The spec sheets list the Malibu vRide 2005 as modified vee and the Malibu Wakesetter VTX 2008 as v25 wake (cut diamond optional), 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 vRide 2005 at 21,0 ft versus Malibu Wakesetter VTX 2008 at 20,0 ft. Weight tells a clearer story for trailering families: the Malibu Wakesetter VTX 2008 tips the scales at 3 300 lbs - 300 lbs less than the Malibu vRide 2005 at 3 000 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.
Both boats share a closely matched power ceiling - 400 hp for the Malibu vRide 2005 and 400 hp for the Malibu Wakesetter VTX 2008. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Malibu Wakesetter VTX 2008 carries 46 gallons versus 35 gallons in the Malibu vRide 2005. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 10 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: The Malibu vRide 2005 and Malibu Wakesetter VTX 2008 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
