It is right that the new X-1, the current X-2 the old X-star and the Maristar 205V all have the same hull right? Which years have this hull for the X-star and the Maristar and what are the differences in ballast between the different boats? If you bought one of the first X2 hulls that had a worse ballast option how much would you be looking at to set it up nicely?
The hull came about in '96. The pre '01s had a two tank ballast system(I believe), and anything after had the triple KGB. I don't know if the new one will have a different system or not.
To summeraize what everyone else has said here is the complete list of the hull. '96-00 Prostar 205 '97-98 Xstar(D-drive) '99-02 Xstar(v-drive) '99-current 205V '03-05 X2 '06-current X1
