The Glastron DX 235 2006 vs Glastron GX 255 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department — Glastron DX 235 2006 at 22,0 ft versus Glastron GX 255 2006 at 25,0 ft. Weight tells a clearer story for trailering families: the Glastron GX 255 2006 tips the scales at 4 685 lbs — 4 681 lbs less than the Glastron DX 235 2006 at 4 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 375 hp, the Glastron GX 255 2006 has a 75-hp advantage over the Glastron DX 235 2006's 300-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Glastron DX 235 2006 carries 73 gallons versus 56 gallons in the Glastron GX 255 2006. 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 GX 255 2006 is rated for 7 passengers, while the Glastron DX 235 2006 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GX 255 2006 could be the deciding factor.
Bottom line: Choose the Glastron GX 255 2006 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 DX 235 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
