Propulsive Devices

Propulsive devices are mechanisms used to generate thrust and propel a vessel through water. These devices can be categorized into two main types: mechanical and non-mechanical. Mechanical propulsive devices include propellers, water jets, and paddle wheels, while non-mechanical devices include sails and kites. Propellers are the most common mechanical propulsive devices and work by rotating blades to create a force that propels the vessel forward. Water jets, on the other hand, use a high-pressure stream of water to generate thrust. Paddle wheels are typically used in riverboats and work by rotating paddles to push water astern. Sails and kites are non-mechanical devices that use wind power to propel the vessel forward.
