Both the Moomba Liquid Force LSV 2010 and the Moomba Outback V 2010 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?
Both boats share a closely matched power ceiling - 325 hp for the Moomba Liquid Force LSV 2010 and 325 hp for the Moomba Outback V 2010. 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.
For family outings this is probably the sharpest distinction between the two. The Moomba Liquid Force LSV 2010 is rated for 13 passengers, while the Moomba Outback V 2010 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Moomba Liquid Force LSV 2010 could be the deciding factor.
Bottom line: Choose the Moomba Liquid Force 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 V 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
