the 230+ and the 233 have some subtle differences is the wake. It mostly has to do with the orientation of the weight in the boat that has been changed by moving the windshield further forward. I don’t have a good reason for the 10K difference in price other than its the newest model so you are being charged a premium.
The 23x versus the 24x have a pretty big difference in wake size. The 244 is a deeper hull and a longer boat. More boat in the water= bigger wake for similar hulls. I get to ride a lot with the Inland surfer guys and Mac's new 233 wake is about 20% smaller than Mark's 244.
And sad to say i recently heard that they will not be making the 240+ anymore. They have not used the mold in almost 5 months. I would imagine that they are getting rid of the 240 to make room for a new mold in the shop
