When two boats share the same hull type — in this case both the Ranger 173 Ghost 2010 and the Ranger 618T 2013 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Ranger 173 Ghost 2010 at 17,3 ft versus Ranger 618T 2013 at 18,3 ft. Weight tells a clearer story for trailering families: the Ranger 173 Ghost 2010 tips the scales at 985 lbs — 969 lbs more than the Ranger 618T 2013 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 2010 has a 25-hp advantage over the Ranger 618T 2013'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 2013 carries 31 gallons versus 3 gallons in the Ranger 173 Ghost 2010. 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.
