The Cayman Yachts F580 Flybridge 2021 vs Cayman Yachts S520 Sport 2021 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.

Size is the most obvious dividing line here. The Cayman Yachts F580 Flybridge 2021 measures 57,9 feet overall (2021), giving it roughly 5,5 additional feet of deck space compared to the Cayman Yachts S520 Sport 2021 at 52,4 feet (2021). Weight tells a clearer story for trailering families: the Cayman Yachts F580 Flybridge 2021 tips the scales at 52 911 lbs — 12 126 lbs more than the Cayman Yachts S520 Sport 2021 at 40 785 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 800 hp, the Cayman Yachts F580 Flybridge 2021 has a 366-hp advantage over the Cayman Yachts S520 Sport 2021's 434-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Cayman Yachts F580 Flybridge 2021 carries 528 gallons versus 370 gallons in the Cayman Yachts S520 Sport 2021. 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 Cayman Yachts F580 Flybridge 2021 is rated for 17 passengers, while the Cayman Yachts S520 Sport 2021 caps at 15. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Cayman Yachts F580 Flybridge 2021 could be the deciding factor.
