The Moomba Mobius LS 2009 vs Moomba Outback LSV 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 Moomba Mobius LS 2009 measures 21,0 feet overall (2009), giving it roughly 19,0 additional feet of deck space compared to the Moomba Outback LSV 2005 at 2,0 feet (2005). Weight tells a clearer story for trailering families: the Moomba Mobius LS 2009 tips the scales at 315 lbs — 312 lbs more than the Moomba Outback LSV 2005 at 3 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 LS 2009 and 310 hp for the Moomba Outback LSV 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. Fuel capacity breaks the other way: the Moomba Mobius LS 2009 carries 34 gallons versus 4 gallons in the Moomba Outback LSV 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 LS 2009 is rated for 13 passengers, while the Moomba Outback LSV 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 LS 2009 could be the deciding factor.
Bottom line: Choose the Moomba Mobius LS 2009 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 LSV 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.
