Although the British team faced no competitors, due to misfortunes and delays suffered by other intending participants, the RAF High Speed Flight brought a total of six Supermarine Schneider racers to Calshot Spit on Southampton Water for training and practice. These aircraft were: S.5 serial number "N219", second at Venice in 1927, S.5 "N220", winner at Venice in 1927, two S.6s with new engines and redesignated as S.6As ("N247" that won at Calshot in 1929 and S.6A "N248", disqualified at Calshot in 1929), and the newly built S.6Bs, "S1595" and "S1596".
