When two boats share the same hull type — in this case both the Glastron GLS 195 2011 and the Glastron MX 175 2009 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 GLS 195 2011 at 19,3 ft versus Glastron MX 175 2009 at 17,0 ft. Weight tells a clearer story for trailering families: the Glastron GLS 195 2011 tips the scales at 2 915 lbs — 2 687 lbs more than the Glastron MX 175 2009 at 228 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 GLS 195 2011 carries a rated maximum of 270 hp. Engine data for the Glastron MX 175 2009 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Glastron GLS 195 2011 carries 34 gallons versus 23 gallons in the Glastron MX 175 2009. 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 GLS 195 2011 is rated for 9 passengers, while the Glastron MX 175 2009 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GLS 195 2011 could be the deciding factor.
