The verdict
Which is actually bigger?
The tanker is nearly 94 m longer — the length gap is almost exactly one football pitch — but Icon is the larger ship by internal volume. Longest ever versus biggest cruise ship: both records, one picture.
The Seawise Giant is the longer of the two, at 458.45 m against 364.75 m — a difference of 93.70 m. She is also the wider ship, by 20.15 m of beam, so she is the bigger vessel on both hull dimensions.
Seawise Giant is the longest self-propelled ship in history and probably always will be: 458.45 metres, 564,763 tonnes deadweight, bombed and sunk in the Iran–Iraq War, refloated, and worked for another two decades. Icon of the Seas rewrote the top of the cruise record books in January 2024 and held the world's-largest title until her sister ships matched and then narrowly exceeded her. Five times the gross tonnage of the Titanic. The silhouettes above are drawn at true relative scale from the sourced figures on each ship's page — same metres, same pixels, no artistic licence.
By gross tonnage — internal volume, the honest measure here — the Seawise Giant is the larger ship: 260,941 GT against 248,663.
