There are a large number of sports that involve water. And when you are seeing an island, you just can’t leave all the fun in water. The following is a list of adventure sports.
Scuba diving is a mode of underwater diving in which a diver uses a self-contained underwater breathing apparatus (scuba) to breathe underwater. Unlike other modes of diving, which rely either on breath-hold or on breathing gas pumped from the surface. Scuba divers carry their own source of breathing gas. Usually compressed air, allowing them greater freedom of movement than with an air line or diver’s umbilical and longer underwater endurance than breath-hold.
Scuba equipment may be open circuit. In which exhaled gas is expelled to the surroundings, or a closed or semi-closed circuit re-breather. In which the breathing gas is scrubbed to remove carbon dioxide, and the oxygen used is replenished from a supply of feed gas before being re-breathed. A scuba diver primarily moves underwater by using fins attached to the feet. But external propulsion can be provided by a diver propulsion vehicle, or a sled pulled from the surface.
Current Sea Trek operations vary in depth from 3 to 10 meters. The maximum depth is not a function of the systems ability to provide air supply (operating pressure of 80 p.s.i.), rather a function of what is a safe operating depth for nonswimmers in case of emergency.
The air delivery is controlled by a microprocessor digital control system (A/C & D/C), providing the following primary functions:
A personal water craft (PWC), also called water scooter. This is a recreational watercraft that the rider sits or stands on, rather than inside of, as in a boat. PWCs have two style categories.
The first and most popular being a “sit down”, where the rider uses the watercraft mainly sitting down and typically holds two or more people.
The second style is a “stand up”, where the rider uses the watercraft standing up. The stand up styles are built for one rider and is used more for doing tricks, racing, and are used in competitions.
Both styles have an inboard engine driving a pump jet that has a screw-shaped impeller to create thrust for propulsion and steering. They are often referred by the trademarked brand names Jet Ski, WaveRunner, or Sea-Doo. Most are designed for two or three people, though four-passenger models exist.
The United States Coast Guard defines a personal watercraft, amongst other criteria, as a jet drive boat. Less than 13 feet (4 m) in length, in order to exclude from that definition more conventional sized jet boats.  There is a wide variety of “jet boats” many of which exceed 30–40 feet (9–12 m) in length.
Snorkeling (British and Commonwealth English 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 fins. In cooler waters, a wetsuit may also be worn. Use of this equipment allows the snorkeler to observe underwater attractions for extended periods with relatively little effort and to breathe while face-down at the surface.
Snorkeling is a popular recreational activity. Particularly at tropical resort 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. It appeals to all ages because of how little effort there is, and without the exhaled bubbles of scuba-diving equipment. It is the basis of the two surface disciplines of the underwater sport of finswimming.
Snorkeling is also used by scuba divers when on the surface, in underwater sports such as underwater hockey and underwater rugby, and as part of water-based searches conducted by search and rescue teams.
