When two boats share the same hull type — in this case both the Sundance DX20 2012 and the Sundance DX22 2012 are modified vee designs with composite construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department — Sundance DX20 2012 at 19,8 ft versus Sundance DX22 2012 at 21,8 ft. Weight tells a clearer story for trailering families: the Sundance DX22 2012 tips the scales at 1 685 lbs — 110 lbs less than the Sundance DX20 2012 at 1 575 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 share a closely matched power ceiling — 130 hp for the Sundance DX20 2012 and 150 hp for the Sundance DX22 2012. 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 — 33 gal and 33 gal — so range won't be a tiebreaker here.
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 Sundance DX22 2012 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sundance DX20 2012 with its 130-hp rating is the more economical daily driver.
