 Both Britain and Italy entered two new aircraft and a backup plane from the previous race.Three of the four new aircraft were disqualified (Supermarine S.6 "N.248") or failed to finish the course (both Macchi M.67s), with the older Macchi M.52R taking second and Supermarine S.5 taking third.Although France had ordered racing seaplanes from Bernard and Nieuport-Delage in 1928, they were unable to complete them in time for the 1929 race.
