Published sources often give Nautilus and Albatross almost identical dimensions and displacement, yet their bow forms are visibly different. The framing needed to support those shapes likely changed the distribution of structural weight. That makes this a source-reading problem as well as a design point: nominal class figures are often rounded and can conceal ship-by-ship variation. The comparison warns against treating tabulated sameness as the last word on naval architecture.

When identical reference figures hide real ship differences
The visibly different bows of Nautilus and Albatross show why rounded displacement figures should not be mistaken for proof of identical construction.
