When two boats share the same hull type — in this case both the Moomba Gravity XLV 2012 and the Moomba Outback V 2011 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?

Size is the most obvious dividing line here. The Moomba Gravity XLV 2012 measures 23,0 feet overall (2012), giving it roughly 21,0 additional feet of deck space compared to the Moomba Outback V 2011 at 2,0 feet (2011). At 36 lbs and 32 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 Gravity XLV 2012 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 5 gallons in the Moomba Gravity XLV 2012. 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 Gravity XLV 2012 is rated for 16 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 Gravity XLV 2012 could be the deciding factor.
