Would correcting Captain's weight problems make her another Monarch?

Would HMS Captain have been as successful as Monarch if the Admiralty had identified and corrected her material-weight problem?

Probably not, although the brief answer does not explain the alternative hypothesis about Captain.

Correcting the material-weight problem and low floating position of HMS Captain is judged unlikely to make her as successful as Monarch. A recent hypothesis about Captain is mentioned as the basis for a possible further historical discussion, but its content is not explained. The brief comparison therefore leaves the reasoning behind that judgement open.
