Project Status

The headings below list and describe the tasks and steps completed that are necessary for the completion of the project.

Project Management

The project is broken down into five categories, each of which have a significant role in the final outcome of the design. The five categories of the project include the hull, skis, suspension and steering system, propulsion system, and the control system. Each member of the team is responsible for certain categories and will have authority in the design and manufacturing. The whole team is working together to make sure each is done well.


Suspension Design

Conventional personal watercraft rely on a directional water jet to steer. Jet Blade is unique in that the jet is fixed and steering is accomplished by turning the front skis. In order to achieve maximum turning performance, both skis must remain in contact with the water at all times. This requires the implementation of a tilt suspension system.


Ski Design

The three-ski design utilizes two skis in the front of the craft and one ski in the rear. The Jet Blade, when being operated, begins with the skis and a portion of the craft submerged. As the speed increases the skis begin to plane until the Jet Blade is completely out of the water and riding solely on the skis. While the skis are submerged there is little control of the vehicle. This is why it is important to design the skis large enough so that the Jet Blade can plane quickly.




Jet Pump and Engine

Similar to most personal watercraft, Jet Blade will implement a jet pump for thrust. A right angle gear box connects the impeller to a vertical-shaft engine. As the engine and pump assembly are the largest components, the Jet Blade will essentially be built around the propulsion system.







Research was done on different components of the Jet Blade. This has helped with design and calculations. The patent of the Wet Bike was a significant help and lead to the use of a Wet Bikes pump assembly and engine.






Final Draft of PPFS

The PPFS is the Preliminary Project Feasibility Study. This report details the research and design of the Jet Blade. The goal of the PPFS is to determine the feasibility of the final project. The full version of the PPFS can be found in the link provided on the Documents page.





Gantt Chart

By using a Gantt Chart the team has been able to practice project management skills. As the project has progressed the team has been modifying and updating the schedule.

About Us

The team consists of Josh Vanderbyl, Nico Ourensma, Ryan DeMeester and Zak DeVries. Each member of the team is part of the mechanical concentration of the engineering program at Calvin College. The team shares great interest in the outdoors and water activities. Our passions collided with our skills when the Jet Blade project was established.

Jet Blade

The Jet Blade is a single rider personal watercraft that is stable yet agile. The Jet Blade will incorporate a three-ski design that utilizes two skis in the front of the craft and one ski in the rear. These skis are located in spaced relation below an aluminum hull and operate to hydrodynamically lift the Jet Blade to a cruise position by relative water flow upon the undersides of the skis.
