Glastron DX 235 2011 vs Glastron GT 225 2008: Same Brand, Different Boat

The Glastron DX 235 2011 is a modified-V design and the Glastron GT 225 2008 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department - Glastron DX 235 2011 at 22,5 ft versus Glastron GT 225 2008 at 21,0 ft. Weight tells a clearer story for trailering families: the Glastron DX 235 2011 tips the scales at 4 000 lbs - 1 000 lbs more than the Glastron GT 225 2008 at 3 000 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.

Both boats share a closely matched power ceiling - 300 hp for the Glastron DX 235 2011 and 320 hp for the Glastron GT 225 2008. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Glastron DX 235 2011 carries 73 gallons versus 35 gallons in the Glastron GT 225 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Glastron DX 235 2011 is rated for up to 13 people. Passenger data for the Glastron GT 225 2008 wasn't available.

Bottom line: Performance buyers should lean toward the Glastron GT 225 2008 and its 320-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Glastron DX 235 2011 with its 300-hp rating is the more economical daily driver.

Glastron DX 235 2011 vs Glastron GT 225 2008 - Common Questions

Which is the larger boat - the Glastron DX 235 2011 or the Glastron GT 225 2008?
The Glastron DX 235 2011 is the longer of the two at 22,5 feet overall. The Glastron GT 225 2008 comes in at 21,0 feet, making it roughly 1,5 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Glastron DX 235 2011 or the Glastron GT 225 2008?
For trailering, the Glastron GT 225 2008 has the edge at 3 000 lbs dry weight versus 4 000 lbs for the Glastron DX 235 2011. 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.
Which boat can handle a bigger outboard?
The Glastron GT 225 2008 is rated to a maximum of 320 hp, giving it the larger power ceiling. The Glastron DX 235 2011 tops out at 300 hp. Keep in mind that maximum ratings are just that - matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many passengers can the Glastron DX 235 2011 carry?
The Glastron DX 235 2011 has an official capacity rating of 13 people. Capacity data wasn't available for the other model in this comparison - verify directly with the dealer.
Which boat is wider, and does it affect trailering?
The Glastron DX 235 2011 measures 102" wide, compared to 99" for the Glastron GT 225 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 2011 or the Glastron GT 225 2008?
The Glastron DX 235 2011 has the bigger tank at 73 gallons, versus 35 gallons on the Glastron GT 225 2008. That 38-gallon difference translates to roughly 114–190 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Glastron DX 235 2011 and Glastron GT 225 2008 from the same manufacturer?
Yes - both the Glastron DX 235 2011 and the Glastron GT 225 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.
