When two boats share the same hull type — in this case both the Nitro 901 CDX 2008 and the Nitro Z-7 2011 are modified vee designs with aluminum 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 — Nitro 901 CDX 2008 at 19,0 ft versus Nitro Z-7 2011 at 18,7 ft. Weight tells a clearer story for trailering families: the Nitro 901 CDX 2008 tips the scales at 1 715 lbs — 1 550 lbs more than the Nitro Z-7 2011 at 165 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 — 200 hp for the Nitro 901 CDX 2008 and 200 hp for the Nitro Z-7 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 901 CDX 2008 carries 57 gallons versus 45 gallons in the Nitro Z-7 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 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.
