We are now back opposite the moorings at Lyon's Boatyard. As we approached we became aware of diesel on the water making its unmistakeable interference patterns. If I remember my school physics correctly, this is caused by light reflecting from the surface of the diesel combining with light reflecting from the water surface, just a molecular distance further. The thickness of the diesel is so small, approaching the wavelengths of light, interference patterns are set up revealing light's component colours in a rainbow effect. I'm sure someone will tell me if I've got this wrong.
The next day there was no evidence of the diesel.
This afternoon Scorpio came past.
