If cruise ships keep growing in size at the
rate they are, it now seems possible a cruise
ship could soon be built as large as Knock
Nevis. The largest cruise ships to hold the
title largest passenger ship in the world
Carnival Destiny, 1996,
101,353 grt, 893 feet long, 116 feet wide.
Grand Princess, 1998, 109,000
grt, 951 feet long, 118 feet wide.
Voyager of the Seas, 1999,

Oasis of the
Seas, 2009, 220,000 grt, 1,181 feet

Questions that may be asked are: what is GRT
(Gross Registered Tons).
Each ship has to be registered in size as
harbor duties are set by the ships bulk. The
measurement normally used for ships is Gross
Registered Tons. This is a volumetric measurement
that is worked out on the basis that, 100 cubic
feet is the equivalent to one Gross Registered
Ton. Warships are normally registered under
Displacement Tonnage. This is calculated by the
weight of water displaced by the ship after
completion. Each warship normally has three
different weights, light, standard and full load.
Unless stated otherwise, the ships weight should
be taken as standard. Crude oil tankers use GRT
and Dead Weight Tons, DWT meaning the weight of
water the ship displaces when fully loaded. GRT
is probably the best way to compare the actual
size of ships as it is worked out on volume. The
larger the GRT, the larger in dimension the hull
and superstructure are. It is hard to compare the
actual bulk of a warship against cruise ships and
tankers as it is hard to get the GRT of the
largest warships ever built, the 9 Nimitz
class aircraft carriers.
How does Freedom of the Seas have a
larger GRT than QM2 as she is shorter
The upper decks of QM2 step in from
the main hull of the ship plus she does not have
full height superstructure right at the stern as
does Freedom of the Seas, so less
How do cruise ships have so large a GRT giving
they are 3-4 hundred feet shorter than Knock
Knock Nevis sits about 80 feet in the
water when fully loaded with only around 30 feet
of hull above the waterline. The largest cruise
ships sit about 200 feet above the waterline with
only about 30 feet of their hull in the water.
Cruise ships are shorter and narrower but a lot
