The Custom Weld 20 ft. Cobra 2012 is a deep-V design and the Custom Weld Cobra SE - 20 ft. 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 - Custom Weld 20 ft. Cobra 2012 at 20,0 ft versus Custom Weld Cobra SE - 20 ft. 2010 at 20,0 ft. At 2 700 lbs and 2 700 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling - 350 hp for the Custom Weld 20 ft. Cobra 2012 and 350 hp for the Custom Weld Cobra SE - 20 ft. 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads - 52 gal and 52 gal - so range won't be a tiebreaker here.
Both boats are rated for 6 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: The Custom Weld 20 ft. Cobra 2012 and Custom Weld Cobra SE - 20 ft. 2010 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
