Glastron GS 279 2006 vs Glastron GT 185 SF 2012 — Same Brand, Different Boat

The Glastron GS 279 2006 vs Glastron GT 185 SF 2012 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 GS 279 2006 measures 27,0 feet overall (2006), giving it roughly 8,6 additional feet of deck space compared to the Glastron GT 185 SF 2012 at 18,4 feet (2012). Weight tells a clearer story for trailering families: the Glastron GT 185 SF 2012 tips the scales at 2 335 lbs — 2 273 lbs less than the Glastron GS 279 2006 at 62 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 GS 279 2006 has a 100-hp advantage over the Glastron GT 185 SF 2012's 220-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 279 2006 carries 72 gallons versus 24 gallons in the Glastron GT 185 SF 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 8 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Glastron GS 279 2006 at 27,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Glastron GT 185 SF 2012 at 18,4 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 279 2006 vs Glastron GT 185 SF 2012 — Common Questions

Which is the larger boat — the Glastron GS 279 2006 or the Glastron GT 185 SF 2012?
The Glastron GS 279 2006 is the longer of the two at 27,0 feet overall. The Glastron GT 185 SF 2012 comes in at 18,4 feet, making it roughly 8,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Glastron GS 279 2006 or the Glastron GT 185 SF 2012?
For trailering, the Glastron GS 279 2006 has the edge at 62 lbs dry weight versus 2 335 lbs for the Glastron GT 185 SF 2012. 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 GS 279 2006 is rated to a maximum of 320 hp, giving it the larger power ceiling. The Glastron GT 185 SF 2012 tops out at 220 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 279 2006 is Coast Guard rated for 8 passengers, while the Glastron GT 185 SF 2012 is certified for 8. 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 GS 279 2006 measures 102" wide, compared to 88" for the Glastron GT 185 SF 2012. 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 279 2006 or the Glastron GT 185 SF 2012?
The Glastron GS 279 2006 has the bigger tank at 72 gallons, versus 24 gallons on the Glastron GT 185 SF 2012. That 48-gallon difference translates to roughly 144–240 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Glastron GS 279 2006 and Glastron GT 185 SF 2012 from the same manufacturer?
Yes — both the Glastron GS 279 2006 and the Glastron GT 185 SF 2012 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.
