Question - new to Supra but not new to Wakesurfing. We are currently in the process of finding a new boat. Our centurion Enzo is in the process of being sold and were eyeing up a low hour 2019 Supra SA to upgrade to. My question is around ballast options. Were there multiple ballast options on these boats when build/ordered new? I am seeing different drain configurations on these SA's when looking online. Some have 1 drain port and some have 3 ballast drain ports on the side of the boat which is puzzling to me?

Can anyone shine some light on this?

Much appreciated! Excited to get in to our first Supra!
