When two boats share the same hull type — in this case both the Glastron GTS 205 CB 2013 and the Glastron SSV 175 2010 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 3,4 additional feet of deck space compared to the Glastron SSV 175 2010 at 17,1 feet (2010). Weight tells a clearer story for trailering families: the Glastron SSV 175 2010 tips the scales at 204 lbs — 182 lbs less than the Glastron GTS 205 CB 2013 at 22 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.

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.
