Terror’s original wales were 5½in thick, wrought ‘hook and butt’ fashion.

Doubling her hull for polar service was a complex process that involved adding different thicknesses of planks of varying species from her keel to gunwale. The refit of Terror for polar duty in 1836 followed a reinforcement plan that had been well-established from the time of William Edward Parry, who improved on earlier strengthening and doubling attempts for polar vessels. Terror’s original doubling was designed and implemented by Rice, who subsequently described how both Erebus and Terror were doubled to the same standard in 1839:³³
