The Ranger 173 Ghost 2007 vs Ranger 618T 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 — Ranger 173 Ghost 2007 at 17,0 ft versus Ranger 618T 2008 at 18,0 ft. Weight tells a clearer story for trailering families: the Ranger 173 Ghost 2007 tips the scales at 985 lbs — 969 lbs more than the Ranger 618T 2008 at 16 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 115 hp, the Ranger 173 Ghost 2007 has a 25-hp advantage over the Ranger 618T 2008's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Ranger 618T 2008 carries 33 gallons versus 3 gallons in the Ranger 173 Ghost 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 5 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 Ranger 618T 2008 comes in at 0 lbs per hp versus 9 lbs per hp for the Ranger 173 Ghost 2007. 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.
