The Smoker Craft Infinity 2240 I-O 2005 vs Smoker Craft S-8521 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department — Smoker Craft Infinity 2240 I-O 2005 at 24,0 ft versus Smoker Craft S-8521 2006 at 21,0 ft. Weight tells a clearer story for trailering families: the Smoker Craft Infinity 2240 I-O 2005 tips the scales at 2 945 lbs — 2 750 lbs more than the Smoker Craft S-8521 2006 at 195 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 425 hp, the Smoker Craft Infinity 2240 I-O 2005 has a 300-hp advantage over the Smoker Craft S-8521 2006's 125-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Smoker Craft Infinity 2240 I-O 2005 carries 51 gallons versus 24 gallons in the Smoker Craft S-8521 2006. 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 Smoker Craft Infinity 2240 I-O 2005 is rated for 13 passengers, while the Smoker Craft S-8521 2006 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Smoker Craft Infinity 2240 I-O 2005 could be the deciding factor.
Bottom line: Choose the Smoker Craft Infinity 2240 I-O 2005 if your priority is putting more people on the water — it handles 13 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Smoker Craft S-8521 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
