Just ripped the floor up.

If you have nice straight bunks directly underneath the stringers, that is a helluva lot better than the hull resting on sets of rollers. When I was lookin at old v20s with jaysea, we saw one with rotten stringers on a roller trailer, and if you looked carefully you could actually see the hull deformed as the hull sagged around the rollers. Also, your full transom should help prevent outward bowing of the sides that removing the floor might otherwise allow. Just make sure your lines stay true and you should be ok. Don't want to throw a hook into that sweet hull.
The other thing to watch out for is "twist". About the best way to describe this is to think of a shoebox. Take off the top and see how easy it twists. The box top is like your floor. Of course, you still have your foredeck and cuddy bulkhead as well as your full transom to stop twist, but even a little twist is a bad thing on a high speed boat. If you put a jack in a stern corner you will see that you can lift that corner in isolation - that is "twist". Best to be sure you are straight and level BEFORE you pour, because when that seacast is set - that hull is gonna be rock solid. ;D

Sk, Thanks. I am gonna be perfectly level. And I really cant wait to drive this boat with a rock solid hull. It performed well last year. But it did have some rattle to it. Here on the gulf coast we have a lot of afternoon chop, and its always when your in a hurry to get somewhere. It'll be fun getting on top of it, with no worries.
