When two boats share the same hull type — in this case both the Glastron GT 185 2009 and the Glastron MX 185 2011 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 2009 at 18,0 ft versus Glastron MX 185 2011 at 17,1 ft. Weight tells a clearer story for trailering families: the Glastron GT 185 2009 tips the scales at 2 315 lbs — 2 087 lbs more than the Glastron MX 185 2011 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 MX 185 2011 tops out at 220 hp. Engine specs for the Glastron GT 185 2009 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 23 gal and 23 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Glastron GT 185 2009 is rated for 8 passengers, while the Glastron MX 185 2011 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GT 185 2009 could be the deciding factor.
