I would not discount Brett's ability.. He has raw natural speed talent!!
Who else do you know who can put a boat in the water on the day and win a race in the afternoon against an international fleet at a world titles!!! He has done this on more than one occasion!! If I recall the world Ts in Perth he won a heat (then ended up breaking bits and pieces as they were not tested before the racing started) and the world moths where he put on foils and learnt basically out in the titles!!
Maybe this time we will see Brett perform as he should with on water time before the titles start!! One can only hope..
