HMS Wolf
A torpedo-boat destroyer, a sister ship of HMS Seal
Wolf had suffered damage in a heavy sea before the loss of HMS Cobra
The Wolf was selected for a series of tests carried out in Portsmouth Dockyard, to check whether the calculation of strength was approximately correct; the results were published in 1905. The vessel successfully withstood in dock far greater stresses than the worst actually encountered at sea. The method of calculation employed (assuming the vessel were poised on a standard wave) was found to have overrated the real stress. Even so the design of hulls was strengthened.
