The Nitro 929 CDX SC 2005 vs Nitro Z-8 2013 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.

Size is the most obvious dividing line here. The Nitro Z-8 2013 measures 20,1 feet overall (2013), giving it roughly 18,1 additional feet of deck space compared to the Nitro 929 CDX SC 2005 at 2,0 feet (2005). Weight tells a clearer story for trailering families: the Nitro 929 CDX SC 2005 tips the scales at 1 919 lbs — 1 900 lbs more than the Nitro Z-8 2013 at 19 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 SC 2005 has a 50-hp advantage over the Nitro Z-8 2013's 250-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 Z-8 2013 carries 68 gallons versus 57 gallons in the Nitro 929 CDX SC 2005. 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.
