Two-time Olympic silver medallist Nick Rogers has decided to end his quest for the gold medal at London 2012.
Rogers, 33, won silver in 2004 and 2008 in the 470 class with partner Joe Glanfield and aimed to go one step further with new team-mate Pom Green.
However, a frustrating regatta season and time constraints have forced the pair to call time on their London bid.
"Juggling responsibilities that we didn't have in our twenties has made it harder," said Rogers.
The pair, who won the 1995 Youth Sailing World Championships, retire with immediate effect and will not join their Great Britain team-mates at the 470 World Championships in the Netherlands on 12 July.
"We're best friends and it's been fantastic sailing with Pom again," said Rogers. "He's brought a lot of insight and experience to the campaign.
"Our goal was gold but it's just too much of a tall order in the time we have."
Rogers will now coach dinghy sailors and pursue other competitive sailing projects, while Green will return to yacht construction.
"It's been a great experience" said Green. "It's the end of an era for Nick and disappointing for me too but we both feel that to be successful in other areas of our lives something had to give."
Stephen Park, the Olympic manager for the Royal Yacht Association, said it was "disappointing to be losing Nick and Pom from the programme".
But he added: "Olympic classes sailing is a punishing game, and I understand and respect the decision that they have come to after what has been a frustrating season for them."
