Glastron GS 259 2006 vs Glastron GT 225 2008 — Same Brand, Different Boat

The Glastron GS 259 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.

On paper these two are close siblings in the size department — Glastron GS 259 2006 at 24,0 ft versus Glastron GT 225 2008 at 21,0 ft. Weight tells a clearer story for trailering families: the Glastron GS 259 2006 tips the scales at 5 535 lbs — 5 532 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.

Both boats share a closely matched power ceiling — 320 hp for the Glastron GS 259 2006 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 GS 259 2006 carries 56 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 GS 259 2006 is rated for up to 7 people. Passenger data for the Glastron GT 225 2008 wasn't available.

Bottom line: The Glastron GS 259 2006 at 24,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Glastron GT 225 2008 at 21,0 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.

Glastron GS 259 2006 vs Glastron GT 225 2008 — Common Questions

Which is the larger boat — the Glastron GS 259 2006 or the Glastron GT 225 2008?
The Glastron GS 259 2006 is the longer of the two at 24,0 feet overall. The Glastron GT 225 2008 comes in at 21,0 feet, making it roughly 3,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Glastron GS 259 2006 or the Glastron GT 225 2008?
For trailering, the Glastron GT 225 2008 has the edge at 3 lbs dry weight versus 5 535 lbs for the Glastron GS 259 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.
How many passengers can the Glastron GS 259 2006 carry?

The Glastron GS 259 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.
Which boat has the larger fuel tank — the Glastron GS 259 2006 or the Glastron GT 225 2008?
The Glastron GS 259 2006 has the bigger tank at 56 gallons, versus 35 gallons on the Glastron GT 225 2008. That 21-gallon difference translates to roughly 63–105 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
