The Glastron DS 215 2008 is a modified-V design and the Glastron GLS 215 2012 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 215 2008 at 20,0 ft versus Glastron GLS 215 2012 at 21,3 ft. Weight tells a clearer story for trailering families: the Glastron DS 215 2008 tips the scales at 3 630 lbs - 300 lbs more than the Glastron GLS 215 2012 at 3 330 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 - 300 hp for the Glastron DS 215 2008 and 300 hp for the Glastron GLS 215 2012. 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 215 2008 carries 56 gallons versus 40 gallons in the Glastron GLS 215 2012. 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 GLS 215 2012 is rated for 10 passengers, while the Glastron DS 215 2008 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GLS 215 2012 could be the deciding factor.
