The 43 rowers and 12 boats in the British team for Beijing make it the largest contingent Britain has sent since 1992.
Six of those named - Grainger, Houghton, Flood, Winckless, Laverick and Steve Williams - won medals at the 2004 Olympics.
Williams took gold in the men's coxless four at Athens, and he believes the crew for 2008 will have to fight to repeat the performance.
"Everything is very intense now. Each crew in our event is moving towards the top of its game," he said.
"That's what they've been building up to for the last four years. I don't think the men's four has been this competitive since as far back as 1996."
