The Moomba Mobius LS 2005 vs Moomba Outback 2013 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 Outback 2013 measures 20,5 feet overall (2013), giving it roughly 18,5 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 — 267 lbs more than the Moomba Outback 2013 at 28 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 330 hp for the Moomba Outback 2013. 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 2005 carries 34 gallons versus 28 gallons in the Moomba Outback 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 1 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Moomba Outback 2013 at 20,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The Moomba Mobius LS 2005 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
