Watercraft
The term
watercraft
covers a range of different water-borne
vehicles
:
including
ships
,
boats
,
hovercraft
and
submarines
. The term would
normally imply some propulsive capability (whether by sail, oar or engine)
and hence is distinct from a simple device that merely
floats
, such as a
log
raft
.
Terminology
Most watercraft would be described as either a
ship
or a
boat
. However,
there are numerous
craft
which many people would consider neither a ship
nor a boat, such as:
surfboards
(when used as a paddle board),
underwater
robots
,
seaplanes
,
jetskis
and
torpedoes
.
Although ships are typically larger than boats, the distinction between those
two categories is not one of size per se.
Ships
are typically large ocean-going vessels; whereas
boats
are
smaller, and typically travel most often on inland or coastal waters.
A
rule of thumb
says "a boat can fit on a ship, but a ship can't fit on a
boat", and a ship
usually
has sufficient size to carry its own boats, such
as
lifeboats
,
dinghies
, or
runabouts
.
Local
law
and regulation
may
define the exact size (or the number
of
masts
) that distinguishes a ship from a boat.
Traditionally,
submarines
were called "boats", perhaps reflecting their
cramped conditions: small size reduces the need for power, and thus
the need to surface or
snorkel
for a supply of the air that running
marine
diesel engines
requires; whereas, in contrast,
nuclear-powered
submarines
'
reactors
supply infinite power without consuming air, and
such craft are large, much roomier, and classed as ships in
some
navies
.
A
merchant ship
is any floating craft that transports cargo for the
purpose of earning revenue; in that context, a passenger ship's "cargo"
is its passengers.
