When two boats share the same hull type — in this case both the Glastron GS 289 SC 2010 and the Glastron GXL 255 2008 are deep vee designs with fiberglass construction — 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 289 SC 2010 measures 30,3 feet overall (2010), giving it roughly 5,3 additional feet of deck space compared to the Glastron GXL 255 2008 at 25,0 feet (2008). Weight tells a clearer story for trailering families: the Glastron GXL 255 2008 tips the scales at 4 675 lbs — 4 610 lbs less than the Glastron GS 289 SC 2010 at 65 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 Glastron GXL 255 2008 tops out at 425 hp. Engine specs for the Glastron GS 289 SC 2010 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Glastron GS 289 SC 2010 carries 84 gallons versus 56 gallons in the Glastron GXL 255 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 289 SC 2010 is rated for 8 passengers, while the Glastron GXL 255 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 GS 289 SC 2010 could be the deciding factor.
