Glastron DX 205 2006 vs Glastron GT 225 2008 - Boat Spec Comparison

Q: Which is the larger boat — the Glastron DX 205 2006 or the Glastron GT 225 2008?

The Glastron GT 225 2008 is the longer of the two at 21,0 feet overall. The Glastron DX 205 2006 comes in at 2,0 feet, making it roughly 19,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer — the Glastron DX 205 2006 or the Glastron GT 225 2008?

For trailering, the Glastron GT 225 2008 has the edge at 3 lbs dry weight versus 2 937 lbs for the Glastron DX 205 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.

Q: 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 205 2006 tops out at 270 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.

Q: How many passengers can the Glastron DX 205 2006 carry?

The Glastron DX 205 2006 has an official capacity rating of 6 people. Capacity data wasn't available for the other model in this comparison — verify directly with the dealer.

Q: Which boat is wider, and does it affect trailering?

The Glastron DX 205 2006 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.

Q: Which boat has the larger fuel tank — the Glastron DX 205 2006 or the Glastron GT 225 2008?

The Glastron GT 225 2008 has the bigger tank at 35 gallons, versus 5 gallons on the Glastron DX 205 2006. That 30-gallon difference translates to roughly 90–150 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Glastron DX 205 2006 and Glastron GT 225 2008 from the same manufacturer?

Yes — both the Glastron DX 205 2006 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.

Detailed Evaluation & Buyer Recommendation

Glastron DX 205 2006 vs Glastron GT 225 2008 — Same Brand, Different Boat

The Glastron DX 205 2006 vs Glastron GT 225 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 GT 225 2008 measures 21,0 feet overall (2008), giving it roughly 19,0 additional feet of deck space compared to the Glastron DX 205 2006 at 2,0 feet (2006). Weight tells a clearer story for trailering families: the Glastron DX 205 2006 tips the scales at 2 937 lbs — 2 934 lbs more than the Glastron GT 225 2008 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 320 hp, the Glastron GT 225 2008 has a 50-hp advantage over the Glastron DX 205 2006's 270-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 2008 carries 35 gallons versus 5 gallons in the Glastron DX 205 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Glastron DX 205 2006 is rated for up to 6 people. Passenger data for the Glastron GT 225 2008 wasn't available.

Bottom line: The Glastron GT 225 2008 at 21,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Glastron DX 205 2006 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
