The spec sheets list the Malibu Wakesetter 23 LSV 2008 as v25 wake and the Malibu Wakesetter 23 XTi 2006 as modified vee, so check how each hull rides in the conditions you use before you decide.
On paper these two are close siblings in the size department - Malibu Wakesetter 23 LSV 2008 at 23,0 ft versus Malibu Wakesetter 23 XTi 2006 at 23,0 ft. Weight tells a clearer story for trailering families: the Malibu Wakesetter 23 LSV 2008 tips the scales at 3 900 lbs - 200 lbs more than the Malibu Wakesetter 23 XTi 2006 at 3 700 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 450 hp, the Malibu Wakesetter 23 LSV 2008 has a 50-hp advantage over the Malibu Wakesetter 23 XTi 2006's 400-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Malibu Wakesetter 23 LSV 2008 carries 55 gallons versus 47 gallons in the Malibu Wakesetter 23 XTi 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 14 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: Performance buyers should lean toward the Malibu Wakesetter 23 LSV 2008 and its 450-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Malibu Wakesetter 23 XTi 2006 with its 400-hp rating is the more economical daily driver.
