The 40 longest ships ever built

Ranked by length overall — supertankers, the entire 400-metre megamax club, the cruise giants and one enormous asterisk. Number one cannot sail, and number two no longer exists.

Length is the record with the best stories. The top of this board is dominated by the 1970s supertanker experiment — four French half-million-tonners and Exxon's twins, almost all scrapped young — crowned by Seawise Giant, the longest ship ever to sail, and out-measured only by Prelude FLNG, which was towed into place and will never make a voyage. Below them, an eleven-way pile-up at 399.9 metres marks the wall every modern container ship is built against.

* Prelude FLNG is included with an asterisk: at 488 m she is the longest floating structure ever built, but she has no propulsion and was moored permanently on delivery. The longest ship — a vessel that sails — is Seawise Giant. Lengths are the published LOA of each hull; sister ships share a class figure.
