Both the Glastron MX 180 2013 and the Glastron MX185 2013 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 MX 180 2013 at 17,1 ft versus Glastron MX185 2013 at 18,4 ft. Weight tells a clearer story for trailering families: the Glastron MX185 2013 tips the scales at 2 280 lbs - 330 lbs less than the Glastron MX 180 2013 at 1 950 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.
For family outings this is probably the sharpest distinction between the two. The Glastron MX 180 2013 is rated for 8 passengers, while the Glastron MX185 2013 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron MX 180 2013 could be the deciding factor.
Bottom line: Choose the Glastron MX 180 2013 if your priority is putting more people on the water - it handles 8 passengers and at 17,1 ft it has the deck room to back that rating up comfortably. The Glastron MX185 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
