The Skeeter SX 190 2007 is a modified-V design and the Skeeter WX 1850 2011 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department - Skeeter SX 190 2007 at 18,0 ft versus Skeeter WX 1850 2011 at 18,8 ft. Weight tells a clearer story for trailering families: the Skeeter WX 1850 2011 tips the scales at 1 800 lbs - 410 lbs less than the Skeeter SX 190 2007 at 1 390 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 SX 190 2007 and 150 hp for the Skeeter WX 1850 2011. 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 WX 1850 2011 carries 40 gallons versus 36 gallons in the Skeeter SX 190 2007. 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 WX 1850 2011 is rated for 6 passengers, while the Skeeter SX 190 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Skeeter WX 1850 2011 could be the deciding factor.
Bottom line: Choose the Skeeter WX 1850 2011 if your priority is putting more people on the water - it handles 6 passengers and at 18,8 ft it has the deck room to back that rating up comfortably. The Skeeter SX 190 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
