Both the Skeeter SL 1900 2009 and the Skeeter ZX 20 Bay 2009 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 1900 2009 at 19,0 ft versus Skeeter ZX 20 Bay 2009 at 19,0 ft. Weight tells a clearer story for trailering families: the Skeeter SL 1900 2009 tips the scales at 1 975 lbs - 225 lbs more than the Skeeter ZX 20 Bay 2009 at 1 750 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 2009 has a 50-hp advantage over the Skeeter ZX 20 Bay 2009'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 ZX 20 Bay 2009 carries 45 gallons versus 30 gallons in the Skeeter SL 1900 2009. 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 SL 1900 2009 is rated for 6 passengers, while the Skeeter ZX 20 Bay 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Skeeter SL 1900 2009 could be the deciding factor.
Bottom line: Choose the Skeeter SL 1900 2009 if your priority is putting more people on the water - it handles 6 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Skeeter ZX 20 Bay 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
