Really nice explanations and visualizations. The discussion about ship stability and the moment arm between center of gravity and center of buoyancy gave me flashbacks of my undergrad aircraft stability and control classes (where the moment arms between CG and center of lift on the wings determines static stability).

The discussion about propeller design is also very similar to aircraft as well - not just aircraft propellers but also compressors in turbofan engines.

The fact that there's a ton of similarity between the disciplines isn't too surprising, but the great visuals in this blog post made that connection seem particularly satisfying.
