When two boats share the same hull type — in this case both the Glastron GLS 235 2011 and the Glastron GS 259 2008 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 GLS 235 2011 at 23,8 ft versus Glastron GS 259 2008 at 24,0 ft. Weight tells a clearer story for trailering families: the Glastron GS 259 2008 tips the scales at 5 525 lbs — 5 117 lbs less than the Glastron GLS 235 2011 at 408 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 — 300 hp for the Glastron GLS 235 2011 and 320 hp for the Glastron GS 259 2008. 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 — 56 gal and 56 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Glastron GLS 235 2011 is rated for 12 passengers, while the Glastron GS 259 2008 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GLS 235 2011 could be the deciding factor.
