Both the Glastron GLS 215 2009 and the Glastron GT 180 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 GLS 215 2009 measures 21,0 feet overall (2009), giving it roughly 4,0 additional feet of deck space compared to the Glastron GT 180 2009 at 17,0 feet (2009). Weight tells a clearer story for trailering families: the Glastron GLS 215 2009 tips the scales at 3 330 lbs - 1 830 lbs more than the Glastron GT 180 2009 at 1 500 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 GLS 215 2009 is rated for 10 passengers, while the Glastron GT 180 2009 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GLS 215 2009 could be the deciding factor.
