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

Matching a modified vee Glastron DX 235 2008 against a deep vee Glastron GT 225 2011 means you're likely deciding between two genuinely 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 2008 at 22,0 ft versus Glastron GT 225 2011 at 20,1 ft. At 4 lbs and 3 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.

Both boats share a closely matched power ceiling — 320 hp for the Glastron DX 235 2008 and 300 hp for the Glastron GT 225 2011. 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 2008 carries 73 gallons versus 35 gallons in the Glastron GT 225 2011. 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 GT 225 2011 is rated for 10 passengers, while the Glastron DX 235 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 GT 225 2011 could be the deciding factor.

Bottom line: Choose the Glastron GT 225 2011 if your priority is putting more people on the water — it handles 10 passengers and at 20,1 ft it has the deck room to back that rating up comfortably. The Glastron DX 235 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.

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

Which is the larger boat — the Glastron DX 235 2008 or the Glastron GT 225 2011?
The Glastron DX 235 2008 is the longer of the two at 22,0 feet overall. The Glastron GT 225 2011 comes in at 20,1 feet, making it roughly 1,9 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Glastron DX 235 2008 or the Glastron GT 225 2011?
For trailering, the Glastron GT 225 2011 has the edge at 3 lbs dry weight versus 4 lbs for the Glastron DX 235 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.
Which boat can handle a bigger outboard?
The Glastron DX 235 2008 is rated to a maximum of 320 hp, giving it the larger power ceiling. The Glastron GT 225 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 people can each boat hold?
The Glastron DX 235 2008 is Coast Guard rated for 6 passengers, while the Glastron GT 225 2011 is certified for 10. 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 2008 measures 102" wide, compared to 100" for the Glastron GT 225 2011. 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 2008 or the Glastron GT 225 2011?
The Glastron DX 235 2008 has the bigger tank at 73 gallons, versus 35 gallons on the Glastron GT 225 2011. 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 2008 and Glastron GT 225 2011 from the same manufacturer?
Yes — both the Glastron DX 235 2008 and the Glastron GT 225 2011 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.
