The Manitou Pontoons 20 Osprey Pro 2007 vs Manitou Pontoons 22 Oasis Series 2011 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 Oasis Series 2011 measures 22,8 feet overall (2011), giving it roughly 3,8 additional feet of deck space compared to the Manitou Pontoons 20 Osprey Pro 2007 at 19,0 feet (2007). At 1 985 lbs and 2 015 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.
The power gap is worth calling out. Rated to 250 hp, the Manitou Pontoons 22 Oasis Series 2011 has a 160-hp advantage over the Manitou Pontoons 20 Osprey Pro 2007's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Manitou Pontoons 22 Oasis Series 2011 carries 34 gallons versus 28 gallons in the Manitou Pontoons 20 Osprey Pro 2007. 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 Manitou Pontoons 22 Oasis Series 2011 is rated for 13 passengers, while the Manitou Pontoons 20 Osprey Pro 2007 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Manitou Pontoons 22 Oasis Series 2011 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Manitou Pontoons 22 Oasis Series 2011 comes in at 8 lbs per hp versus 22 lbs per hp for the Manitou Pontoons 20 Osprey Pro 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.
The Manitou Pontoons 20 Osprey Pro 2007 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Manitou Pontoons 22 Oasis Series 2011 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: Choose the Manitou Pontoons 22 Oasis Series 2011 if your priority is putting more people on the water — it handles 13 passengers and at 22,8 ft it has the deck room to back that rating up comfortably. The Manitou Pontoons 20 Osprey Pro 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
