Eight years after his Olympic debut, Grabowski qualified again for his third Polish squad, as a 30-year-old veteran, in the Laser class at the 2008 Summer Olympics in Beijing. Although he performed poorly at the 2007 ISAF World Championships, Grabowski had secured a selection on the Polish team through the assistance of IOC's Olympic Solidarity scholarship. Unlike two of his previous Games, Grabowski failed to improve his Olympic feat with a surprising sixteen-place finish in a fleet of forty-three sailors at the end of ten-race series, giving him only a grade of 131.
