Both the Glastron GLS 235 2011 and the Glastron GXL 235 2008 are deep-V designs, both built in fibreglass, 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 - Glastron GLS 235 2011 at 23,8 ft versus Glastron GXL 235 2008 at 23,0 ft. Weight tells a clearer story for trailering families: the Glastron GLS 235 2011 tips the scales at 4 080 lbs - 205 lbs more than the Glastron GXL 235 2008 at 3 875 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 - 300 hp for the Glastron GLS 235 2011 and 320 hp for the Glastron GXL 235 2008. 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 Glastron GLS 235 2011 carries 56 gallons versus 47 gallons in the Glastron GXL 235 2008. 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 Glastron GLS 235 2011 is rated for 12 passengers, while the Glastron GXL 235 2008 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GLS 235 2011 could be the deciding factor.
