When two boats share the same hull type — in this case both the Glastron GS 219 2008 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 GXL 255 2008 measures 25,0 feet overall (2008), giving it roughly 4,0 additional feet of deck space compared to the Glastron GS 219 2008 at 21,0 feet (2008). Weight tells a clearer story for trailering families: the Glastron GXL 255 2008 tips the scales at 4 675 lbs — 4 317 lbs less than the Glastron GS 219 2008 at 358 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 219 2008'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 GXL 255 2008 is rated for 7 passengers, while the Glastron GS 219 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 GXL 255 2008 could be the deciding factor.
Bottom line: Choose the Glastron GXL 255 2008 if your priority is putting more people on the water — it handles 7 passengers and at 25,0 ft it has the deck room to back that rating up comfortably. The Glastron GS 219 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
