The Cobia Boats 220 Dual Console 2013 is a deep-V design and the Cobia Boats 236WA 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 220 Dual Console 2013 at 21,6 ft versus Cobia Boats 236WA 2010 at 23,5 ft. Weight tells a clearer story for trailering families: the Cobia Boats 236WA 2010 tips the scales at 3 950 lbs - 1 000 lbs less than the Cobia Boats 220 Dual Console 2013 at 2 950 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 300 hp, the Cobia Boats 236WA 2010 has a 100-hp advantage over the Cobia Boats 220 Dual Console 2013's 200-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 236WA 2010 carries 138 gallons versus 89 gallons in the Cobia Boats 220 Dual Console 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 8 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: Performance buyers should lean toward the Cobia Boats 236WA 2010 and its 300-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Cobia Boats 220 Dual Console 2013 with its 200-hp rating is the more economical daily driver.
