Wing foil sizing from first principles
A wing-foil gear calculator that shows its working. Three regimes (float, wing-in-air, foil-in-water) joined into one coherent physical model, with the equations exposed and arguable rather than hidden behind rules of thumb.
Understanding Ship Deceleration: Interactive Calculator and Mathematical Methods
How long does it take a ship to stop? I built an interactive calculator and worked through the hydrodynamics from first principles. Without friction brakes, we can see that hull form and propulsion type dominate stopping performance.
