The Glastron DX 235 2008 vs Glastron MX 170 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.
Size is the most obvious dividing line here. The Glastron DX 235 2008 measures 22,0 feet overall (2008), giving it roughly 5,0 additional feet of deck space compared to the Glastron MX 170 2006 at 17,0 feet (2006). Weight tells a clearer story for trailering families: the Glastron DX 235 2008 tips the scales at 4 000 lbs - 2 515 lbs more than the Glastron MX 170 2006 at 1 485 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 320 hp, the Glastron DX 235 2008 has a 170-hp advantage over the Glastron MX 170 2006's 150-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 2008 carries 73 gallons versus 23 gallons in the Glastron MX 170 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 DX 235 2008 is rated for 6 passengers, while the Glastron MX 170 2006 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron DX 235 2008 could be the deciding factor.
Bottom line: Choose the Glastron DX 235 2008 if your priority is putting more people on the water - it handles 6 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The Glastron MX 170 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
