The Moomba Mobius LS 2005 vs Moomba Mobius LSV 2006 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.
On paper these two are close siblings in the size department - Moomba Mobius LS 2005 at 20,0 ft versus Moomba Mobius LSV 2006 at 21,0 ft. Weight tells a clearer story for trailering families: the Moomba Mobius LSV 2006 tips the scales at 3 300 lbs - 350 lbs less than the Moomba Mobius LS 2005 at 2 950 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 340 hp, the Moomba Mobius LSV 2006 has a 30-hp advantage over the Moomba Mobius LS 2005's 310-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Moomba Mobius LSV 2006 carries 40 gallons versus 34 gallons in the Moomba Mobius LS 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 Moomba Mobius LSV 2006 is rated for 13 passengers, while the Moomba Mobius LS 2005 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Moomba Mobius LSV 2006 could be the deciding factor.
Bottom line: Choose the Moomba Mobius LSV 2006 if your priority is putting more people on the water - it handles 13 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Moomba Mobius LS 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
