When two boats share the same hull type — in this case both the Glastron MX 175 2008 and the Glastron SSV 170 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?

On paper these two are close siblings in the size department — Glastron MX 175 2008 at 17,0 ft versus Glastron SSV 170 2010 at 16,9 ft. Weight tells a clearer story for trailering families: the Glastron MX 175 2008 tips the scales at 228 lbs — 216 lbs more than the Glastron SSV 170 2010 at 12 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 share a closely matched power ceiling — 135 hp for the Glastron MX 175 2008 and 115 hp for the Glastron SSV 170 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 23 gal and 23 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Glastron SSV 170 2010 is rated for 7 passengers, while the Glastron MX 175 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron SSV 170 2010 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Glastron SSV 170 2010 comes in at 0 lbs per hp versus 2 lbs per hp for the Glastron MX 175 2008. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
