Both the Malibu Response FXi 2011 and the Malibu Sunscape 25 LSV 2005 are modified-V designs, so 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?

Size is the most obvious dividing line here. The Malibu Sunscape 25 LSV 2005 measures 25,0 feet overall (2005), giving it roughly 5,0 additional feet of deck space compared to the Malibu Response FXi 2011 at 20,0 feet (2011). Weight tells a clearer story for trailering families: the Malibu Sunscape 25 LSV 2005 tips the scales at 4 600 lbs - 1 400 lbs less than the Malibu Response FXi 2011 at 3 200 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 450 hp, the Malibu Sunscape 25 LSV 2005 has a 40-hp advantage over the Malibu Response FXi 2011's 410-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 25 LSV 2005 carries 80 gallons versus 40 gallons in the Malibu Response FXi 2011. 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 25 LSV 2005 is rated for 16 passengers, while the Malibu Response FXi 2011 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Malibu Sunscape 25 LSV 2005 could be the deciding factor.
