Glastron GT 225 2011 vs Glastron GX 180 2006 — Same Brand, Different Boat

The Glastron GT 225 2011 vs Glastron GX 180 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 GT 225 2011 at 20,1 ft versus Glastron GX 180 2006 at 18,0 ft. Weight tells a clearer story for trailering families: the Glastron GX 180 2006 tips the scales at 171 lbs — 168 lbs less than the Glastron GT 225 2011 at 3 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 300 hp, the Glastron GT 225 2011 has a 150-hp advantage over the Glastron GX 180 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 GT 225 2011 carries 35 gallons versus 29 gallons in the Glastron GX 180 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 GT 225 2011 is rated for 10 passengers, while the Glastron GX 180 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 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 GX 180 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.

Glastron GT 225 2011 vs Glastron GX 180 2006 — Common Questions

Which is the larger boat — the Glastron GT 225 2011 or the Glastron GX 180 2006?
The Glastron GT 225 2011 is the longer of the two at 20,1 feet overall. The Glastron GX 180 2006 comes in at 18,0 feet, making it roughly 2,1 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Glastron GT 225 2011 or the Glastron GX 180 2006?
For trailering, the Glastron GT 225 2011 has the edge at 3 lbs dry weight versus 171 lbs for the Glastron GX 180 2006. 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 2011 is rated to a maximum of 300 hp, giving it the larger power ceiling. The Glastron GX 180 2006 tops out at 150 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 GT 225 2011 is Coast Guard rated for 10 passengers, while the Glastron GX 180 2006 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 GT 225 2011 measures 100" wide, compared to 91" for the Glastron GX 180 2006. 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 GT 225 2011 or the Glastron GX 180 2006?
The Glastron GT 225 2011 has the bigger tank at 35 gallons, versus 29 gallons on the Glastron GX 180 2006. That 6-gallon difference translates to roughly 18–30 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Glastron GT 225 2011 and Glastron GX 180 2006 from the same manufacturer?
Yes — both the Glastron GT 225 2011 and the Glastron GX 180 2006 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.
