When two boats share the same hull type — in this case both the Glastron GXL 180 Ski & Fish 2008 and the Glastron MX 170 2008 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 GXL 180 Ski & Fish 2008 at 18,0 ft versus Glastron MX 170 2008 at 17,0 ft. Weight tells a clearer story for trailering families: the Glastron MX 170 2008 tips the scales at 1 485 lbs — 1 313 lbs less than the Glastron GXL 180 Ski & Fish 2008 at 172 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 GXL 180 Ski & Fish 2008 carries a rated maximum of 150 hp. Engine data for the Glastron MX 170 2008 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Glastron GXL 180 Ski & Fish 2008 carries 29 gallons versus 23 gallons in the Glastron MX 170 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
