Bodysurfing is the art and
sport of riding a wave
without the assistance of
any buoyant device such
as a surfboard or
bodyboard. Bodysurfers
typically equip themselves
only with a pair of
specialized swimfins that
stay on during turbulent
conditions and optimize
propulsion. Some
practitioners also carry or
wear a small planing
surface on the hand to aid
with positioning on the
wave face. These include
Hand Paddles, Hand
Guns, Wave Blades,
Redwings and others used
to gain extra speed across
the face of the wave.
Surfing is a surface water sport in which a
person (the surfer) rides a board (the surfboar
d)) on the crest of a wave as it carries the surfer
towards the shore.
Two major subdivisions within stand-up surfing
are longboarding and shortboarding, reflecting
differences in surfboard design including
surfboard length, and riding style.
In tow-in surfing (most often, but not
exclusively, associated with big wave surfing), a
motorized water vehicle, such as a personal
watercraft tows the surfer into the wave front,
helping the surfer match a large wave's higher
speed, a speed that is generally, but not
exclusively a speed that a self-propelled surfer
can not match.
Surfing-related sports such as paddleboarding
and sea kayaking do not require waves, and
other derivative sports such as kitesurfing and
windsurfing rely primarily on wind for power,
yet all of these platforms may also be used to
ride waves.
Fishing is the
activity of
catching fish.
Fish are
normally caught
in the wild.
Techniques for
catching fish
include hand
gathering,
spearing,
netting, angling
and trapping.
Sailing is the art of
controlling a boat with
large (usually fabric)
foils called sails. By
changing the rigging,
rudder, and sometimes
the keel or centre
board, a sailor
manages the force of
the wind on the sails in
order to change the
direction and speed of
a boat. Mastery of the
skill requires
experience in varying
wind and sea
conditions, as well as
knowledge concerning
sailboats themselves.
Scuba diving ("scuba" originally being
an acronym for Self Contained
Underwater Breathing Apparatus, now
widely considered a word in its own
right) is a form of underwater diving in
which a diver uses a scuba set to breathe
underwater for recreation, commercial
or industrial reasons.
Unlike early diving, which relied
exclusively on air pumped from the
surface, scuba divers carry their own
source of breathing gas (usually
compressed air), allowing them greater
freedom than with an air line. Both
surface supplied and scuba diving allow
divers to stay underwater significantly
longer than with breath-holding
techniques as used in snorkelling and
free-diving.
According to the purpose of the dive, a
diver usually moves underwater by
swimfins attached to the feet, but
external propulsion can come from an
underwater vehicle, or a sled pulled
from the surface.
Snorkeling (British spelling: snorkelling)
is the practice of swimming on or through
a body of water while equipped with a
diving mask, a shaped tube called a
snorkel, and usually swimfins. In cooler
waters, a wetsuit may also be worn. Use of
this equipment allows the snorkeler to
observe underwater attractions for
extended periods of time with relatively
little effort.
Snorkeling is a popular recreational
activity, particularly at tropical resort and
scuba diving locations. The primary appeal
is the opportunity to observe underwater
life in a natural setting without the
complicated equipment and training
required for scuba diving, and without the
exhaled bubbles of scuba-diving
equipment.
Snorkeling is also employed by scuba
divers when on the surface, and search and
rescue teams may snorkel as part of a
water-based search. It is also a means to an
end in popular sports such as underwater
hockey, underwater ice hockey,
underwater rugby and spearfishing.
Water skiing usually
begins with a deep water
start, with the skier
crouching down in the
water. When the skier is
ready, the driver
accelerates the boat to
pull the skier out of the
water.
Windsurfing is a
surface water sport that
combines elements of
surfing and sailing. It
consists of a board
usually two to four
meters long, powered
by the orthogonal effect
of the wind on a sail.
The rig is connected to
the board by a freerotating universal joint
and comprises a mast,
wishbone boom and
sail.
