When two boats share the same hull type — in this case both the Glastron GS 209 2012 and the Glastron MX 205 2013 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?

On paper these two are close siblings in the size department — Glastron GS 209 2012 at 20,2 ft versus Glastron MX 205 2013 at 20,7 ft. Weight tells a clearer story for trailering families: the Glastron GS 209 2012 tips the scales at 2 832 lbs — 2 557 lbs more than the Glastron MX 205 2013 at 275 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 GS 209 2012 carries a rated maximum of 270 hp. Engine data for the Glastron MX 205 2013 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Glastron GS 209 2012 carries 45 gallons versus 34 gallons in the Glastron MX 205 2013. 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 MX 205 2013 is rated for 9 passengers, while the Glastron GS 209 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 MX 205 2013 could be the deciding factor.
