A fresh conversion gives 143.56 metres for the first three D-class ships, the Danae batch. Rounded to one decimal place, that is 143.6 metres; the book prints 143.5 metres. The C-class comparison gives 137.61 metres against a printed 148.12 metres, a discrepancy described as about 11 metres. The spoken conclusion puts the D class about seven metres longer, although the two quoted lengths differ by about six metres. Both comparisons show the D class as longer and reverse the earlier conclusion. The correction changes the starting point for comparing hull form and expected speed.
