That inner glow was reinforced throughout the afternoon on both the outer Weymouth Bay courses, which looked like something out of the Southern Ocean. Big waves, fresh breezes, plenty of spray, cold temperatures. But it was all Brit, Brit, Brit.
One of the features of the Olympic sailing regatta is the prominent display of each countries national flag on the sails of the competitors.
Despite the hard conditions the sun shined through. And shone brightly on the Union Jack emblems on the sails of the British Star, Finn and 470 sailors.
It was a telling sight - even for those not blessed with British descent. The Brits were back.
Ainslie has cut his 10pt deficit to just three points, and few would now bet against him for the Gold medal. It will be no walk in the park - but 'Our Ben' is more than up to the test, and was on fire today at Weymouth.

Behind the ballooning British spinnaker in the Mens 470 class, was the stars of the Southern Cross - not quite ballooning, but streaming in the breeze.
The young crew of Paul Snow-Hansen and Jason Saunders, from New Zealand, had dropped their spinnaker halyard and were flogging the sail trying to get up to the gybe mark. They were in second place in just their first race in the Olympics, and sailing very well.
A slip from the trapeze by crewman Saunders, almost put the Kiwi pair in the drink, but they recovered well, and had a place nailed in the top three at the mark.
From there slipped a little more to finish eight, but nailed it in the second race of the day with a third place, and now lie in fourth place overall, ahead of the other crew with the Southern Cross on their sails - the world champions Mathew Belcher and Malcolm page (AUS).
Tomorrow will see the first race in the Womens 470 get underway - the final event to start at this Olympic Regatta.
The first medals will be awarded on Sunday.

But already the stories are developing from this regatta - the ones that will mark its place in the history of sailing.
