When two boats share the same hull type — in this case both the Nautique Byerly 210 2010 and the Nautique Super Air Nautique 210 2007 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 Byerly 210 2010 at 21,0 ft versus Nautique Super Air Nautique 210 2007 at 21,0 ft. At 38 lbs and 38 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.
The Nautique Byerly 210 2010 carries a rated maximum of 343 hp. Engine data for the Nautique Super Air Nautique 210 2007 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Nautique Super Air Nautique 210 2007 carries 39 gallons versus 4 gallons in the Nautique Byerly 210 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Nautique Byerly 210 2010 is rated for 12 passengers, while the Nautique Super Air Nautique 210 2007 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Nautique Byerly 210 2010 could be the deciding factor.
Bottom line: Choose the Nautique Byerly 210 2010 if your priority is putting more people on the water — it handles 12 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Nautique Super Air Nautique 210 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
