Both the Skeeter 20i 2010 and the Skeeter ZX 22 Bay 2009 are modified-V designs, both built in composite, so 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 - Skeeter 20i 2010 at 20,2 ft versus Skeeter ZX 22 Bay 2009 at 21,0 ft. At 1 850 lbs and 1 850 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.
Both boats share a closely matched power ceiling - 250 hp for the Skeeter 20i 2010 and 250 hp for the Skeeter ZX 22 Bay 2009. 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 Skeeter ZX 22 Bay 2009 carries 60 gallons versus 50 gallons in the Skeeter 20i 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 Skeeter ZX 22 Bay 2009 is rated for 8 passengers, while the Skeeter 20i 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Skeeter ZX 22 Bay 2009 could be the deciding factor.
Bottom line: Choose the Skeeter ZX 22 Bay 2009 if your priority is putting more people on the water - it handles 8 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Skeeter 20i 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
