Cayman Yachts F520 Flybridge 2019 vs Cayman Yachts S520 Sport 2021 — Same Brand, Different Boat

The Cayman Yachts F520 Flybridge 2019 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.

On paper these two are close siblings in the size department — Cayman Yachts F520 Flybridge 2019 at 52,4 ft versus Cayman Yachts S520 Sport 2021 at 52,4 ft. At 40 786 lbs and 40 785 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 435 hp for the Cayman Yachts F520 Flybridge 2019 and 434 hp for the Cayman Yachts S520 Sport 2021. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 370 gal and 370 gal — so range won't be a tiebreaker here.

Both boats are rated for 15 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Cayman Yachts F520 Flybridge 2019 and Cayman Yachts S520 Sport 2021 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
