The Donzi 22 Shelby GT 2007 vs Donzi 35 ZR Open 2013 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 Donzi 35 ZR Open 2013 measures 35,3 feet overall (2013), giving it roughly 13,3 additional feet of deck space compared to the Donzi 22 Shelby GT 2007 at 22,0 feet (2007). At 34 lbs and 85 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.
The power gap is worth calling out. Rated to 1 200 hp, the Donzi 35 ZR Open 2013 has a 775-hp advantage over the Donzi 22 Shelby GT 2007's 425-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Donzi 22 Shelby GT 2007 carries 52 gallons versus 17 gallons in the Donzi 35 ZR Open 2013. 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 Donzi 35 ZR Open 2013 is rated for 10 passengers, while the Donzi 22 Shelby GT 2007 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Donzi 35 ZR Open 2013 could be the deciding factor.
Bottom line: Choose the Donzi 35 ZR Open 2013 if your priority is putting more people on the water — it handles 10 passengers and at 35,3 ft it has the deck room to back that rating up comfortably. The Donzi 22 Shelby GT 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
