Both the Glastron GXL 205 2008 and the Glastron MX 185 2011 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 GXL 205 2008 at 19,0 ft versus Glastron MX 185 2011 at 17,1 ft. Weight tells a clearer story for trailering families: the Glastron GXL 205 2008 tips the scales at 3 025 lbs - 745 lbs more than the Glastron MX 185 2011 at 2 280 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 power gap is worth calling out. Rated to 320 hp, the Glastron GXL 205 2008 has a 100-hp advantage over the Glastron MX 185 2011's 220-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Glastron GXL 205 2008 carries 35 gallons versus 23 gallons in the Glastron MX 185 2011. 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 185 2011 is rated for 7 passengers, while the Glastron GXL 205 2008 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron MX 185 2011 could be the deciding factor.
