Both the Manitou Pontoons 20 Oasis VP 2013 and the Manitou Pontoons 22 Oasis 2009 are pontoon designs, the first built in aluminium and the second 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?
On paper these two are close siblings in the size department - Manitou Pontoons 20 Oasis VP 2013 at 20,8 ft versus Manitou Pontoons 22 Oasis 2009 at 22,0 ft.

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.

For family outings this is probably the sharpest distinction between the two. The Manitou Pontoons 22 Oasis 2009 is rated for 11 passengers, while the Manitou Pontoons 20 Oasis VP 2013 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Manitou Pontoons 22 Oasis 2009 could be the deciding factor.
One place where both boats are genuinely identical is tube construction: both run 3 aluminum tubes at 2" diameter. That shared spec means stability and buoyancy characteristics are closely matched - the ride difference you'll feel between them comes primarily from deck length, weight distribution, and motor choice.
Bottom line: Choose the Manitou Pontoons 22 Oasis 2009 if your priority is putting more people on the water - it handles 11 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The Manitou Pontoons 20 Oasis VP 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
