Both the Glastron GLS 215 2011 and the Glastron GT 205 Ski & Fish 2008 are deep-V designs, both built in fibreglass, so 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 2011 at 21,3 ft versus Glastron GT 205 Ski & Fish 2008 at 20,0 ft. Weight tells a clearer story for trailering families: the Glastron GLS 215 2011 tips the scales at 3 330 lbs - 550 lbs more than the Glastron GT 205 Ski & Fish 2008 at 2 780 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 power gap is worth calling out. Rated to 300 hp, the Glastron GLS 215 2011 has a 30-hp advantage over the Glastron GT 205 Ski & Fish 2008's 270-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 34 gal and 35 gal - so range won't be a tiebreaker here.

The Glastron GLS 215 2011 is rated for up to 10 people. Passenger data for the Glastron GT 205 Ski & Fish 2008 wasn't available.
