When two boats share the same hull type — in this case both the Aqua Patio AP 220 DC 2009 and the Aqua Patio AP240 SD 2007 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?
The power gap is worth calling out. Rated to 150 hp, the Aqua Patio AP 220 DC 2009 has a 25-hp advantage over the Aqua Patio AP240 SD 2007's 125-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 3 gal and 3 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Aqua Patio AP 220 DC 2009 is rated for 7 passengers, while the Aqua Patio AP240 SD 2007 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 AP 220 DC 2009 could be the deciding factor.
One place where both boats are genuinely identical is tube construction: both run 2 aluminum tubes at 25" 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: Choose the Aqua Patio AP 220 DC 2009 if your priority is putting more people on the water — it handles 7 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Aqua Patio AP240 SD 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
