What a difference a day makes

Yesterday I watched the Navy engage in some kind of water-borne game with someone suspended from a helicopter.
Today, after a rather dull and dreary start to the day it brightened to a sharp, calm and almost warm day, with the inner harbour drenched in sunlight - it looked pristine and sparkling.
And then, instead of the navy or a helicopter, a small fleet of larger yachts found the time in the afternoon to set sail, and make the most of the perfect conditions.
