Custom Weld 20 ft. Cobra 2013 vs Custom Weld Storm - 21 ft. 2006 — Same Brand, Different Boat

The Custom Weld 20 ft. Cobra 2013 vs Custom Weld Storm - 21 ft. 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Custom Weld Storm - 21 ft. 2006 measures 21,0 feet overall (2006), giving it roughly 19,0 additional feet of deck space compared to the Custom Weld 20 ft. Cobra 2013 at 2,0 feet (2013). Weight tells a clearer story for trailering families: the Custom Weld Storm - 21 ft. 2006 tips the scales at 345 lbs — 318 lbs less than the Custom Weld 20 ft. Cobra 2013 at 27 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 Custom Weld 20 ft. Cobra 2013 carries a rated maximum of 350 hp. Engine data for the Custom Weld Storm - 21 ft. 2006 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Custom Weld 20 ft. Cobra 2013 carries 52 gallons versus 7 gallons in the Custom Weld Storm - 21 ft. 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

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 Storm - 21 ft. 2006 at 21,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Custom Weld 20 ft. Cobra 2013 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
