The Nitro 591 SC 2006 vs Nitro 700 LX 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 700 LX DC 2005 at 17,0 ft. Weight tells a clearer story for trailering families: the Nitro 700 LX DC 2005 tips the scales at 1 183 lbs — 1 028 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.

The power gap is worth calling out. Rated to 200 hp, the Nitro 591 SC 2006 has a 75-hp advantage over the Nitro 700 LX DC 2005's 125-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 591 SC 2006 carries 43 gallons versus 24 gallons in the Nitro 700 LX DC 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Nitro 591 SC 2006 comes in at 1 lbs per hp versus 10 lbs per hp for the Nitro 700 LX DC 2005. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
