The Absolute Yachts 40 STL 2015 vs Absolute Yachts 50 FLY 2017 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.
The power gap is worth calling out. Rated to 435 hp, the Absolute Yachts 50 FLY 2017 has a 105-hp advantage over the Absolute Yachts 40 STL 2015's 330-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Absolute Yachts 50 FLY 2017 carries 423 gallons versus 206 gallons in the Absolute Yachts 40 STL 2015. 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 Absolute Yachts 50 FLY 2017 is rated for 14 passengers, while the Absolute Yachts 40 STL 2015 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Absolute Yachts 50 FLY 2017 could be the deciding factor.
Bottom line: Choose the Absolute Yachts 50 FLY 2017 if your priority is putting more people on the water — it handles 14 passengers and at 49,1 ft it has the deck room to back that rating up comfortably. The Absolute Yachts 40 STL 2015 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.
