When two boats share the same hull type — in this case both the Glastron GT 225 2009 and the Glastron GTS 229 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 GT 225 2009 at 21,0 ft versus Glastron GTS 229 2013 at 22,0 ft. At 3 lbs and 33 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.

For family outings this is probably the sharpest distinction between the two. The Glastron GTS 229 2013 is rated for 9 passengers, while the Glastron GT 225 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 GTS 229 2013 could be the deciding factor.
