When two boats share the same hull type — in this case both the Ranger Z118 2013 and the Ranger Z20 Comanche 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?
Size is the most obvious dividing line here. The Ranger Z118 2013 measures 18,7 feet overall (2013), giving it roughly 16,7 additional feet of deck space compared to the Ranger Z20 Comanche 2009 at 2,0 feet (2009). Weight tells a clearer story for trailering families: the Ranger Z20 Comanche 2009 tips the scales at 1 735 lbs — 1 580 lbs less than the Ranger Z118 2013 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 225 hp, the Ranger Z20 Comanche 2009 has a 75-hp advantage over the Ranger Z118 2013's 150-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 Z20 Comanche 2009 carries 48 gallons versus 33 gallons in the Ranger Z118 2013. 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 Z20 Comanche 2009 is rated for 6 passengers, while the Ranger Z118 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Ranger Z20 Comanche 2009 could be the deciding factor.
Bottom line: Choose the Ranger Z20 Comanche 2009 if your priority is putting more people on the water — it handles 6 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Ranger Z118 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
