    Hello,

    How can I calculate the resistance and predict the power requirement for my conceptual small catamaran watercraft which I have the Rhino model to achieve a specific speed?

    You can recommend me software or hand calculation methods.

    Otherwise, estimate it from similar boats who's drag is "known".
