I am currently evaluating Delfship Free for use designing radio controlled yachts, between 0.65m and 2m in length, 1kg to 15kg in displacement, intending to purchase the full version if suitable. I must say I am impressed with the speed and ease I can create shapes, but I find that the Real Time Hydrostatics and the Design Hydrostatic Report is not working. Curiously the Hull Transformation is giving me displacement and hull coefficients. I have tried drawing in actual measurements eg meters, and also treating 100cm as 100m. Neither seems to work. Am I missing something or is Delfship simply not suitable for my application.
