The Malibu Boats Wakesetter 20 VTX 2020 vs Malibu Sportster LX 2005 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Malibu Boats Wakesetter 20 VTX 2020 measures 20,0 feet overall (2020), giving it roughly 18,0 additional feet of deck space compared to the Malibu Sportster LX 2005 at 2,0 feet (2005). Weight tells a clearer story for trailering families: the Malibu Boats Wakesetter 20 VTX 2020 tips the scales at 3 950 lbs — 3 725 lbs more than the Malibu Sportster LX 2005 at 225 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 430 hp, the Malibu Boats Wakesetter 20 VTX 2020 has a 30-hp advantage over the Malibu Sportster LX 2005's 400-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 39 gal and 38 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Malibu Sportster LX 2005 is rated for 8 passengers, while the Malibu Boats Wakesetter 20 VTX 2020 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Malibu Sportster LX 2005 could be the deciding factor.
Bottom line: Choose the Malibu Sportster LX 2005 if your priority is putting more people on the water — it handles 8 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Malibu Boats Wakesetter 20 VTX 2020 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
