Glastron GS 259 2012 vs Glastron GX 235 2005: Same Brand, Different Boat

The Glastron GS 259 2012 vs Glastron GX 235 2005 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.

The power gap is worth calling out. Rated to 300 hp, the Glastron GS 259 2012 has a 30-hp advantage over the Glastron GX 235 2005'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 GS 259 2012 carries 56 gallons versus 47 gallons in the Glastron GX 235 2005. 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 GS 259 2012 is rated for 10 passengers, while the Glastron GX 235 2005 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GS 259 2012 could be the deciding factor.

Bottom line: Choose the Glastron GS 259 2012 if your priority is putting more people on the water - it handles 10 passengers and at 24,8 ft it has the deck room to back that rating up comfortably. The Glastron GX 235 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.

Glastron GS 259 2012 vs Glastron GX 235 2005 - Common Questions

Which is the larger boat - the Glastron GS 259 2012 or the Glastron GX 235 2005?
The Glastron GS 259 2012 is the longer of the two at 24,8 feet overall. The Glastron GX 235 2005 comes in at 23,0 feet, making it roughly 1,8 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Glastron GS 259 2012 is rated to a maximum of 300 hp, giving it the larger power ceiling. The Glastron GX 235 2005 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.
How many people can each boat hold?
The Glastron GS 259 2012 is Coast Guard rated for 10 passengers, while the Glastron GX 235 2005 is certified for 7. 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 has the larger fuel tank - the Glastron GS 259 2012 or the Glastron GX 235 2005?
The Glastron GS 259 2012 has the bigger tank at 56 gallons, versus 47 gallons on the Glastron GX 235 2005. That 9-gallon difference translates to roughly 27–45 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Glastron GS 259 2012 and Glastron GX 235 2005 from the same manufacturer?
Yes - both the Glastron GS 259 2012 and the Glastron GX 235 2005 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.
