Both the Malibu Response 2006 and the Malibu Sunscape 247 LSV 2011 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?

The power gap is worth calling out. Rated to 555 hp, the Malibu Sunscape 247 LSV 2011 has a 155-hp advantage over the Malibu Response 2006's 400-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 247 LSV 2011 carries 87 gallons versus 35 gallons in the Malibu Response 2006. 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 247 LSV 2011 is rated for 17 passengers, while the Malibu Response 2006 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Malibu Sunscape 247 LSV 2011 could be the deciding factor.
