jetbad

Jetbad is a concept related to personal watercraft, specifically referring to a type of water jet propulsion system. It's often used in the context of smaller, agile boats or stand-up watercraft. The fundamental principle behind a jetbad system is the intake of water from beneath the craft and its expulsion at high velocity through a nozzle at the rear. This expulsion of water creates thrust, propelling the watercraft forward.

Unlike propeller-driven boats, jetbad systems do not have external propellers that can be damaged by submerged objects or pose a hazard to swimmers. The intake is typically covered by a grate, preventing larger debris from entering the pump. The propulsion is controlled by directing the water jet, often through a steering nozzle. This allows for maneuverability, including the ability to turn sharply and even move in reverse by redirecting the water flow.

Jetbad systems are commonly found in personal watercraft (PWCs) like jet skis, although the term "jetbad" itself is not a universally standardized industry term. It's more of a descriptive or colloquial way to refer to the jet propulsion mechanism. The simplicity and safety aspects of jet propulsion have made it a popular choice for recreational water activities. The technology has evolved over the years, leading to more efficient and powerful jetbad systems.
