Both the Moomba Mobius LSV 2011 and the Moomba Outback V 2008 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 LSV 2011 at 21,5 ft versus Moomba Outback V 2008 at 20,0 ft. Weight tells a clearer story for trailering families: the Moomba Mobius LSV 2011 tips the scales at 3 300 lbs - 300 lbs more than the Moomba Outback V 2008 at 3 000 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 2011 and 325 hp for the Moomba Outback V 2008. 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. Both carry nearly identical fuel loads - 39 gal and 40 gal - so range won't be a tiebreaker here.

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 Outback V 2008 caps at 10. 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.
