This beast bares TWO nuclear reactors, with over 60 MW of propulsive power driving through anything in its path! Discover why we need so much power for an icebreaker.
Propulsion Classification

How Propulsion Works: Classifying Ship Propulsion

, , ,
No doubt, the math of propulsion devices is complicated. But it is all the same physics. By dividing each of these devices into their essential tasks, we find new opportunities. New methods of propulsion from different combinations of old tricks. Insight into this continuum allows us to better classify marine propulsion and dissect past successes to search for new combinations.

What 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

Waterjets: When to Use, Pros and Cons

, , , ,
Waterjets 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.
