The Windy 25 Mirage 2006 vs Windy 37 Grand Mistral 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.
Size is the most obvious dividing line here. The Windy 37 Grand Mistral 2006 measures 36,0 feet overall (2006), giving it roughly 11,0 additional feet of deck space compared to the Windy 25 Mirage 2006 at 25,0 feet (2006). Weight tells a clearer story for trailering families: the Windy 37 Grand Mistral 2006 tips the scales at 1 433 lbs — 948 lbs less than the Windy 25 Mirage 2006 at 485 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.
For family outings this is probably the sharpest distinction between the two. The Windy 37 Grand Mistral 2006 is rated for 11 passengers, while the Windy 25 Mirage 2006 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Windy 37 Grand Mistral 2006 could be the deciding factor.
Bottom line: Choose the Windy 37 Grand Mistral 2006 if your priority is putting more people on the water — it handles 11 passengers and at 36,0 ft it has the deck room to back that rating up comfortably. The Windy 25 Mirage 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
