Helen Glover and Annie Vernon hope their World Rowing Championship places will lead to them being selected for Team GB at the London 2012 Olympics.
Glover, 25, from Penzance will compete in the women's pairs, while Wadebridge's Vernon, 28, is in the women's quadruple scull squad.
"To become world champions would be great," Glover, who only took up rowing in 2008, told BBC Radio Cornwall.
"But we've also got to think about qualifying the boat for the Olympics."
Glover, who has already won a World Championship silver medal and a World Cup gold with partner Heather Stanning, added: "We're going to go there and row as best we can."
Vernon, who has been rowing at international level for seven years and won a silver medal at the Beijing Olympics in 2008, added: "Obviously being Cornish is something that's incredibly important to me.
"I remember when I was growing up it was all about the Cornwall rugby team and their victory at Twickenham. It was about people from Cornwall taking on the rest of the world and I hope I can take some of that bloody-mindedness with me."
