Both the Glastron GT 185 2008 and the Glastron MX 180 2012 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 GT 185 2008 at 18,0 ft versus Glastron MX 180 2012 at 17,1 ft. Weight tells a clearer story for trailering families: the Glastron GT 185 2008 tips the scales at 2 315 lbs - 815 lbs more than the Glastron MX 180 2012 at 1 500 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 190 hp, the Glastron GT 185 2008 has a 40-hp advantage over the Glastron MX 180 2012's 150-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 23 gal and 24 gal - so range won't be a tiebreaker here.

At this size, power-to-weight ratio matters more than outright horsepower. The Glastron MX 180 2012 comes in at 10 lbs per hp versus 12 lbs per hp for the Glastron GT 185 2008. The lower the ratio the more explosive the acceleration - meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
