When two boats share the same hull type — in this case both the Ranger 186 Reata 2008 and the Ranger 620T 2012 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 2008 at 18,0 ft versus Ranger 620T 2012 at 20,1 ft. Weight tells a clearer story for trailering families: the Ranger 186 Reata 2008 tips the scales at 1 845 lbs — 120 lbs more than the Ranger 620T 2012 at 1 725 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 175 hp, the Ranger 186 Reata 2008 has a 85-hp advantage over the Ranger 620T 2012's 90-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 620T 2012 carries 37 gallons versus 27 gallons in the Ranger 186 Reata 2008. 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 620T 2012 is rated for 6 passengers, while the Ranger 186 Reata 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Ranger 620T 2012 could be the deciding factor.
Bottom line: Choose the Ranger 620T 2012 if your priority is putting more people on the water — it handles 6 passengers and at 20,1 ft it has the deck room to back that rating up comfortably. The Ranger 186 Reata 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
