When two boats share the same hull type — in this case both the Glastron GS 289 2012 and the Glastron GT 180 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?

Size is the most obvious dividing line here. The Glastron GS 289 2012 measures 28,8 feet overall (2012), giving it roughly 11,8 additional feet of deck space compared to the Glastron GT 180 2011 at 17,1 feet (2011). At 65 lbs and 15 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 400 hp, the Glastron GS 289 2012 has a 250-hp advantage over the Glastron GT 180 2011's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Glastron GS 289 2012 carries 84 gallons versus 23 gallons in the Glastron GT 180 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

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.
