penta motor. It does ok for speed. There are guys on the lake with faster and noisier. One guy nearby has dual outboard motors on his, but I am not sure the size as it is always moving too fast to read
