When two boats share the same hull type — in this case both the Glastron GTS 205 2013 and the Glastron SSV 175 2009 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 GTS 205 2013 measures 20,5 feet overall (2013), giving it roughly 3,5 additional feet of deck space compared to the Glastron SSV 175 2009 at 17,0 feet (2009). At 277 lbs and 204 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.

For family outings this is probably the sharpest distinction between the two. The Glastron GTS 205 2013 is rated for 9 passengers, while the Glastron SSV 175 2009 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GTS 205 2013 could be the deciding factor.
