Rowers to boast Australia's biggest team

Rowing Australia will send the country's biggest sporting team to the London Games after successfully qualifying a "lucky 13" boats for the Olympic regatta.

Australia sealed 47 rowing positions for the Olympics after three crews gained last-ditch places for London during the final qualifying regatta in Switzerland.

The number takes rowing above swimming (44), athletics (likely 41) and cycling (30) as the biggest Australian teams in the Olympic village when the Games start on July 27.

Rowing Australia pre-qualified 10 boats at last year's world titles, but single sculler Kim Crow and lightweight doubles sculls duo Tom Gibson and Rod Chisholm on Thursday morning (AEST) added to the efforts of the women's eight in Lucerne.

The men's single scull is the only class Australia won't be represented in, giving Germany the biggest rowing team in London after managing to qualify all 14 boats.

Hosts Great Britain will also have 13 crews in action at Eton Dorney but it remains to be seen whether Australia enters each of their boats.

Premier female sculler Crow has given herself the option of competing in the single or double sculls or both with her victory in Lucerne.

The Victorian entered the race for race practice and an insurance policy while doubles partner Brooke Pratley, who flies from Canberra to Europe on Friday, recovers from a rib injury.

A silver medallist at the 2010 and 2011 world titles in the double sculls with Kerry Hore, Crow showed her class by winning by three seconds and will compete in the small boat in World Cup 2 on the same course this weekend.

She has pedigree with a bronze World Cup medal in 2009 and Crow will get a strong gauge of her current form by racing against Belarussian great Ekaterina Karsten and Czech veteran Mirka Knapkova.

Tasmanian Gibson and NSW's Chisholm needed a top-two finish and, in a superb sprint to the line, they rowed through USA in the final 500 metres to place second behind Hungary in six minutes and 28.21 seconds.

"The reality is if we had not got the result we needed today, then we would have been on a plane home tomorrow," Gibson said. "We knew what we needed coming into this regatta and we are both so happy to have qualified for London.

"Both our wives are over here with us, but mine was too nervous to come down to the course today."
