When two boats share the same hull type — in this case both the Glastron GTS 205 CB 2013 and the Glastron SSV 170 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 CB 2013 measures 20,5 feet overall (2013), giving it roughly 4,5 additional feet of deck space compared to the Glastron SSV 170 2009 at 16,0 feet (2009). At 22 lbs and 12 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.

Both boats are rated for 7 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
