The Donzi 28 ZX 2006 vs Donzi 29 ZF Open 2009 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 28 ZX 2006 at 27,0 ft versus Donzi 29 ZF Open 2009 at 28,6 ft. Weight tells a clearer story for trailering families: the Donzi 28 ZX 2006 tips the scales at 655 lbs — 593 lbs more than the Donzi 29 ZF Open 2009 at 62 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 150-hp advantage over the Donzi 29 ZF Open 2009's 550-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 18 gallons in the Donzi 29 ZF Open 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 8 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
