The Skeeter WX 2100 2008 is a deep-V design and the Skeeter ZX 190 2007 is a modified-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 WX 2100 2008 at 21,0 ft versus Skeeter ZX 190 2007 at 18,0 ft. Weight tells a clearer story for trailering families: the Skeeter WX 2100 2008 tips the scales at 1 950 lbs - 450 lbs more than the Skeeter ZX 190 2007 at 1 500 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.
The power gap is worth calling out. Rated to 300 hp, the Skeeter WX 2100 2008 has a 125-hp advantage over the Skeeter ZX 190 2007's 175-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Skeeter WX 2100 2008 carries 64 gallons versus 36 gallons in the Skeeter ZX 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 2100 2008 is rated for 7 passengers, while the Skeeter ZX 190 2007 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Skeeter WX 2100 2008 could be the deciding factor.
Bottom line: Choose the Skeeter WX 2100 2008 if your priority is putting more people on the water - it handles 7 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Skeeter ZX 190 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
