When two boats share the same hull type — in this case both the Glastron GS 209 CC 2010 and the Glastron GT 249 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 GT 249 2009 measures 24,0 feet overall (2009), giving it roughly 3,8 additional feet of deck space compared to the Glastron GS 209 CC 2010 at 20,2 feet (2010). Weight tells a clearer story for trailering families: the Glastron GT 249 2009 tips the scales at 4 437 lbs — 1 605 lbs less than the Glastron GS 209 CC 2010 at 2 832 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 GS 209 CC 2010 is rated for 8 passengers, while the Glastron GT 249 2009 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GS 209 CC 2010 could be the deciding factor.
