When two boats share the same hull type — in this case both the Glastron GLS 215 2012 and the Glastron GTS 160 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 GLS 215 2012 measures 21,3 feet overall (2012), giving it roughly 4,8 additional feet of deck space compared to the Glastron GTS 160 CB 2013 at 16,5 feet (2013). Weight tells a clearer story for trailering families: the Glastron GLS 215 2012 tips the scales at 333 lbs — 320 lbs more than the Glastron GTS 160 CB 2013 at 13 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 GTS 160 CB 2013 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Glastron GTS 160 CB 2013 carries 12 gallons versus 4 gallons in the Glastron GLS 215 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Glastron GLS 215 2012 is rated for 10 passengers, while the Glastron GTS 160 CB 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GLS 215 2012 could be the deciding factor.
