Jet drives have been proposed for auxiliary propulsion for sailboats on and off since the 1930s, perhaps earlier. The chief advantage would be minimum drag under sail; no prop, no strut, no shaft. Some racers have even tried a closure flap over the flush inlet hole. This leaves an absolutely smooth hull when under sail. There is, though, no special advantage with regard to engine placement; the engine and drive shaft have to be located to connect to the impeller as directly as possible to minimize power losses. Using a pump that is separate from the engine wastes too much horsepower. Unfortunately, the laws of physics make jet drive extremely inefficient for boats that operate at less than 25 knots, and that includes all sailboats.

Which function on PWC will not operate at idle speed?
A PWC or Jet Ski has a water Jet propulsion system. With this system the Jet drive is used for propulsion and steering. Jet drives dont turn without using the throttle unless moving very slow and even then it is limited.
What is a Johnson hydro electric drive?
A Johnson hydroelectric drive is a type of propulsion system used primarily in marine applications, particularly in small boats and watercraft. It utilizes a water jet or turbine system to convert the energy from flowing water into mechanical power, allowing for efficient movement through water. This drive system is known for its ability to provide high thrust and maneuverability while minimizing drag and enhancing fuel efficiency. Its design often integrates features that allow for easy maintenance and adaptability to various hull designs.
What can create a hazard in jet drive boats?
Hazards in jet drive boats can arise from shallow water, as the jet propulsion system can draw in debris or sand, potentially causing damage or reducing efficiency. Additionally, the high-speed water discharge can create a significant risk of injury to swimmers and water skiers nearby. Maneuverability in tight spaces can be challenging, increasing the risk of collisions with obstacles or other vessels. Lastly, improper maintenance of the jet drive system can lead to mechanical failures, posing safety risks on the water.
Is a sailboat less dense than water?
Yes, a sailboat is less dense than water, which allows it to float on the surface of the water. The buoyant force acting on the sailboat is greater than its weight, keeping it afloat.
Marine sailboat water system?
A marine sailboat water system typically consists of a freshwater tank, a pump, and a distribution network that supplies water to various outlets such as sinks, showers, and toilets. The system may also include a water heater and filtration components to ensure clean and safe drinking water. Many sailboats utilize a combination of onboard water storage and potential sources like rainwater collection or shore connections for refilling. Proper maintenance is essential to prevent leaks and ensure the system operates efficiently while at sea.
What makes a sailboat fast?
A sailboat's speed is influenced by several key factors, including its hull design, sail area, and weight distribution. A streamlined hull minimizes water resistance, while a larger sail area allows for better wind capture and propulsion. Additionally, the boat's rigging and the sailor's skill in trimming the sails and adjusting to wind conditions can significantly enhance performance. Overall, a combination of optimal design and effective sailing techniques contributes to a sailboat's speed.
Why dont your jet ski run in water but does on land?
If a jet ski runs on land but not in water, it could be due to several factors. Primarily, jet skis rely on water for propulsion; they use water intake to create thrust, so if there's insufficient water or a malfunction in the jet drive system, it won't operate properly. Additionally, the water may affect the engine's cooling system, as jet skis are designed to cool through the water they intake. Lastly, there could be issues with the fuel system or electrical components that only manifest in a water environment.
Why does a sailboat float?
A sailboat will have positive buoyancy if the weight of the boat is less than the weight of the water it takes the place of. The weight of the water that is being occupied by the hull is displacement.
What is the opposite force to water resistance?
The opposite force to water resistance is propulsion, which is the force generated by a watercraft's engine or other means to drive it forward through the water. It helps to overcome the resistance caused by the water and move the object in the desired direction.
What is the fuction of a squids water jet?
The water jet is a means of propulsion.
What is a yacht with water vapor propulsion as well as sails?
Most yachts employ both a propulsion device and sails.
What is the mechanism of propulsion on a Sea Doo?
Sea Doo personal watercraft, like almost all similar types of personal water vehicles, use a jet propulsion system rather than a traditional propeller motor like that on a standard boat. In jet propulsion, a water pump is powered by the engine to build up a set amount of pressure and when that pressure is released it causes the craft to be propelled into motion.
