I use to to do almost everything at Delft Ship but unfortunately Propulsion Prediction not.
I use to use with students the program Free!Ship that has a lots of Propulsion Prediction methods. Of course none can be trusted at all since propulsion prediction is a trick thing, but for academic purposes is fine.
Delft Ship from version 8 on it’s not possible to Save As FBM version 2.6, the only one possible to open on FreeShip.
My question is if it’s possible to come back to include Save As FBM file as older as version 2.6?
