When two boats share the same hull type — in this case both the Ranger 173 Ghost 2010 and the Ranger 184 Ghost 2009 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 184 Ghost 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Ranger 173 Ghost 2010 tips the scales at 985 lbs — 880 lbs more than the Ranger 184 Ghost 2009 at 105 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 150 hp, the Ranger 184 Ghost 2009 has a 35-hp advantage over the Ranger 173 Ghost 2010's 115-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 184 Ghost 2009 carries 35 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Ranger 184 Ghost 2009 comes in at 1 lbs per hp versus 9 lbs per hp for the Ranger 173 Ghost 2010. 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.
