When two boats share the same hull type — in this case both the Glastron GLS 215 2012 and the Glastron GT 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 GLS 215 2012 at 21,3 ft versus Glastron GT 225 2013 at 22,0 ft. Weight tells a clearer story for trailering families: the Glastron GLS 215 2012 tips the scales at 333 lbs — 300 lbs more than the Glastron GT 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 GLS 215 2012 carries a rated maximum of 300 hp. Engine data for the Glastron GT 225 2013 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Both carry nearly identical fuel loads — 4 gal and 4 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Glastron GT 225 2013 is rated for 11 passengers, while the Glastron GLS 215 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 GT 225 2013 could be the deciding factor.
