I have a 2001 Santera with a tower and no automatic ballast. As far as I know it is the same as an SSV without the ballast system. The tower was a dealer installed item that year, so you could add that and search around and you will find ways to add an automatic ballast system. This would probably be for the back storage compartments only, about 270 lbs per side. You would want to balance it out with a 550 lbs sack on the floor in the bow. Because there is no ski locker in front to hide a sack. I have used this ballast setup and it works great.
