The Cobia Boats 180 Dual Console 2013 is a deep-V design and the Cobia Boats 210WA 2010 is a modified-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 - Cobia Boats 180 Dual Console 2013 at 17,8 ft versus Cobia Boats 210WA 2010 at 20,3 ft. Weight tells a clearer story for trailering families: the Cobia Boats 210WA 2010 tips the scales at 2 750 lbs - 850 lbs less than the Cobia Boats 180 Dual Console 2013 at 1 900 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 200 hp, the Cobia Boats 210WA 2010 has a 50-hp advantage over the Cobia Boats 180 Dual Console 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 Cobia Boats 210WA 2010 carries 90 gallons versus 43 gallons in the Cobia Boats 180 Dual Console 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 Cobia Boats 210WA 2010 is rated for 8 passengers, while the Cobia Boats 180 Dual Console 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Cobia Boats 210WA 2010 could be the deciding factor.
Bottom line: Choose the Cobia Boats 210WA 2010 if your priority is putting more people on the water - it handles 8 passengers and at 20,3 ft it has the deck room to back that rating up comfortably. The Cobia Boats 180 Dual Console 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
