Both the Glastron GT 185 Ski & Fish 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 GT 185 Ski & Fish 2008 at 18,0 ft versus Glastron MX 185 2011 at 17,1 ft. At 2 335 lbs and 2 280 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 220 hp, the Glastron MX 185 2011 has a 85-hp advantage over the Glastron GT 185 Ski & Fish 2008's 135-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 23 gal - so range won't be a tiebreaker here.

At this size, power-to-weight ratio matters more than outright horsepower. The Glastron MX 185 2011 comes in at 10 lbs per hp versus 17 lbs per hp for the Glastron GT 185 Ski & Fish 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.
