The Skeeter SL 1900 2012 is a modified-V design and the Skeeter WX 1790 T 2009 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 SL 1900 2012 at 19,0 ft versus Skeeter WX 1790 T 2009 at 17,0 ft. Weight tells a clearer story for trailering families: the Skeeter SL 1900 2012 tips the scales at 1 975 lbs - 675 lbs more than the Skeeter WX 1790 T 2009 at 1 300 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 200 hp, the Skeeter SL 1900 2012 has a 120-hp advantage over the Skeeter WX 1790 T 2009's 80-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 30 gal and 33 gal - so range won't be a tiebreaker here.
Both boats are rated for 6 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: Performance buyers should lean toward the Skeeter SL 1900 2012 and its 200-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Skeeter WX 1790 T 2009 with its 80-hp rating is the more economical daily driver.
