When two boats share the same hull type — in this case both the Glastron GT 185 2013 and the Glastron SSV 170 2011 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 GT 185 2013 at 18,0 ft versus Glastron SSV 170 2011 at 16,9 ft. At 24 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.

The Glastron SSV 170 2011 tops out at 115 hp. Engine specs for the Glastron GT 185 2013 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 24 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 GT 185 2013 is rated for 8 passengers, while the Glastron SSV 170 2011 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GT 185 2013 could be the deciding factor.
