When two boats share the same hull type — in this case both the Aqua Patio 220-4 2013 and the Aqua Patio AP 180 RE3 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?

Size is the most obvious dividing line here. The Aqua Patio 220-4 2013 measures 24,3 feet overall (2013), giving it roughly 5,3 additional feet of deck space compared to the Aqua Patio AP 180 RE3 2008 at 19,0 feet (2008). Weight tells a clearer story for trailering families: the Aqua Patio 220-4 2013 tips the scales at 3 078 lbs — 1 223 lbs more than the Aqua Patio AP 180 RE3 2008 at 1 855 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 150 hp, the Aqua Patio 220-4 2013 has a 70-hp advantage over the Aqua Patio AP 180 RE3 2008's 80-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Aqua Patio 220-4 2013 carries 29 gallons versus 3 gallons in the Aqua Patio AP 180 RE3 2008. 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 Aqua Patio 220-4 2013 is rated for 12 passengers, while the Aqua Patio AP 180 RE3 2008 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Aqua Patio 220-4 2013 could be the deciding factor.
