Squirt Boating
Squirt boating is a form of whitewater kayaking where the boat is designed to be as low in volume as possible while still allowing the paddler to float. Squirt boats are designed to use both surface and underwater currents to maneuver within the water. These maneuvers can be used to effect navigational control or to perform tricks. Overview Physically, a typical squirt boat is similar to a whitewater kayak (K1) or covered canoe (C1) but is distinct in the following ways: * The side profile of a squirt boat is very flat when compared to a whitewater kayak or C1. * The volume of a squirt boat is generally less than half of the volume of a normal kayak of the same length. This often ranges from 24–35 gallons (90–130 liters) for a squirt boat, but 50–70 gallons (190–260 liters) for a typical kayak. * Squirt boats often have foot bumps that enable the boat to maintain an ultra-low volume while still providing room for the feet. * When in the water, 70–80% of the boat will be ...

Whitewater Kayaking
Whitewater kayaking is an adventure sport where a river is navigated in a decked kayak. Whitewater kayaking includes several styles. River running; where the paddler follows a river and paddles rapids as they travel. Creeking usually involving smaller, steeper, and more technical waterways. Creek boats tend to be short but high volume to allow for manoeuvrability while maintaining buoyancy. Slalom requires paddlers to navigate through "gates" (coloured poles hanging above the river). Slalom is the only whitewater event to be in the Olympics. Play boating involves staying on one feature of the river and is more artistic than the others. Squirt boating uses low-volume boats (usually made specifically for the paddler) to perform special moves in whitewater features. History Paddling on rivers, lakes and oceans is as old as the Stone Age. The raft, the catamaran, the canoe and the kayak evolved depending on the needs and environment of the indigenous peoples in different parts of ...

Bernoulli's Principle
In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy. The principle is named after the Swiss mathematician and physicist Daniel Bernoulli, who published it in his book ''Hydrodynamica'' in 1738. Although Bernoulli deduced that pressure decreases when the flow speed increases, it was Leonhard Euler in 1752 who derived Bernoulli's equation in its usual form. The principle is only applicable for isentropic flows: when the effects of irreversible processes (like turbulence) and non-adiabatic processes (e.g. thermal radiation) are small and can be neglected. Bernoulli's principle can be applied to various types of fluid flow, resulting in various forms of Bernoulli's equation. The simple form of Bernoulli's equation is valid for incompressible flows (e.g. most liquid flows and gases moving at low Mach number). More advanced forms may be applied ...

Spraydeck
A spraydeck (sprayskirt in N. America, akuilisaq or tuiitsoq in Greenland) is a flexible waterproof cover for a boat (in particular for a kayak or a canoe) with holes for the passengers' waists. Spraydecks are used to prevent water from entering the boat while allowing passengers to paddle or row. Spraydecks are used in breaking waves, on whitewater, in inclement weather, and in splashy sports. An alternative is the tuilik. Construction A spraydeck is made of water-tight cloth or neoprene. It is sized to fit over the opening, or cockpit, of the canoe or kayak, with holes for the waists of the passengers. The spraydeck generally seals around the rim of the cockpit and around the torso of each passenger. Each opening in a spraydeck must make a fairly watertight seal. The seal varies in quality. The deck can be made to seal in several ways, including elastic fabric, a hem containing an elastic cord and/or drawstring, and both. Boat types Kayak spraydeck Spraydecks are worn by ...
