When two boats share the same hull type — in this case both the Glastron GTS 205 2013 and the Glastron MX 180 2012 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 GTS 205 2013 measures 20,5 feet overall (2013), giving it roughly 3,4 additional feet of deck space compared to the Glastron MX 180 2012 at 17,1 feet (2012). Weight tells a clearer story for trailering families: the Glastron GTS 205 2013 tips the scales at 277 lbs — 262 lbs more than the Glastron MX 180 2012 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 MX 180 2012 tops out at 150 hp. Engine specs for the Glastron GTS 205 2013 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Glastron GTS 205 2013 carries 32 gallons versus 24 gallons in the Glastron MX 180 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Glastron GTS 205 2013 is rated for 9 passengers, while the Glastron MX 180 2012 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GTS 205 2013 could be the deciding factor.
