Windy 31 Zonda 2018 vs Windy 58 Zephyros 2006 — Same Brand, Different Boat

The Windy 31 Zonda 2018 vs Windy 58 Zephyros 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.

The Windy 31 Zonda 2018 carries a rated maximum of 400 hp. Engine data for the Windy 58 Zephyros 2006 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Windy 58 Zephyros 2006 carries 462 gallons versus 137 gallons in the Windy 31 Zonda 2018. 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 Windy 58 Zephyros 2006 is rated for 17 passengers, while the Windy 31 Zonda 2018 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Windy 58 Zephyros 2006 could be the deciding factor.

Bottom line: Choose the Windy 58 Zephyros 2006 if your priority is putting more people on the water — it handles 17 passengers and at 58,0 ft it has the deck room to back that rating up comfortably. The Windy 31 Zonda 2018 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
