When two boats share the same hull type — in this case both the Ranger 186 Reata 2013 and the Ranger Z521 Comanche 2011 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 186 Reata 2013 at 18,5 ft versus Ranger Z521 Comanche 2011 at 21,3 ft. Weight tells a clearer story for trailering families: the Ranger 186 Reata 2013 tips the scales at 1 845 lbs — 1 826 lbs more than the Ranger Z521 Comanche 2011 at 19 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 Z521 Comanche 2011 has a 85-hp advantage over the Ranger 186 Reata 2013's 140-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 Z521 Comanche 2011 carries 32 gallons versus 27 gallons in the Ranger 186 Reata 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 Z521 Comanche 2011 is rated for 6 passengers, while the Ranger 186 Reata 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 Z521 Comanche 2011 could be the deciding factor.
Bottom line: Choose the Ranger Z521 Comanche 2011 if your priority is putting more people on the water — it handles 6 passengers and at 21,3 ft it has the deck room to back that rating up comfortably. The Ranger 186 Reata 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.
