When two boats share the same hull type — in this case both the Glastron GLS 215 2013 and the Glastron GS 279 2008 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 279 2008 measures 27,0 feet overall (2008), giving it roughly 5,7 additional feet of deck space compared to the Glastron GLS 215 2013 at 21,3 feet (2013). Weight tells a clearer story for trailering families: the Glastron GS 279 2008 tips the scales at 6 225 lbs — 5 892 lbs less than the Glastron GLS 215 2013 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 279 2008 tops out at 320 hp. Engine specs for the Glastron GLS 215 2013 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Glastron GS 279 2008 carries 72 gallons versus 4 gallons in the Glastron GLS 215 2013. 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 279 2008 is rated for 8 passengers, while the Glastron GLS 215 2013 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 279 2008 could be the deciding factor.
