Early morning visitors in Plymouth Sound.

On Friday morning, just as the early cloud was beginning to clear and the sun started to take the edge off a bitter wind, two Dutch naval vessels entered the Sound and were led into the River Tamar and up river to berths in the Devonport Dockyard.

They were P842 HNLMS Friesland and P843 HNLMS Groningen.  (Check their full specification here)
