When two boats share the same hull type — in this case both the Manitou Pontoons 20 Encore Series 2011 and the Manitou Pontoons 20 Oasis - 8 Foot Wide 2008 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 20 Encore Series 2011 at 20,9 ft versus Manitou Pontoons 20 Oasis - 8 Foot Wide 2008 at 19,0 ft. Weight tells a clearer story for trailering families: the Manitou Pontoons 20 Encore Series 2011 tips the scales at 1 855 lbs — 1 689 lbs more than the Manitou Pontoons 20 Oasis - 8 Foot Wide 2008 at 166 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.

Both boats share a closely matched power ceiling — 90 hp for the Manitou Pontoons 20 Encore Series 2011 and 90 hp for the Manitou Pontoons 20 Oasis - 8 Foot Wide 2008. 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.

Both boats are rated for 1 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.

Both are 2-tube and 2-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity — more so than most buyers realize when comparing on paper.
