Both the Glastron GT 180 2013 and the Glastron MX 205 2013 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?

On paper these two are close siblings in the size department - Glastron GT 180 2013 at 17,8 ft versus Glastron MX 205 2013 at 20,7 ft. Weight tells a clearer story for trailering families: the Glastron MX 205 2013 tips the scales at 2 750 lbs - 650 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 MX 205 2013 is rated for 9 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 MX 205 2013 could be the deciding factor.
