When two boats share the same hull type — in this case both the Moomba Mobius XLV 2009 and the Moomba Outback V 2012 are modified vee designs with fiberglass construction — 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 Mobius XLV 2009 and 325 hp for the Moomba Outback V 2012. 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 Mobius XLV 2009 is rated for 16 passengers, while the Moomba Outback V 2012 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 XLV 2009 could be the deciding factor.
