Why the Royal Navy stopped reusing the name Captain

Why was the name HMS Captain not reused for a major twentieth-century warship?

The 1870 loss of the unstable turret ship HMS Captain probably made the name too closely associated with disaster to reuse.

Several earlier ships of the line had carried the name Captain, and another ironclad was initially intended to receive it before launching as Agincourt. The final HMS Captain was the controversial low-freeboard turret ship that capsized in a gale off Cape Finisterre in 1870. That disaster is the most likely reason the name was not revived in either world war. The memory of a notorious loss can interrupt an otherwise established naming tradition.
