It's tough at the top.

An ideal afternoon for a walk around the Plymouth waterfront in warm sunshine, ice cream sellers doing a roaring trade as were the outdoor cafés. Here adjustments are being made to masthead gear on a yacht in the marina. The extra shows a piece of street art by the lock gates to Sutton Harbour, entrance to the River Plym and the arrival of a nuclear submarine - this was a couple of miles out and the light was fading.
