When two boats share the same hull type — in this case both the Moomba Mobius LSV 2010 and the Moomba Outback 2011 are modified vee designs with fiberglass 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?
On paper these two are close siblings in the size department — Moomba Mobius LSV 2010 at 21,0 ft versus Moomba Outback 2011 at 20,5 ft. Weight tells a clearer story for trailering families: the Moomba Outback 2011 tips the scales at 275 lbs — 242 lbs less than the Moomba Mobius LSV 2010 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 — 325 hp for the Moomba Mobius LSV 2010 and 325 hp for the Moomba Outback 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 2010 carries 39 gallons versus 28 gallons in the Moomba Outback 2011. 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 2010 is rated for 13 passengers, while the Moomba Outback 2011 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 2010 could be the deciding factor.
Bottom line: Choose the Moomba Mobius LSV 2010 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 Outback 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
