Like those in many successful "marriages", sailors Jason Saunders and Paul Snow Hansen are polar opposites.
Saunders is Big Day Out, Snow Hansen is Laneway. But put them in a 470 boat and it works. The pair, who are both 21, finished eighth at last year's world championships sailed off Perth and have made such strides in recent times they must now be considered medal chances at this year's London Olympics.
They were in a position to win one halfway through the world championships, but slipped down the field at the pointy end of the competition.
"We are not similar people personality-wise," says Snow Hansen. "We are polar opposites. That can be a really big strength. We are always pushing ourselves by critiquing each other.
"I think we keep our on-water and off-water quite separate, which is a good thing," Saunders takes up.
