When two boats share the same hull type — in this case both the Glastron GLS 215 2011 and the Glastron GS 259 SC 2010 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 GS 259 SC 2010 measures 24,8 feet overall (2010), giving it roughly 3,5 additional feet of deck space compared to the Glastron GLS 215 2011 at 21,3 feet (2011). Weight tells a clearer story for trailering families: the Glastron GS 259 SC 2010 tips the scales at 545 lbs — 212 lbs less than the Glastron GLS 215 2011 at 333 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 2011 carries a rated maximum of 300 hp. Engine data for the Glastron GS 259 SC 2010 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Glastron GS 259 SC 2010 carries 56 gallons versus 34 gallons in the Glastron GLS 215 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 10 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
