Matching a cut diamond Malibu Response LXi 2008 against a modified vee Malibu Wakesetter 21 VLX 2013 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Malibu Wakesetter 21 VLX 2013 measures 21,5 feet overall (2013), giving it roughly 19,5 additional feet of deck space compared to the Malibu Response LXi 2008 at 2,0 feet (2008). At 28 lbs and 37 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 555 hp, the Malibu Wakesetter 21 VLX 2013 has a 155-hp advantage over the Malibu Response LXi 2008's 400-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 41 gal and 41 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Malibu Wakesetter 21 VLX 2013 is rated for 14 passengers, while the Malibu Response LXi 2008 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Malibu Wakesetter 21 VLX 2013 could be the deciding factor.
Bottom line: Choose the Malibu Wakesetter 21 VLX 2013 if your priority is putting more people on the water — it handles 14 passengers and at 21,5 ft it has the deck room to back that rating up comfortably. The Malibu Response LXi 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
