The Charger 186 2011 is a modified-V design and the Charger SUV 210 DC 2008 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department - Charger 186 2011 at 18,5 ft versus Charger SUV 210 DC 2008 at 20,0 ft. Weight tells a clearer story for trailering families: the Charger SUV 210 DC 2008 tips the scales at 1 900 lbs - 600 lbs less than the Charger 186 2011 at 1 300 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 Charger 186 2011 has a 169-hp advantage over the Charger SUV 210 DC 2008's 6-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Charger SUV 210 DC 2008 carries 50 gallons versus 30 gallons in the Charger 186 2011. 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 Charger SUV 210 DC 2008 is rated for 6 passengers, while the Charger 186 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Charger SUV 210 DC 2008 could be the deciding factor.
Bottom line: Choose the Charger SUV 210 DC 2008 if your priority is putting more people on the water - it handles 6 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Charger 186 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
