Both the Malibu 21 RIDE 2013 and the Malibu Wakesetter 20 MXZ 2013 are modified-V designs, both built in fibreglass, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department - Malibu 21 RIDE 2013 at 21,5 ft versus Malibu Wakesetter 20 MXZ 2013 at 20,0 ft. Weight tells a clearer story for trailering families: the Malibu Wakesetter 20 MXZ 2013 tips the scales at 4 000 lbs - 500 lbs less than the Malibu 21 RIDE 2013 at 3 500 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 - 450 hp for the Malibu 21 RIDE 2013 and 450 hp for the Malibu Wakesetter 20 MXZ 2013. 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 21 RIDE 2013 carries 48 gallons versus 35 gallons in the Malibu Wakesetter 20 MXZ 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 13 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 21 RIDE 2013 and Malibu Wakesetter 20 MXZ 2013 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.
