When two boats share the same hull type — in this case both the Manitou Pontoons 23 25th Anniversary Edition SHP 2011 and the Manitou Pontoons 26 ft. Encore SHP I/O 2010 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 23 25th Anniversary Edition SHP 2011 at 24,3 ft versus Manitou Pontoons 26 ft. Encore SHP I/O 2010 at 26,6 ft. Weight tells a clearer story for trailering families: the Manitou Pontoons 26 ft. Encore SHP I/O 2010 tips the scales at 4 825 lbs — 4 564 lbs less than the Manitou Pontoons 23 25th Anniversary Edition SHP 2011 at 261 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.

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. 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 26 ft. Encore SHP I/O 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Encore SHP I/O 2010 caps at 1.

Both are 3-tube and 3-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity — more so than most buyers realize when comparing on paper.
Bottom line: Choose the Manitou Pontoons 23 25th Anniversary Edition SHP 2011 if your priority is putting more people on the water — it handles 11 passengers and at 24,3 ft it has the deck room to back that rating up comfortably.
