Glastron DX 235 2006 vs Glastron GT 180 2008 — Same Brand, Different Boat

The Glastron DX 235 2006 vs Glastron GT 180 2008 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 2006 measures 22,0 feet overall (2006), giving it roughly 5,0 additional feet of deck space compared to the Glastron GT 180 2008 at 17,0 feet (2008). At 4 lbs and 15 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The Glastron DX 235 2006 carries a rated maximum of 300 hp. Engine data for the Glastron GT 180 2008 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Glastron DX 235 2006 carries 73 gallons versus 23 gallons in the Glastron GT 180 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 DX 235 2006 is rated for 6 passengers, while the Glastron GT 180 2008 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 2006 could be the deciding factor.

Bottom line: Choose the Glastron DX 235 2006 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 GT 180 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Glastron DX 235 2006 vs Glastron GT 180 2008 — Common Questions

Which is the larger boat — the Glastron DX 235 2006 or the Glastron GT 180 2008?
The Glastron DX 235 2006 is the longer of the two at 22,0 feet overall. The Glastron GT 180 2008 comes in at 17,0 feet, making it roughly 5,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Glastron DX 235 2006 or the Glastron GT 180 2008?
For trailering, the Glastron DX 235 2006 has the edge at 4 lbs dry weight versus 15 lbs for the Glastron GT 180 2008. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
What is the maximum horsepower rating for these boats?
The Glastron DX 235 2006 has a documented max rating of 300 hp. Engine specifications for the Glastron GT 180 2008 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Glastron DX 235 2006 is Coast Guard rated for 6 passengers, while the Glastron GT 180 2008 is certified for 5. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Glastron DX 235 2006 measures 102" wide, compared to 88" for the Glastron GT 180 2008. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Glastron DX 235 2006 or the Glastron GT 180 2008?
The Glastron DX 235 2006 has the bigger tank at 73 gallons, versus 23 gallons on the Glastron GT 180 2008. That 50-gallon difference translates to roughly 150–250 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Glastron DX 235 2006 and Glastron GT 180 2008 from the same manufacturer?
Yes — both the Glastron DX 235 2006 and the Glastron GT 180 2008 are built by Glastron. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
