to provide the most economical answer to the majority of design requirements.
Some challenges to this supremacy may, however, be on the way: wave-piercing
catamarans are becoming competitive for passenger ships and the excellent sea-
keeping ability of the SWATH type of vessel enables a ship of this configuration to
be smaller than a competing monohull so that this type may become economically
competitive for a service in which minimum motions in a seaway are a prime need
- aircraft carriers and some research ships being distinct possibilities.
Monohull displacement ships can be divided into many categories, some of the
principal divisions by use being shown in Fig. 1.2. From a design point of view
there is, however, an alternative classification according to which design require-
ments are most critical in the determination of the main dimensions of the ship (a
subject discussed in Chapter 2).
