Thermopylae was an extraordinary composite clipper ship constructed in 1868 by Walter Hood & Co of Aberdeen, designed by Bernard Waymouth of London. She was built specifically for the China tea trade, featuring a length of 212 feet, a beam of 36 feet, and a depth of 20.9 feet. Her tonnage was recorded at 991 gross register tons (GRT), 948 net register tons (NRT), and 927 tons under deck. The hull construction employed American rock elm planking from the garboard to the light waterline, transitioning to teak from that point to the rail. The ship's composite design featured planking fastened over an iron frame, combining traditional wooden shipbuilding with iron reinforcement for strength and durability. Thermopylae was renowned for her sleek lines and exceptional speed, particularly in light winds and when sailing windward, making her highly effective in the China tea trade. Her hull design had a coefficient of under deck tonnage of 0.58, comparable to other fast clippers like Cutty Sark. She achieved a notable maiden voyage record, completing the trip from Gravesend to Melbourne in just 63 days, which remains one of the fastest sailings ever recorded. Her typical outward passages to Melbourne averaged 69 days, while her return voyages with tea cargoes averaged approximately 106.5 days. Her sailing performance was distinguished by her record-setting days' run of 380 statute miles, a feat unmatched by other sailing ships at the time. In 1872, she notably outpaced the clipper Cutty Sark in a race from Shanghai to London, winning by seven days after Cutty Sark's rudder failure. Thermopylae was particularly adept at sailing to windward and performing well in light airs, traits vital for the competitive tea and wool trades. As steam ships began to dominate, Thermopylae transitioned to the Australian wool trade from 1879, after a final tea run in 1881. Her rig was reduced to a barque, with further mast height reductions over time. In 1890, she was sold to Canadian owners for timber shipping, serving across the Pacific until her final voyage to Leith in 1895. She was sold to the Portuguese government, renamed Pedro Nunes, and intended as a training ship, but was ultimately used as a coal hulk. She was sunk by Whitehead torpedoes at the mouth of the Tagus River in 1907, marking the end of her notable maritime career.
