Yes I do use a boat and when it comes to the blur it is 100% natural artificial blur just never looks right
Thanks a bunch for the comment

Thanks a lot for your response...
On the blur, I have to say I am surprised and even more appreciative of your skills. That is because at such high shutter speeds, the blur in water would only be attributed to your shallow DoF, and, for example, on your last picture (#8), I am surprised how the water is smoothly blurred all the way to the bird, even seemingly under the right wing which looks pretty sharp.
