When two boats share the same hull type — in this case both the Manitou Pontoons 20 Encore 2009 and the Manitou Pontoons 22 Oasis 2009 are pontoon 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 Manitou Pontoons 22 Oasis 2009 measures 22,0 feet overall (2009), giving it roughly 20,0 additional feet of deck space compared to the Manitou Pontoons 20 Encore 2009 at 2,0 feet (2009). At 248 lbs and 261 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 Manitou Pontoons 20 Encore 2009 carries a rated maximum of 175 hp. Engine data for the Manitou Pontoons 22 Oasis 2009 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Manitou Pontoons 20 Encore 2009 carries 57 gallons versus 34 gallons in the Manitou Pontoons 22 Oasis 2009. 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 2009 is rated for 11 passengers, while the Manitou Pontoons 20 Encore 2009 caps at 1. 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.
