Both the Moomba Mobius LS 2008 and the Moomba Outback V 2011 are modified-V designs, both built in fibreglass, so 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 LS 2008 at 21,0 ft versus Moomba Outback V 2011 at 20,0 ft. At 3 150 lbs and 3 200 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling - 325 hp for the Moomba Mobius LS 2008 and 325 hp for the Moomba Outback V 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 Outback V 2011 carries 39 gallons versus 34 gallons in the Moomba Mobius LS 2008. 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 2008 is rated for 13 passengers, while the Moomba Outback V 2011 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Moomba Mobius LS 2008 could be the deciding factor.
