When two boats share the same hull type — in this case both the Donzi 35 ZF Open 2010 and the Donzi 35 ZFX Cuddy 2013 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 ZF Open 2010 at 33,3 ft versus Donzi 35 ZFX Cuddy 2013 at 33,3 ft. At 8 lbs and 8 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 700 hp, the Donzi 35 ZFX Cuddy 2013 has a 100-hp advantage over the Donzi 35 ZF Open 2010's 600-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 261 gal and 261 gal — so range won't be a tiebreaker here.

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.
