When two boats share the same hull type — in this case both the Glastron GLS 255 2009 and the Glastron GT 205 2008 are deep vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Glastron GLS 255 2009 measures 25,0 feet overall (2009), giving it roughly 23,0 additional feet of deck space compared to the Glastron GT 205 2008 at 2,0 feet (2008). Weight tells a clearer story for trailering families: the Glastron GT 205 2008 tips the scales at 278 lbs — 232 lbs less than the Glastron GLS 255 2009 at 46 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 Glastron GT 205 2008 tops out at 270 hp.

On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
