Both the Donzi 35 ZF Cuddy 2009 and the Donzi 35 ZFX Cuddy 2010 are deep-V designs, both built in fibreglass, so 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 Cuddy 2009 at 33,3 ft versus Donzi 35 ZFX Cuddy 2010 at 33,3 ft. Weight tells a clearer story for trailering families: the Donzi 35 ZFX Cuddy 2010 tips the scales at 8 000 lbs - 300 lbs less than the Donzi 35 ZF Cuddy 2009 at 7 700 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.

Both boats share a closely matched power ceiling - 600 hp for the Donzi 35 ZF Cuddy 2009 and 600 hp for the Donzi 35 ZFX Cuddy 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. 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.
