When two boats share the same hull type — in this case both the Malibu Response LX 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?

Size is the most obvious dividing line here. The Malibu Wakesetter 247 RX 2007 measures 24,0 feet overall (2007), giving it roughly 22,0 additional feet of deck space compared to the Malibu Response LX 2005 at 2,0 feet (2005). Weight tells a clearer story for trailering families: the Malibu Response LX 2005 tips the scales at 245 lbs — 241 lbs more than the Malibu Wakesetter 247 RX 2007 at 4 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 Wakesetter 247 RX 2007 has a 50-hp advantage over the Malibu Response LX 2005'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 Wakesetter 247 RX 2007 carries 46 gallons versus 35 gallons in the Malibu Response LX 2005. 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 Wakesetter 247 RX 2007 is rated for 16 passengers, while the Malibu Response LX 2005 caps at 8. 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.
