Custom Weld Storm - 21 ft. 2009 vs Custom Weld X-Caliber 2013 — Same Brand, Different Boat

The Custom Weld Storm - 21 ft. 2009 vs Custom Weld X-Caliber 2013 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.

On paper these two are close siblings in the size department — Custom Weld Storm - 21 ft. 2009 at 21,0 ft versus Custom Weld X-Caliber 2013 at 21,0 ft. Weight tells a clearer story for trailering families: the Custom Weld Storm - 21 ft. 2009 tips the scales at 345 lbs — 317 lbs more than the Custom Weld X-Caliber 2013 at 28 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.

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. 2009 and Custom Weld X-Caliber 2013 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.

The Custom Weld X-Caliber 2013 is the longer of the two at 21,0 feet overall. The Custom Weld Storm - 21 ft. 2009 comes in at 21,0 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

For trailering, the Custom Weld X-Caliber 2013 has the edge at 28 lbs dry weight versus 345 lbs for the Custom Weld Storm - 21 ft. 2009.

The Custom Weld Storm - 21 ft. 2009 is Coast Guard rated for 6 passengers, while the Custom Weld X-Caliber 2013 is certified for 6.

Both the Custom Weld Storm - 21 ft. 2009 and Custom Weld X-Caliber 2013 share an 96 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
How do the fuel tanks compare on the Custom Weld Storm - 21 ft. 2009 and Custom Weld X-Caliber 2013?

Yes — both the Custom Weld Storm - 21 ft. 2009 and the Custom Weld X-Caliber 2013 are built by Custom Weld.
