A few days ago I took a photo of Lake Windermere from Gummer's How. It is a stitched five shot image. In the middle/centre of that shot you'll see boats moored in a small bay.
This shot is an un-cropped shot of part of that bay.
That's how you did it...I did wonder seeing as you had got that length in, it worked beautifully. Love these small boats, all different but ready for the summer. My brother has a small sailing boat moored at the southern end of Windermere.
