When two boats share the same hull type — in this case both the Donzi 35 ZFX 2008 and the Donzi 35 ZR Open 2011 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?

On paper these two are close siblings in the size department — Donzi 35 ZFX 2008 at 33,0 ft versus Donzi 35 ZR Open 2011 at 35,3 ft. Weight tells a clearer story for trailering families: the Donzi 35 ZFX 2008 tips the scales at 795 lbs — 710 lbs more than the Donzi 35 ZR Open 2011 at 85 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 1 200 hp, the Donzi 35 ZR Open 2011 has a 600-hp advantage over the Donzi 35 ZFX 2008's 600-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 35 ZFX 2008 carries 269 gallons versus 17 gallons in the Donzi 35 ZR Open 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 10 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.
