When two boats share the same hull type — in this case both the Malibu VTX 2009 and the Malibu Wakesetter 21 XTi 2007 are modified vee designs with fiberglass construction — 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?
Both boats share a closely matched power ceiling — 400 hp for the Malibu VTX 2009 and 400 hp for the Malibu Wakesetter 21 XTi 2007. 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 Wakesetter 21 XTi 2007 is rated for 12 passengers, while the Malibu VTX 2009 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Malibu Wakesetter 21 XTi 2007 could be the deciding factor.
Bottom line: Choose the Malibu Wakesetter 21 XTi 2007 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 VTX 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
