The Nitro 591 SC 2006 vs Nitro 901 CDX DC 2005 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 591 SC 2006 at 18,0 ft versus Nitro 901 CDX DC 2005 at 19,0 ft. Weight tells a clearer story for trailering families: the Nitro 901 CDX DC 2005 tips the scales at 1 745 lbs — 1 590 lbs less than the Nitro 591 SC 2006 at 155 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 591 SC 2006 and 200 hp for the Nitro 901 CDX DC 2005. 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 DC 2005 carries 57 gallons versus 43 gallons in the Nitro 591 SC 2006. 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.
