What do people at Cowes Week know about sailing?

Cowes Week is the largest sailing regatta of its kind in the world.

The annual event attracts 100.000 people to the Isle of Wight, including about 8,500 sailors and more than 1,000 competing boats.

The event is also a big social occasion, so BBC South's Alexis Green joined the crowds to find out what they really knew about sailing.
