Both the Nitro 929 CDX 2008 and the Nitro Z-9 2011 are modified-V designs, the first built in aluminium and the second 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 - Nitro 929 CDX 2008 at 20,0 ft versus Nitro Z-9 2011 at 20,8 ft. Weight tells a clearer story for trailering families: the Nitro Z-9 2011 tips the scales at 2 100 lbs - 181 lbs less than the Nitro 929 CDX 2008 at 1 919 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 - 300 hp for the Nitro 929 CDX 2008 and 300 hp for the Nitro Z-9 2011. 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. Fuel capacity breaks the other way: the Nitro Z-9 2011 carries 66 gallons versus 57 gallons in the Nitro 929 CDX 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 4 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.
