'Spotted on the Forth'

parkrun day again! 

Fairly quiet weather on the prom at Cramond, with just a bit of a breeze back. 

A good turnout, over 600, with ages ranging from under 10 to over 85 and times from 15 and a half minutes to nearly an hour for the 5-kilometre course.

The sea looked calm, too, and I spotted these two vessels in the middle of the Firth of Forth near Inchkeith - around 8 miles away. 

I'd never seen them there before, but the bigger one looks like a dredger. Does anyone know what might be going on?
