K Brown, in his book "Warrior to Dreadnought" (Chatham Publishing, 1997), points out
that
"The maximum righting moment for Monarch (the Reed-designed contemporary to Captain)
was at 38° whist that for Captain was at !°# The Captain had a marginay greater
metacentric height than Monarch $ut the righting moment fe away once the dec% edge was
immersed and capsi&e was ine'ita$e once she had reached !°#"
(Survivor James Ellis is reported to have have heard a shipmate reporting to CaptainBurgoyne as disaster as imminent that the angle o! heel as 1"#$)
% & Bron goes on to summarise the mista'es as !ollos
- The concept of a fuy rigged ow-free$oard turret ship was wrong# *pencer Ro$inson and
Reed had pointed this out on numerous occasion# Coes+ $ad-tempered and unreasona$e
utterances confused the mind of the pu$ic and ministers ma%ing rationa de$ate impossi$e#
! - ,aiure to define responsi$iity $etween aird+s and the Controer particuary when
Coes+ iness pre'ented him from ta%ing any part#
3 - aird+s faiure to ta%e heed of Reed+s cear warning that the centre of gra'ity was higher
than they thought#
. - aird+s error in weight estimation which ed to her foating deeper than intended#
