The Ranger 173 Ghost 2009 vs Ranger 621VS 2007 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.
Size is the most obvious dividing line here. The Ranger 621VS 2007 measures 21,0 feet overall (2007), giving it roughly 4,0 additional feet of deck space compared to the Ranger 173 Ghost 2009 at 17,0 feet (2009). Weight tells a clearer story for trailering families: the Ranger 173 Ghost 2009 tips the scales at 985 lbs — 758 lbs more than the Ranger 621VS 2007 at 227 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 300 hp, the Ranger 621VS 2007 has a 185-hp advantage over the Ranger 173 Ghost 2009'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 621VS 2007 carries 55 gallons versus 3 gallons in the Ranger 173 Ghost 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Ranger 621VS 2007 is rated for 6 passengers, while the Ranger 173 Ghost 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Ranger 621VS 2007 could be the deciding factor.
Bottom line: Choose the Ranger 621VS 2007 if your priority is putting more people on the water — it handles 6 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Ranger 173 Ghost 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
