here the dominant point is the people in the bottom left hand corner. The eye is drawn from here to the boat behind it. It is the dominant point because of its size.
The dominant point here is the boat on the right hand corner. The viewers eye travels from this to the light house, then the ferry behind and then to the small boat in the background. Again it is size that make it the strongest point.
Here the dominant point is the boat, the next point is an area on the water behind and above it.
