That Crash - SailGP Sydney Day 1

We've seen some collisions in SailGP but this one sent shivers down the spine. Thankfully no one was hurt. Great Britain SailGP Team, who were in the wrong, are now excluded from the rest of the Sydney event under the rules on serious collisions. Meanwhile Japan SailGP Team, whose boat is wrecked, are trying to figure out how they can keep their hopes of staying in the running for the big prize in the final in San Francisco next March alive. Sir Ben Ainslie and Nathan Outteridge explain what happened.
