Cutty Sark and Thermopylae in the great Tea Race of 1872. [by Geoff Hunt] The Cutty Sark was by far the most powerful of the tea clippers. She lost her rudder near the end of the race, thus arriving a week later. The Thermopylae was built at the shipyard of Walter Hood Co., Aberdeen, in 1868 for George Thompson's "White Star Line". Sold to Canadian owners in 1890 who cut her down her rig to that of a barque.
