Matching a modified vee Malibu 21 LSV 2009 against a v25 wake Malibu Wakesetter VLX 2008 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.
Both boats share a closely matched power ceiling — 400 hp for the Malibu 21 LSV 2009 and 400 hp for the Malibu Wakesetter VLX 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. Both carry nearly identical fuel loads — 46 gal and 46 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Malibu 21 LSV 2009 is rated for 12 passengers, while the Malibu Wakesetter VLX 2008 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Malibu 21 LSV 2009 could be the deciding factor.
Bottom line: Choose the Malibu 21 LSV 2009 if your priority is putting more people on the water — it handles 12 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Malibu Wakesetter VLX 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.
