Both the Skeeter SL 180 2007 and the Skeeter ZX 20 Bay 2010 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 SL 180 2007 at 17,0 ft versus Skeeter ZX 20 Bay 2010 at 19,7 ft. Weight tells a clearer story for trailering families: the Skeeter ZX 20 Bay 2010 tips the scales at 1 750 lbs - 370 lbs less than the Skeeter SL 180 2007 at 1 380 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 - 150 hp for the Skeeter SL 180 2007 and 150 hp for the Skeeter ZX 20 Bay 2010. 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 20 Bay 2010 carries 45 gallons versus 30 gallons in the Skeeter SL 180 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 5 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 Skeeter ZX 20 Bay 2010 at 19,7 ft is the right call if deck space, comfort, and entertaining are top of your list. The Skeeter SL 180 2007 at 17,0 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.
