When two boats share the same hull type — in this case both the Nautique Ski Nautique 216 2009 and the Nautique Super Air Nautique 210 2008 are modified vee designs with fiberglass 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 — Nautique Ski Nautique 216 2009 at 21,0 ft versus Nautique Super Air Nautique 210 2008 at 21,0 ft. Weight tells a clearer story for trailering families: the Nautique Ski Nautique 216 2009 tips the scales at 299 lbs — 261 lbs more than the Nautique Super Air Nautique 210 2008 at 38 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 — 409 hp for the Nautique Ski Nautique 216 2009 and 390 hp for the Nautique Super Air Nautique 210 2008. 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. Fuel capacity breaks the other way: the Nautique Ski Nautique 216 2009 carries 29 gallons versus 4 gallons in the Nautique Super Air Nautique 210 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 1 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 Nautique Ski Nautique 216 2009 and its 409-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Nautique Super Air Nautique 210 2008 with its 390-hp rating is the more economical daily driver.
