The Moomba Mobius LS 2005 vs Moomba Mobius LSV 2011 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 Moomba Mobius LSV 2011 measures 21,5 feet overall (2011), giving it roughly 19,5 additional feet of deck space compared to the Moomba Mobius LS 2005 at 2,0 feet (2005). Weight tells a clearer story for trailering families: the Moomba Mobius LS 2005 tips the scales at 295 lbs — 262 lbs more than the Moomba Mobius LSV 2011 at 33 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 — 310 hp for the Moomba Mobius LS 2005 and 325 hp for the Moomba Mobius LSV 2011. 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. Fuel capacity breaks the other way: the Moomba Mobius LSV 2011 carries 39 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 2011 is rated for 13 passengers, while the Moomba Mobius LS 2005 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Moomba Mobius LSV 2011 could be the deciding factor.
Bottom line: Choose the Moomba Mobius LSV 2011 if your priority is putting more people on the water — it handles 13 passengers and at 21,5 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 1 that costs less to run day-to-day.
