Glastron GLS 255 2010 vs Glastron GT 185 2008 — Which Deep Vee Fits Your Needs?

When two boats share the same hull type — in this case both the Glastron GLS 255 2010 and the Glastron GT 185 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 GLS 255 2010 measures 25,3 feet overall (2010), giving it roughly 7,3 additional feet of deck space compared to the Glastron GT 185 2008 at 18,0 feet (2008). Weight tells a clearer story for trailering families: the Glastron GT 185 2008 tips the scales at 2 315 lbs — 2 269 lbs less than the Glastron GLS 255 2010 at 46 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 GT 185 2008 tops out at 190 hp. Engine specs for the Glastron GLS 255 2010 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Glastron GLS 255 2010 carries 56 gallons versus 23 gallons in the Glastron GT 185 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Glastron GLS 255 2010 is rated for up to 12 people. Passenger data for the Glastron GT 185 2008 wasn't available.

Bottom line: The Glastron GLS 255 2010 at 25,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Glastron GT 185 2008 at 18,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
