The Glastron DS 205 2011 is a modified-V design and the Glastron GT 205 SF 2011 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department - Glastron DS 205 2011 at 20,1 ft versus Glastron GT 205 SF 2011 at 19,3 ft. Weight tells a clearer story for trailering families: the Glastron DS 205 2011 tips the scales at 2 900 lbs - 150 lbs more than the Glastron GT 205 SF 2011 at 2 750 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 - 270 hp for the Glastron DS 205 2011 and 270 hp for the Glastron GT 205 SF 2011. 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 DS 205 2011 carries 50 gallons versus 35 gallons in the Glastron GT 205 SF 2011. 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 DS 205 2011 is rated for 10 passengers, while the Glastron GT 205 SF 2011 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron DS 205 2011 could be the deciding factor.
