Forbach 41 club visited Reading Valley Veterans 41 Club, based in Sonning, last weekend.
The two groups took a boat trip from the River and Rowing museum to Hambleden Lock aboard Hobbs boat Consuta 2.
The trip was followed by lunch in the Thames Room at the River and Rowing museum and a tour of the galleries.
Will Lunn, who organised the day, said: “We thought it would be nice for them to see this wonderful stretch of the river in Henley. They wanted to see where the famous regatta takes place.”
The two groups have been twinned since 2006 and take it in turns to visit each other each year.
