Donzi 27 ZR 2009 vs Donzi Z-21 1987 — Same Brand, Different Boat

The Donzi 27 ZR 2009 vs Donzi Z-21 1987 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.

The power gap is worth calling out. Rated to 525 hp, the Donzi 27 ZR 2009 has a 175-hp advantage over the Donzi Z-21 1987's 350-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 27 ZR 2009 carries 86 gallons versus 66 gallons in the Donzi Z-21 1987. 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 27 ZR 2009 is rated for 8 passengers, while the Donzi Z-21 1987 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Donzi 27 ZR 2009 could be the deciding factor.

Bottom line: Choose the Donzi 27 ZR 2009 if your priority is putting more people on the water — it handles 8 passengers and at 27,2 ft it has the deck room to back that rating up comfortably. The Donzi Z-21 1987 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

Donzi 27 ZR 2009 vs Donzi Z-21 1987 — Common Questions

Which is the larger boat — the Donzi 27 ZR 2009 or the Donzi Z-21 1987?
The Donzi 27 ZR 2009 is the longer of the two at 27,2 feet overall. The Donzi Z-21 1987 comes in at 21,0 feet, making it roughly 6,2 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Donzi 27 ZR 2009 is rated to a maximum of 525 hp, giving it the larger power ceiling. The Donzi Z-21 1987 tops out at 350 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 27 ZR 2009 is Coast Guard rated for 8 passengers, while the Donzi Z-21 1987 is certified for 6. 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.
Which boat has the larger fuel tank — the Donzi 27 ZR 2009 or the Donzi Z-21 1987?
The Donzi 27 ZR 2009 has the bigger tank at 86 gallons, versus 66 gallons on the Donzi Z-21 1987. That 20-gallon difference translates to roughly 60–100 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Donzi 27 ZR 2009 and Donzi Z-21 1987 from the same manufacturer?
Yes — both the Donzi 27 ZR 2009 and the Donzi Z-21 1987 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.
