When two boats share the same hull type — in this case both the Malibu FXi 2009 and the Malibu Sunscape 23 LSV 2012 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?
The power gap is worth calling out. Rated to 400 hp, the Malibu FXi 2009 has a 50-hp advantage over the Malibu Sunscape 23 LSV 2012's 350-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 Sunscape 23 LSV 2012 carries 53 gallons versus 46 gallons in the Malibu FXi 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Malibu Sunscape 23 LSV 2012 is rated for 15 passengers, while the Malibu FXi 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 Sunscape 23 LSV 2012 could be the deciding factor.
Bottom line: Choose the Malibu Sunscape 23 LSV 2012 if your priority is putting more people on the water — it handles 15 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Malibu FXi 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.
