The Mangusta Yachts Gransport 45 2023 vs Mangusta Yachts Maxi Open 80 2019 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 Mangusta Yachts Gransport 45 2023 measures 148,7 feet overall (2023), giving it roughly 66,5 additional feet of deck space compared to the Mangusta Yachts Maxi Open 80 2019 at 82,2 feet (2019). Weight tells a clearer story for trailering families: the Mangusta Yachts Gransport 45 2023 tips the scales at 628 300 lbs — 518 069 lbs more than the Mangusta Yachts Maxi Open 80 2019 at 110 231 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 2 600 hp, the Mangusta Yachts Gransport 45 2023 has a 200-hp advantage over the Mangusta Yachts Maxi Open 80 2019's 2 400-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Mangusta Yachts Maxi Open 80 2019 carries 1 452 gallons versus 14 gallons in the Mangusta Yachts Gransport 45 2023. 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 Mangusta Yachts Gransport 45 2023 is rated for 45 passengers, while the Mangusta Yachts Maxi Open 80 2019 caps at 25. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mangusta Yachts Gransport 45 2023 could be the deciding factor.
