When two boats share the same hull type — in this case both the Glastron DS 215 2013 and the Glastron GT 185 Ski & Fish 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 DS 215 2013 at 20,9 ft versus Glastron GT 185 Ski & Fish 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Glastron GT 185 Ski & Fish 2009 tips the scales at 2 335 lbs — 2 299 lbs less than the Glastron DS 215 2013 at 36 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.

For family outings this is probably the sharpest distinction between the two. The Glastron DS 215 2013 is rated for 13 passengers, while the Glastron GT 185 Ski & Fish 2009 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron DS 215 2013 could be the deciding factor.
