Jetski on River Tyne

I want to do more jet ski photography and whilst browsing my archives I came across this man (and what I presume is his son) jet skiing down the River Tyne. They had just been through the centre of Newcastle and were heading west under the famous bridges. It was my intention to use this fast moving subject to practice my sports / motion photography to get the background blurred, but the subject sharp. Although my lens probably wasn’t quite long enough to get all the detail I wanted, they are as sharp as I could have hoped for.
