The Moomba Gravity XLV 2011 vs Moomba Outback 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Moomba Gravity XLV 2011 measures 23,0 feet overall (2011), giving it roughly 21,0 additional feet of deck space compared to the Moomba Outback 2006 at 2,0 feet (2006). Weight tells a clearer story for trailering families: the Moomba Outback 2006 tips the scales at 275 lbs — 239 lbs less than the Moomba Gravity XLV 2011 at 36 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 Gravity XLV 2011 and 340 hp for the Moomba Outback 2006. 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 2006 carries 28 gallons versus 5 gallons in the Moomba Gravity XLV 2011. 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 2011 is rated for 16 passengers, while the Moomba Outback 2006 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Moomba Gravity XLV 2011 could be the deciding factor.
Bottom line: Choose the Moomba Gravity XLV 2011 if your priority is putting more people on the water — it handles 16 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Moomba Outback 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
