After riding in the SA I agree. However, has f you sit in the '06, then the SR, then the SA all back to back, it's amazing to feel the difference in a 10 year old 24' vs a new 21' boat. There is easily just as much USABLE cabin space as my 24'.
The one really odd thing about the new Supras is I don't feel like there's much storage space. In the 06 I keep a bunch of orange jackets under the seats in the nose. I can't do that with the ballast bag up there on the SA. The Enzo bags take up the storage under the seats in the cabin. The doghouse is about the only option to put stuff in, but I really want to put the W6's in there lol...
