When two boats share the same hull type — in this case both the Glastron GT 205 2011 and the Glastron GT 225 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?

On paper these two are close siblings in the size department — Glastron GT 205 2011 at 20,7 ft versus Glastron GT 225 2009 at 21,0 ft. Weight tells a clearer story for trailering families: the Glastron GT 205 2011 tips the scales at 275 lbs — 272 lbs more than the Glastron GT 225 2009 at 3 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 GT 205 2011 carries a rated maximum of 270 hp. Engine data for the Glastron GT 225 2009 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Both carry nearly identical fuel loads — 35 gal and 35 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Glastron GT 205 2011 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 GT 205 2011 could be the deciding factor.
