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

On paper these two are close siblings in the size department — Glastron MX 175 2008 at 17,0 ft versus Glastron SSV 175 2009 at 17,0 ft. At 228 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.

The Glastron MX 175 2008 carries a rated maximum of 135 hp. Engine data for the Glastron SSV 175 2009 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.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 175 2009 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 175 2009 could be the deciding factor.
