When two boats share the same hull type — in this case both the Glastron GT 180 2008 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 GT 180 2008 measures 17,0 feet overall (2008), giving it roughly 15,0 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 — 263 lbs less than the Glastron GT 180 2008 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 Glastron GT 205 2008 tops out at 270 hp.
