When two boats share the same hull type — in this case both the Malibu Sunsetter LXi 2005 and the Malibu Wakesetter 247 RX 2007 are modified vee designs with composite 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?
On paper these two are close siblings in the size department — Malibu Sunsetter LXi 2005 at 21,0 ft versus Malibu Wakesetter 247 RX 2007 at 24,0 ft. At 33 lbs and 4 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 450 hp, the Malibu Wakesetter 247 RX 2007 has a 50-hp advantage over the Malibu Sunsetter LXi 2005'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 — 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 247 RX 2007 is rated for 16 passengers, while the Malibu Sunsetter LXi 2005 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Malibu Wakesetter 247 RX 2007 could be the deciding factor.
Bottom line: Choose the Malibu Wakesetter 247 RX 2007 if your priority is putting more people on the water — it handles 16 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Malibu Sunsetter LXi 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
