When two boats share the same hull type — in this case both the Donzi 28 ZX 2008 and the Donzi 38 ZSF Sportfish Cruiser 2013 are deep vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Donzi 38 ZSF Sportfish Cruiser 2013 measures 38,5 feet overall (2013), giving it roughly 11,5 additional feet of deck space compared to the Donzi 28 ZX 2008 at 27,0 feet (2008). At 65 lbs and 15 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 1 050 hp, the Donzi 38 ZSF Sportfish Cruiser 2013 has a 350-hp advantage over the Donzi 28 ZX 2008'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 2008 carries 94 gallons versus 42 gallons in the Donzi 38 ZSF Sportfish Cruiser 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 ZSF Sportfish Cruiser 2013 is rated for 11 passengers, while the Donzi 28 ZX 2008 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 ZSF Sportfish Cruiser 2013 could be the deciding factor.
