Donzi 23 ZF 2005 vs Donzi 45 ZX 2006 - Boat Spec Comparison

Q: Which is the larger boat — the Donzi 23 ZF 2005 or the Donzi 45 ZX 2006?

The Donzi 45 ZX 2006 is the longer of the two at 45,0 feet overall. The Donzi 23 ZF 2005 comes in at 24,0 feet, making it roughly 21,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer — the Donzi 23 ZF 2005 or the Donzi 45 ZX 2006?

For trailering, the Donzi 45 ZX 2006 has the edge at 14 lbs dry weight versus 48 lbs for the Donzi 23 ZF 2005. 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.

Q: Which boat can handle a bigger outboard?

The Donzi 45 ZX 2006 is rated to a maximum of 2 700 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.

Q: How many people can each boat hold?

The Donzi 23 ZF 2005 is Coast Guard rated for 7 passengers, while the Donzi 45 ZX 2006 is certified for 13. 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.

Q: Which boat is wider, and does it affect trailering?

The Donzi 45 ZX 2006 measures 111" wide, compared to 102" for the Donzi 23 ZF 2005. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.

Q: Which boat has the larger fuel tank — the Donzi 23 ZF 2005 or the Donzi 45 ZX 2006?

The Donzi 45 ZX 2006 has the bigger tank at 409 gallons, versus 14 gallons on the Donzi 23 ZF 2005. That 395-gallon difference translates to roughly 1185–1975 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Donzi 23 ZF 2005 and Donzi 45 ZX 2006 from the same manufacturer?

Yes — both the Donzi 23 ZF 2005 and the Donzi 45 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.

Detailed Evaluation & Buyer Recommendation

Donzi 23 ZF 2005 vs Donzi 45 ZX 2006 — Same Brand, Different Boat

The Donzi 23 ZF 2005 vs Donzi 45 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.

Size is the most obvious dividing line here. The Donzi 45 ZX 2006 measures 45,0 feet overall (2006), giving it roughly 21,0 additional feet of deck space compared to the Donzi 23 ZF 2005 at 24,0 feet (2005). At 48 lbs and 14 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 45 ZX 2006 has a 2 400-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 45 ZX 2006 carries 409 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 45 ZX 2006 is rated for 13 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 45 ZX 2006 could be the deciding factor.

Bottom line: Choose the Donzi 45 ZX 2006 if your priority is putting more people on the water — it handles 13 passengers and at 45,0 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.
