Both the Skeeter 21i 2013 and the Skeeter SX 190 2008 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 21i 2013 at 21,0 ft versus Skeeter SX 190 2008 at 18,0 ft. Weight tells a clearer story for trailering families: the Skeeter 21i 2013 tips the scales at 2 250 lbs - 860 lbs more than the Skeeter SX 190 2008 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.
The power gap is worth calling out. Rated to 300 hp, the Skeeter 21i 2013 has a 150-hp advantage over the Skeeter SX 190 2008's 150-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 21i 2013 carries 50 gallons versus 36 gallons in the Skeeter SX 190 2008. 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 21i 2013 at 21,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Skeeter SX 190 2008 at 18,0 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.
