Malibu Response LX 2005 vs Malibu Sportster LX 2005: A Close Look at Two Modified-V Boats

Both the Malibu Response LX 2005 and the Malibu Sportster LX 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?

On paper these two are close siblings in the size department - Malibu Response LX 2005 at 20,0 ft versus Malibu Sportster LX 2005 at 20,0 ft. Weight tells a clearer story for trailering families: the Malibu Response LX 2005 tips the scales at 2 450 lbs - 200 lbs more than the Malibu Sportster LX 2005 at 2 250 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.

Both boats share a closely matched power ceiling - 400 hp for the Malibu Response LX 2005 and 400 hp for the Malibu Sportster LX 2005. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads - 35 gal and 38 gal - so range won't be a tiebreaker here.

Both boats are rated for 8 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Malibu Response LX 2005 and Malibu Sportster LX 2005 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Malibu Response LX 2005 vs Malibu Sportster LX 2005 - Common Questions

Which is the larger boat - the Malibu Response LX 2005 or the Malibu Sportster LX 2005?
The Malibu Sportster LX 2005 is the longer of the two at 20,0 feet overall. The Malibu Response LX 2005 comes in at 20,0 feet, making it roughly 0,0 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Malibu Response LX 2005 or the Malibu Sportster LX 2005?
For trailering, the Malibu Sportster LX 2005 has the edge at 2 250 lbs dry weight versus 2 450 lbs for the Malibu Response LX 2005.

How many people can each boat hold?
The Malibu Response LX 2005 is Coast Guard rated for 8 passengers, while the Malibu Sportster LX 2005 is certified for 8.

Which boat is wider, and does it affect trailering?
The Malibu Response LX 2005 measures 90" wide, compared to 86" for the Malibu Sportster LX 2005. The US standard-width towing limit is 8’6" (102") in most states - anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank - the Malibu Response LX 2005 or the Malibu Sportster LX 2005?
The Malibu Sportster LX 2005 has the bigger tank at 38 gallons, versus 35 gallons on the Malibu Response LX 2005. That 3-gallon difference translates to roughly 9–15 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Yes - both the Malibu Response LX 2005 and the Malibu Sportster LX 2005 are built by Malibu.
