First of all I second the Rinker 232, there were quite a few of them at my condo. They're not too fancy but they're bulletproof.
If you can stretch a little more, think about a 26 footer. It might save you in the long run, by skipping a step in the two foot disease. I owned a 2001 26 foot Searay bowrider, it was a great boat for the lake. I never felt unsafe. They stopped making that boat, but there are similar models, or Irwin still has mine for sale
I'd recommend a pump out toilet versus porta potty, much easier. In a 23-26 foot boat 50+ MPH starts to get you into a performance area. You might need to look at a Baja Islander.
