Thanks Tabman. You're the greatest.

I've left room in my layout for that size switch.
The boat is a Chris Craft Stinger 311, 400 horses of brand new Suzuki power. I'm thinking that 24" x 9s with a single ram would be a good match for this boat. I test drove one just like it that had Bennett 12" x 12s and it seemed under-tabbed to me, although that test was in calm water. Many boats of this size and shape have the long K-tabs, but I think they look like too much bling.
What size would you recommend?
