The Glastron GT 205 2011 vs Glastron SX 170 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.

Size is the most obvious dividing line here. The Glastron GT 205 2011 measures 20,7 feet overall (2011), giving it roughly 3,7 additional feet of deck space compared to the Glastron SX 170 2006 at 17,0 feet (2006). Weight tells a clearer story for trailering families: the Glastron GT 205 2011 tips the scales at 275 lbs — 260 lbs more than the Glastron SX 170 2006 at 15 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 270 hp, the Glastron GT 205 2011 has a 120-hp advantage over the Glastron SX 170 2006's 150-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 2011 carries 35 gallons versus 23 gallons in the Glastron SX 170 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 2011 is rated for 9 passengers, while the Glastron SX 170 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 2011 could be the deciding factor.
