I never been able to work this out. What ship was bigger ? Britannic or the Aquitania ? I suppose it is how you are going to look at it — some might go just by tonnage. I don’t... Aquitania always looked bigger to me. I’m sure her bridge would have been a couple of decks taller than that of the Olympic or Britannic. Having said that her the black painted area of her hull looks lower so perhaps the bridge height was not much taller. I understand Britannic was considered the largest British built ( or should I say Irish builtship since the Queen Mary — which is saying something ! From what I can work out both were probably larger in different ways. For example Aquitania might have been taller but Britannic might have been heavier. I do think if you were to see Aquitania or Britannic for real up close then out of the 2 ships Aquitania would appear the larger. But I might be wrong. But I think it is judged on tonnage - but not sure.
