The Ranger Z20 COMANCHE SERIES 2006 vs Ranger Z518 Comanche 2012 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 Z518 Comanche 2012 measures 18,7 feet overall (2012), giving it roughly 16,7 additional feet of deck space compared to the Ranger Z20 COMANCHE SERIES 2006 at 2,0 feet (2006). At 176 lbs and 155 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 200 hp, the Ranger Z20 COMANCHE SERIES 2006 has a 50-hp advantage over the Ranger Z518 Comanche 2012'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 Z518 Comanche 2012 carries 33 gallons versus 24 gallons in the Ranger Z20 COMANCHE SERIES 2006. 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 SERIES 2006 is rated for 6 passengers, while the Ranger Z518 Comanche 2012 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 SERIES 2006 could be the deciding factor.
Bottom line: Choose the Ranger Z20 COMANCHE SERIES 2006 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 Z518 Comanche 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
