The Manitou Pontoons 18 Aurora 2007 vs Manitou Pontoons 22 Aurora 2007 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 Manitou Pontoons 22 Aurora 2007 measures 20,0 feet overall (2007), giving it roughly 4,0 additional feet of deck space compared to the Manitou Pontoons 18 Aurora 2007 at 16,0 feet (2007).

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 - 60 hp for the Manitou Pontoons 18 Aurora 2007 and 70 hp for the Manitou Pontoons 22 Aurora 2007. 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 Manitou Pontoons 22 Aurora 2007 is rated for 12 passengers, while the Manitou Pontoons 18 Aurora 2007 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Manitou Pontoons 22 Aurora 2007 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Manitou Pontoons 18 Aurora 2007 comes in at 24 lbs per hp versus 25 lbs per hp for the Manitou Pontoons 22 Aurora 2007. The lower the ratio the more explosive the acceleration - meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Both are inflatable designs, which means they pack down for compact storage, can be carried in a bag, and are dramatically lighter than equivalent rigid hulls. The trade-off is setup time and the need to monitor tube pressure regularly.
Bottom line: Choose the Manitou Pontoons 22 Aurora 2007 if your priority is putting more people on the water - it handles 12 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Manitou Pontoons 18 Aurora 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
