The Donzi 28 ZX 2007 vs Donzi 38 ZR 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 38 ZR 2013 measures 38,7 feet overall (2013), giving it roughly 11,7 additional feet of deck space compared to the Donzi 28 ZX 2007 at 27,0 feet (2007). At 65 lbs and 95 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 2 700 hp, the Donzi 38 ZR 2013 has a 2 000-hp advantage over the Donzi 28 ZX 2007's 700-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 28 ZX 2007 carries 94 gallons versus 19 gallons in the Donzi 38 ZR 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 38 ZR 2013 is rated for 11 passengers, while the Donzi 28 ZX 2007 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Donzi 38 ZR 2013 could be the deciding factor.
