How to Design a Waterjet: Key Elements of Waterjets
Fluid Dynamics, Fluids, Propulsion, Propulsion Plant, Transmission and Propulsor Systems, Waterjet PropulsorsWhat makes a waterjet work? Learn the common elements of all waterjets and best practices to expect from a decent waterjet design.

Waterjets: When to Use, Pros and Cons
Fluids, Propulsion, Propulsion Plant, Transmission and Propulsor Systems, Waterjet PropulsorsWaterjets are fun. They give you great maneuvering control and promise much higher efficiency at high speeds. But that flexibility comes with the price of more subtle limits on performance. Used incorrectly, waterjets perform worse than propellers. This article focuses on the merits of waterjets, with focus on the most important factor: efficiency.
