Priorities

Hello
I am a Naval Architecture student at Stevens Institute of Technology in Hoboken NJ. I am currently in the process of designing a Megayacht for my senior design project and need to develop an effectiveness analysis for sizing the yacht. It would be very useful to me if some of the owners on this forum could provide a list of their top priorities in purchasing or designing a yacht (speed, owners cabin, number of crew, entertainment feature, ect...) Thank you all very much for your time.
