When two boats share the same hull type — in this case both the Aqua Patio AP 240 SD3 2009 and the Aqua Patio AP240 RE-4 Gate I/O 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?
On paper these two are close siblings in the size department — Aqua Patio AP 240 SD3 2009 at 25,0 ft versus Aqua Patio AP240 RE-4 Gate I/O 2007 at 24,0 ft. Weight tells a clearer story for trailering families: the Aqua Patio AP 240 SD3 2009 tips the scales at 3 125 lbs — 2 861 lbs more than the Aqua Patio AP240 RE-4 Gate I/O 2007 at 264 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 220 hp, the Aqua Patio AP240 RE-4 Gate I/O 2007 has a 70-hp advantage over the Aqua Patio AP 240 SD3 2009's 150-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 AP240 RE-4 Gate I/O 2007 carries 37 gallons versus 3 gallons in the Aqua Patio AP 240 SD3 2009. 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 AP240 RE-4 Gate I/O 2007 is rated for 14 passengers, while the Aqua Patio AP 240 SD3 2009 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 AP240 RE-4 Gate I/O 2007 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 AP240 RE-4 Gate I/O 2007 if your priority is putting more people on the water — it handles 14 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Aqua Patio AP 240 SD3 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
