The Great Sound is a very different sailing venue to that of San Francisco. The wind on San Francisco Bay always comes from the west, which allowed race management to set the same course each day.
The weather in Bermuda, which sits alone in the middle of the Atlantic, is a lot more changeable and race management set the course each day according to the wind direction.
The light, fluky conditions during Monday saw the length of the legs shortened to 0.95 nautical miles for one of the races. Yesterday, in the heavier air, the runs extending out to 1.2nm.
During the racing, the on-water officials are constantly keeping a look out at any changes in wind direction, and adjusting the course accordingly.
"[On Monday] we changed the course probably three times - once during a race," said Murray.
"It's hard to massage these races depending on whether they get into a tacking duel at the start or are minute late, or have an incident.
"There are quite big shifts out there, that's sort of the part that makes it difficult and that's the part that makes a big difference to the speed of the boat around the track."
