Time for an updated SeaHorse. Some internal polishing has been done, but nothing to tell your friends about. New outputs are more important: location of CoB and CoF in relation to WL length, as well as their World XYZ coordinates. Displacement-length and speed-length ratios should give more performance indicators for your hulls. Displacement speed is also added as an output, according to classic theory and light craft method presented in Dave Gerr's book. Known bugs - hull entry and exit angles still misbehave, sometimes computed correctly sometimes showing weird values, I'm working on implementing a better IQ for getting the correct angles. Lastly - the donate button collected 30.02EUR so far, thank you for your support !
