Ah, I see now. Jiangnan's ships also have aft deck extended.

The specificity of this particular series of containerships is, that they do not have FLAT BOTTOM but their underwater hull has a slight "V" shape form ... creates a certain problem when drydocking this ship !

There were 2 series, the HDW-built ships and the Jiangnan-built ships, main difference being that the so called Hump Deck extended fully forward on the HDW ships attached, whereas it was a true 'hump' on the Jiangnan ships (See IMO 9162617).... I think this makes the HDW ships the better looking. Interesting ships, designed for very fast feeder container work, there is not a flat plate on the bottom and they need special cradles for dry docking

At least this one doesn't look ugly compared to other ships of these series.
