When two boats share the same hull type — in this case both the Glastron GLS 215 2009 and the Glastron GS 249 2012 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 2009 at 21,0 ft versus Glastron GS 249 2012 at 24,0 ft. Weight tells a clearer story for trailering families: the Glastron GS 249 2012 tips the scales at 4 437 lbs — 4 104 lbs less than the Glastron GLS 215 2009 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 GS 249 2012 tops out at 300 hp. Engine specs for the Glastron GLS 215 2009 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Glastron GS 249 2012 carries 56 gallons versus 34 gallons in the Glastron GLS 215 2009. 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 GS 249 2012 is rated for 10 passengers, while the Glastron GLS 215 2009 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GS 249 2012 could be the deciding factor.
