Donzi 23 ZF 2005 vs Donzi 28 ZX 2006 — Same Brand, Different Boat

The Donzi 23 ZF 2005 vs Donzi 28 ZX 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.

On paper these two are close siblings in the size department — Donzi 23 ZF 2005 at 24,0 ft versus Donzi 28 ZX 2006 at 27,0 ft. Weight tells a clearer story for trailering families: the Donzi 28 ZX 2006 tips the scales at 655 lbs — 607 lbs less than the Donzi 23 ZF 2005 at 48 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 700 hp, the Donzi 28 ZX 2006 has a 400-hp advantage over the Donzi 23 ZF 2005's 300-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 2006 carries 94 gallons versus 14 gallons in the Donzi 23 ZF 2005. 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 28 ZX 2006 is rated for 8 passengers, while the Donzi 23 ZF 2005 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Donzi 28 ZX 2006 could be the deciding factor.

Bottom line: Choose the Donzi 28 ZX 2006 if your priority is putting more people on the water — it handles 8 passengers and at 27,0 ft it has the deck room to back that rating up comfortably. The Donzi 23 ZF 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.

Donzi 23 ZF 2005 vs Donzi 28 ZX 2006 — Common Questions

Which is the larger boat — the Donzi 23 ZF 2005 or the Donzi 28 ZX 2006?
The Donzi 28 ZX 2006 is the longer of the two at 27,0 feet overall. The Donzi 23 ZF 2005 comes in at 24,0 feet, making it roughly 3,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Donzi 23 ZF 2005 or the Donzi 28 ZX 2006?
For trailering, the Donzi 23 ZF 2005 has the edge at 48 lbs dry weight versus 655 lbs for the Donzi 28 ZX 2006. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Donzi 28 ZX 2006 is rated to a maximum of 700 hp, giving it the larger power ceiling. The Donzi 23 ZF 2005 tops out at 300 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Donzi 23 ZF 2005 is Coast Guard rated for 7 passengers, while the Donzi 28 ZX 2006 is certified for 8. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Donzi 23 ZF 2005 and Donzi 28 ZX 2006 share an 8 ft. 6 in. (2.59 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the Donzi 23 ZF 2005 or the Donzi 28 ZX 2006?
The Donzi 28 ZX 2006 has the bigger tank at 94 gallons, versus 14 gallons on the Donzi 23 ZF 2005. That 80-gallon difference translates to roughly 240–400 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Donzi 23 ZF 2005 and Donzi 28 ZX 2006 from the same manufacturer?
Yes — both the Donzi 23 ZF 2005 and the Donzi 28 ZX 2006 are built by Donzi. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
