I have an older 26d. I had a lot of topside leaks and have rebedded almost everything. But that's for another day.
I would first check all through hulls that are below the water line.
I would check on top of the water ballast (I'm assuming the X has one and that you have screwed it down tight). I've heard of several that have had a leak on top of the water ballast, mine included. It's hard to see because it is hidden under everything.
Next I'd check the bow. Has it been hit or dinged?
Our cockpit drain was also somewhere water was coming in, but only when launching or healing was it under water. Had to have my spouse back the boat into the water, stopping every couple of feet until I saw the water gushing in around the through hull. Yes, we did this during the week when we had the ramp to ourselves (and no witnesses).
Good luck! This takes ruling out one place at a time or fixing one place at a time until you have a dry boat. You will learn a lot about the contours of your boat this way.
