My buddy has an 08' 27 and I have an 08 28 and the hulls are not even close to the same. I would assume that they revamped the 28' hull on the speedster.

I also heard that the 06 + 27s have a new hull and that the new 26s have the old hull mold from the older 27s. There's a lot of fluff talk about the 26/27s sharing the same hull apparently as they are both 26' 10" long.
