When two boats share the same hull type — in this case both the Glastron GS 249 2012 and the Glastron GTS 225 2013 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 GS 249 2012 at 24,0 ft versus Glastron GTS 225 2013 at 22,0 ft. Weight tells a clearer story for trailering families: the Glastron GS 249 2012 tips the scales at 4 437 lbs — 4 404 lbs more than the Glastron GTS 225 2013 at 33 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 GS 249 2012 carries a rated maximum of 300 hp. Engine data for the Glastron GTS 225 2013 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Glastron GS 249 2012 carries 56 gallons versus 4 gallons in the Glastron GTS 225 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Glastron GTS 225 2013 is rated for 11 passengers, while the Glastron GS 249 2012 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GTS 225 2013 could be the deciding factor.
