You have got to learn the basics. I think one must understand basic SLR photography first, then it does not matter what camera is in your hands. One of my good friends loves taking pictures and is great at framing and composition, but he won't take the time to understand the exposure process and it really hurts his photos. When you understand the basics of exposure, you will never use a programmed "mode" in you camera again, because then you will understand exactly what you want the camera to do.
In your pictures above, the shutter speed is too slow, that is all. Focus is fine. Looks like you are using a very small aperture, guessing F11 or F16 as everything is in focus, from the prop wash to the tops of the trees on the horizon. Also, is a very sunny day and in order for your shutter speed to get that slow, shutter speed is 1/250.
So here is my guess for your settings.
ISO 100, 1/250, f/16
The pictures would have been perfect at;
ISO 100, 1/1000, f/8
