When two boats share the same hull type — in this case both the Glastron GLS 215 2011 and the Glastron GLS 235 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?

On paper these two are close siblings in the size department — Glastron GLS 215 2011 at 21,3 ft versus Glastron GLS 235 2010 at 23,8 ft. At 333 lbs and 408 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The Glastron GLS 215 2011 carries a rated maximum of 300 hp. Engine data for the Glastron GLS 235 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 GLS 235 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.

For family outings this is probably the sharpest distinction between the two. The Glastron GLS 235 2010 is rated for 12 passengers, while the Glastron GLS 215 2011 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GLS 235 2010 could be the deciding factor.
