Easy to use, intuitive and powerful
3D view always on screen
A 3D view or your hull is always displayed on screen, you can move around the model as the calculations are happening. When you are doing a righting moment curve calculation, for example, you can see the boat heel and adjust to equilibrium, while the center of buoyancy and the center of gravity are always displayed in their correct positions.
Easy GZ curve calculations
It is surprisingly easy to get you first GZ curve done with HYDRO. Simply choose your geometry file, set the design displacemnt and design LCB, and get an accurate GZ curve with relevant data for each angle of heel.
Works with any kind of model
As long as your design software can output OFE offsets files, and most should be able to, HYDRO can take it in and give you accurate results in no time. It can calculate righting moments for an arbitrary center of gravity position, which means it gives accurate results for yachts with ballasts or canting keels.
While the beta version of HYDRO is currently free, once we all the features are fully implemented we will move to a paid subscription, the price of which will be astoundingly low compared to other software in this field. Although there may still be bugs in the system, so do not rely on it for anything mission critical just yet, but do let us know about any bug you encounter at [email protected].
