When two boats share the same hull type — in this case both the Glastron GS 259 SC 2011 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?

On paper these two are close siblings in the size department — Glastron GS 259 SC 2011 at 24,8 ft versus Glastron GXL 255 2008 at 25,0 ft. Weight tells a clearer story for trailering families: the Glastron GXL 255 2008 tips the scales at 4 675 lbs — 4 130 lbs less than the Glastron GS 259 SC 2011 at 545 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 425 hp, the Glastron GXL 255 2008 has a 125-hp advantage over the Glastron GS 259 SC 2011's 300-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 56 gal and 56 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Glastron GS 259 SC 2011 is rated for 10 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 259 SC 2011 could be the deciding factor.
