Britain's best hope for Olympic gold comes in the men's lightweight double, manned by Zac Purchase and Mark Hunter.
The duo won all three World Cup events in 2008, although Denmark's two-time world champions Mads Rasmussen and Rasmus Quist are returning to form after struggling with illness earlier in the season and Italy also look strong.
Introduced to the Olympics in 1996, lightweight men's events have a maximum weight of 72.5kg for each rower, with a crew average of no more than 70kg.
Hunter, 30, a qualified Thames waterman, who was born and bred in the East End, has been in the GB senior squad for seven years but has only had real success since teaming up with Purchase last season, when they took world bronze.
Purchase (bottom right), 22 from Tewkesbury, won the lightweight single in a world record time at the 2006 World Championships but moved into the larger boat as the single is not an Olympic-class event.
They compete in heats from 0820 BST on 10 August, with semi-finals on Thursday and the final at 0750 the following Sunday.
