Tiger is 214.6 metres long, about 27.6 metres in beam and 9.9 metres in draught. Her thirty-nine Babcock and Wilcox boilers operate at 235 psi across five rooms. Four rooms have eight boilers and one has seven. Two Brown-Curtis turbine sets drive four shafts, with an output of 85,000 shaft horsepower. The nominal speed is 28 knots, while trials exceeded 29 knots and approached 30. These dimensions and machinery figures provide the comparison used for the hypothetical design.
