When two boats share the same hull type — in this case both the Glastron GS 289 2009 and the Glastron GT 185 2009 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?

Size is the most obvious dividing line here. The Glastron GS 289 2009 measures 28,0 feet overall (2009), giving it roughly 10,0 additional feet of deck space compared to the Glastron GT 185 2009 at 18,0 feet (2009). Weight tells a clearer story for trailering families: the Glastron GT 185 2009 tips the scales at 2 315 lbs — 2 250 lbs less than the Glastron GS 289 2009 at 65 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.

Both boats are rated for 8 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
