Next Level Hydrodynamics

Time for an upgrade! Far beyond the single purpose testing facility, the modern towing tank expanded into a Swiss Army knife of experiments. Armed with new gadgets and advanced capabilities. Time to see what new tricks the tank holds for us!

The Ship Towing Tank

The Ship Towing Tank

It may look like a swimming pool, but towing tanks exist for a different purpose. Dragging models down the tank propelled the science of ship design forward across the years. These pools deliver critical measurements for ship hydrodynamics. Discover why we pay such a high price for a fundamental tool of ship design.

How to Design a Waterjet: Key Elements of Waterjets

What makes a waterjet work? What is the difference between a good and bad waterjet? Waterjets may appear to be brutes of power, but they rely on delicately balanced design equations. Learn the common elements that go into all waterjets and discover the best practices that you should expect from any 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.

The TRUTH of Hull Speed:  How to Break the Sailing Speed Limit

The TRUTH of Hull Speed: How to Break the Sailing Speed Limit

Hull speed is bogus, but not because the math is wrong.  This formula supposedly predicts the maximum speed of a yacht based solely on length.  It gets discussed frequently in sailing yacht communities.  Surprisingly, hull speed is partially correct, with a very...
