Glastron GT 205 2012 vs Glastron GX 185 Ski & Fish 2006 — Same Brand, Different Boat

The Glastron GT 205 2012 vs Glastron GX 185 Ski & Fish 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 205 2012 at 20,7 ft versus Glastron GX 185 Ski & Fish 2006 at 18,0 ft. At 275 lbs and 276 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.

The power gap is worth calling out. Rated to 270 hp, the Glastron GT 205 2012 has a 45-hp advantage over the Glastron GX 185 Ski & Fish 2006's 225-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 205 2012 carries 34 gallons versus 29 gallons in the Glastron GX 185 Ski & Fish 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 205 2012 is rated for 9 passengers, while the Glastron GX 185 Ski & Fish 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 205 2012 could be the deciding factor.

Bottom line: Choose the Glastron GT 205 2012 if your priority is putting more people on the water — it handles 9 passengers and at 20,7 ft it has the deck room to back that rating up comfortably. The Glastron GX 185 Ski & Fish 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 205 2012 vs Glastron GX 185 Ski & Fish 2006 — Common Questions

Which is the larger boat — the Glastron GT 205 2012 or the Glastron GX 185 Ski & Fish 2006?
The Glastron GT 205 2012 is the longer of the two at 20,7 feet overall. The Glastron GX 185 Ski & Fish 2006 comes in at 18,0 feet, making it roughly 2,7 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Glastron GT 205 2012 or the Glastron GX 185 Ski & Fish 2006?
For trailering, the Glastron GT 205 2012 has the edge at 275 lbs dry weight versus 276 lbs for the Glastron GX 185 Ski & Fish 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 205 2012 is rated to a maximum of 270 hp, giving it the larger power ceiling. The Glastron GX 185 Ski & Fish 2006 tops out at 225 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 205 2012 is Coast Guard rated for 9 passengers, while the Glastron GX 185 Ski & Fish 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 205 2012 measures 92" wide, compared to 91" for the Glastron GX 185 Ski & Fish 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 205 2012 or the Glastron GX 185 Ski & Fish 2006?
The Glastron GT 205 2012 has the bigger tank at 34 gallons, versus 29 gallons on the Glastron GX 185 Ski & Fish 2006. That 5-gallon difference translates to roughly 15–25 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Glastron GT 205 2012 and Glastron GX 185 Ski & Fish 2006 from the same manufacturer?
Yes — both the Glastron GT 205 2012 and the Glastron GX 185 Ski & Fish 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.
