Both the Malibu 21 vRIDE 2011 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 vRIDE 2011 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 vRIDE 2011 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.
The power gap is worth calling out. Rated to 450 hp, the Malibu Wakesetter 20 MXZ 2013 has a 40-hp advantage over the Malibu 21 vRIDE 2011's 410-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 21 vRIDE 2011 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: Performance buyers should lean toward the Malibu Wakesetter 20 MXZ 2013 and its 450-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Malibu 21 vRIDE 2011 with its 410-hp rating is the more economical daily driver.
