When two boats share the same hull type — in this case both the Glastron GT 185 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 GT 185 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 GT 185 Ski & Fish 2008 tips the scales at 2 335 lbs — 850 lbs more than the Glastron MX 170 2008 at 1 485 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 GT 185 Ski & Fish 2008 carries a rated maximum of 135 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.Both carry nearly identical fuel loads — 23 gal and 23 gal — so range won't be a tiebreaker here.
