When two boats share the same hull type — in this case both the Manitou Pontoons 22 Oasis SE Series 2011 and the Manitou Pontoons 23 25th Anniversary Edition SHP 2011 are pontoon designs with aluminum 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?
On paper these two are close siblings in the size department — Manitou Pontoons 22 Oasis SE Series 2011 at 24,3 ft versus Manitou Pontoons 23 25th Anniversary Edition SHP 2011 at 24,3 ft. Weight tells a clearer story for trailering families: the Manitou Pontoons 23 25th Anniversary Edition SHP 2011 tips the scales at 261 lbs — 232 lbs less than the Manitou Pontoons 22 Oasis SE Series 2011 at 29 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.
The power gap is worth calling out. Rated to 300 hp, the Manitou Pontoons 23 25th Anniversary Edition SHP 2011 has a 150-hp advantage over the Manitou Pontoons 22 Oasis SE Series 2011's 150-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 23 25th Anniversary Edition SHP 2011 carries 53 gallons versus 34 gallons in the Manitou Pontoons 22 Oasis SE Series 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 11 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
One place where both boats are genuinely identical is tube construction: both run 3 aluminum tubes at 23" 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: Performance buyers should lean toward the Manitou Pontoons 23 25th Anniversary Edition SHP 2011 and its 300-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Manitou Pontoons 22 Oasis SE Series 2011 with its 150-hp rating is the more economical daily driver.
