WELLINGTON (Reuters) - Peter Burling and Blair Tuke's impressive record since the last Olympics will mean little if the New Zealand sailors fail to put it all together on the day at next month's Rio de Janeiro Games.

Burling and Tuke, who won the silver medal in the men's 49er class at the London Games, won 27 successive regattas in the intervening four years -- a record for the class.
