When two boats share the same hull type — in this case both the Glastron GT 205 2008 and the Glastron GTS 205 CB 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?

Size is the most obvious dividing line here. The Glastron GTS 205 CB 2013 measures 20,5 feet overall (2013), giving it roughly 18,5 additional feet of deck space compared to the Glastron GT 205 2008 at 2,0 feet (2008). Weight tells a clearer story for trailering families: the Glastron GT 205 2008 tips the scales at 278 lbs — 256 lbs more than the Glastron GTS 205 CB 2013 at 22 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 2008 carries a rated maximum of 270 hp. Engine data for the Glastron GTS 205 CB 2013 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 32 gal — so range won't be a tiebreaker here.
