When two boats share the same hull type — in this case both the Glastron GT 160 CB 2012 and the Glastron GT 225 2011 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 GT 225 2011 measures 20,1 feet overall (2011), giving it roughly 3,6 additional feet of deck space compared to the Glastron GT 160 CB 2012 at 16,5 feet (2012). At 13 lbs and 3 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 power gap is worth calling out. Rated to 300 hp, the Glastron GT 225 2011 has a 185-hp advantage over the Glastron GT 160 CB 2012's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Glastron GT 225 2011 carries 35 gallons versus 12 gallons in the Glastron GT 160 CB 2012. 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 GT 225 2011 is rated for 10 passengers, while the Glastron GT 160 CB 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GT 225 2011 could be the deciding factor.
