Both the Glastron GT 180 2013 and the Glastron GT 225 2009 are deep-V designs, both built in fibreglass, so 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 225 2009 measures 21,0 feet overall (2009), giving it roughly 3,2 additional feet of deck space compared to the Glastron GT 180 2013 at 17,8 feet (2013). Weight tells a clearer story for trailering families: the Glastron GT 225 2009 tips the scales at 3 000 lbs - 900 lbs less than the Glastron GT 180 2013 at 2 100 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.

For family outings this is probably the sharpest distinction between the two. The Glastron GT 225 2009 is rated for 10 passengers, while the Glastron GT 180 2013 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GT 225 2009 could be the deciding factor.
