The Nitro 929 CDX 2007 vs Nitro Z-6 2008 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department - Nitro 929 CDX 2007 at 20,0 ft versus Nitro Z-6 2008 at 17,0 ft. Weight tells a clearer story for trailering families: the Nitro 929 CDX 2007 tips the scales at 1 919 lbs - 569 lbs more than the Nitro Z-6 2008 at 1 350 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 300 hp, the Nitro 929 CDX 2007 has a 170-hp advantage over the Nitro Z-6 2008's 130-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Nitro 929 CDX 2007 carries 57 gallons versus 31 gallons in the Nitro Z-6 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.
Bottom line: The Nitro 929 CDX 2007 at 20,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Nitro Z-6 2008 at 17,0 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.
