The Glasstream 17 Flats Flite 2010 is a flat-bottom design and the Glasstream 328 Pro-X 2011 is a modified-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.

Size is the most obvious dividing line here. The Glasstream 328 Pro-X 2011 measures 32,0 feet overall (2011), giving it roughly 15,2 additional feet of deck space compared to the Glasstream 17 Flats Flite 2010 at 16,8 feet (2010). Weight tells a clearer story for trailering families: the Glasstream 328 Pro-X 2011 tips the scales at 5 300 lbs - 4 125 lbs less than the Glasstream 17 Flats Flite 2010 at 1 175 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 700 hp, the Glasstream 328 Pro-X 2011 has a 640-hp advantage over the Glasstream 17 Flats Flite 2010's 60-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Glasstream 328 Pro-X 2011 carries 300 gallons versus 25 gallons in the Glasstream 17 Flats Flite 2010. 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 Glasstream 328 Pro-X 2011 is rated for 9 passengers, while the Glasstream 17 Flats Flite 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glasstream 328 Pro-X 2011 could be the deciding factor.
