Both the Glastron GS 279 2008 and the Glastron GXL 205 Ski & Fish 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?

Size is the most obvious dividing line here. The Glastron GS 279 2008 measures 27,0 feet overall (2008), giving it roughly 8,0 additional feet of deck space compared to the Glastron GXL 205 Ski & Fish 2008 at 19,0 feet (2008). Weight tells a clearer story for trailering families: the Glastron GS 279 2008 tips the scales at 6 225 lbs - 3 150 lbs more than the Glastron GXL 205 Ski & Fish 2008 at 3 075 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 - 320 hp for the Glastron GS 279 2008 and 300 hp for the Glastron GXL 205 Ski & Fish 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 GS 279 2008 carries 72 gallons versus 35 gallons in the Glastron GXL 205 Ski & Fish 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 GS 279 2008 is rated for 8 passengers, while the Glastron GXL 205 Ski & Fish 2008 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GS 279 2008 could be the deciding factor.
