When two boats share the same hull type — in this case both the Manitou Pontoons 20 Oasis VP 2013 and the Manitou Pontoons 22 ft. Oasis SHP 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 20 Oasis VP 2013 at 20,8 ft versus Manitou Pontoons 22 ft. Oasis SHP 2010 at 22,8 ft. Weight tells a clearer story for trailering families: the Manitou Pontoons 20 Oasis VP 2013 tips the scales at 2 135 lbs — 1 874 lbs more than the Manitou Pontoons 22 ft. Oasis SHP 2010 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.

The power gap is worth calling out. Rated to 250 hp, the Manitou Pontoons 22 ft. Oasis SHP 2010 has a 100-hp advantage over the Manitou Pontoons 20 Oasis VP 2013's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Manitou Pontoons 22 ft. Oasis SHP 2010 is rated for 11 passengers, while the Manitou Pontoons 20 Oasis VP 2013 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 ft. Oasis SHP 2010 could be the deciding factor.

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.
