Halcyon was commissioned by the Lancashire industrialist Sir Samuel Turner in 1929 and he kept her until 1944. A Yachting Monthly article of 1929 spoke of her as “snugly rigged with Bermudan main and mizzen and a sail area of 2275 sq ft, and can be handled with a small crew”. Below deck the original teak saloon and main accommodation have been preserved perfectly throughout her long life. During the war we believe she was requisitioned by the navy and spent some time as the flagship of a minesweeper flotilla based in Greece. In 1957 she was acquired from Madame Renault by the Warsash School of Navigation in Hampshire as a temporary replacement for the ketch Moyana, the winner of the first Tall Ships race in 1956 which foundered off the Isles of Scilly on the return from her triumph. Halcyon proved so successful as a replacement training vessel that the British Merchant Cadet Training School kept her for 32 years.
