Kevin, I had an '03 Maristar 230 (same as X-30)
As Corey stated it likes extra weight to create a nice wake. I had no stock ballast so I used 2 400# sacs in the rear lockers and a 750# sac in the walkway.....the wake was great!
Your wake will be more narrow if you pick up your speed to 22 or 22.5mph. Try that with a 65-70 ft line to get more time in the air for your roll.
The X-30 will make a great family wakeboard boat for you. The '03 used a unique wakeboard rack that you may want to stay away from. Try to find an '04-'05 instead. I think in '05 they started using JL speakers instead of Clarion which are better too. There was a rudder change sometime after '03 to a larger size rudder so upgrade to a newer rudder if you get a boat with the old style.
