Water Surfing

A banana boat (or water sled), is an unpowered, inflatable recreational boat meant for towing. Different models usually accommodate three to ten riders sitting on a larger, main tube and resting their feet on two laterally flanking tubes which stabilize the boat. The main tube is often yellow and banana-shaped. Some models have two main tubes.

A Water Scooter, 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

The Hippo water roller, or Hippo roller, is a device for carrying water more easily and efficiently than traditional methods, particularly in the developing world. It consists of a barrel-shaped container which holds the water and can roll along the ground, and a handle attached to the axis of the barrel. Currently deployed in rural Africa, its simple and purpose-built nature makes it an example of appropriate technology.
