Glastron GLS 235 2009 vs Glastron GLS 235 2011 — A Close Look at Two Deep Vees

When two boats share the same hull type — in this case both the Glastron GLS 235 2009 and the Glastron GLS 235 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 GLS 235 2009 at 23,0 ft versus Glastron GLS 235 2011 at 23,8 ft. At 408 lbs and 408 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 GLS 235 2011 tops out at 300 hp. Engine specs for the Glastron GLS 235 2009 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 56 gal and 56 gal — so range won't be a tiebreaker here.

Both boats are rated for 12 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Glastron GLS 235 2009 and Glastron GLS 235 2011 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Glastron GLS 235 2009 vs Glastron GLS 235 2011 — Common Questions

Which is the larger boat — the Glastron GLS 235 2009 or the Glastron GLS 235 2011?
The Glastron GLS 235 2011 is the longer of the two at 23,8 feet overall. The Glastron GLS 235 2009 comes in at 23,0 feet, making it roughly 0,8 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Glastron GLS 235 2009 or the Glastron GLS 235 2011?
For trailering, the Glastron GLS 235 2011 has the edge at 408 lbs dry weight versus 408 lbs for the Glastron GLS 235 2009. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
What is the maximum horsepower rating for these boats?
The Glastron GLS 235 2011 has a documented max rating of 300 hp. Engine specifications for the Glastron GLS 235 2009 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Glastron GLS 235 2009 is Coast Guard rated for 12 passengers, while the Glastron GLS 235 2011 is certified for 12. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Glastron GLS 235 2009 and Glastron GLS 235 2011 share an 102 in. (2.59 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
How do the fuel tanks compare on the Glastron GLS 235 2009 and Glastron GLS 235 2011?
Both boats carry similar fuel loads — 56 gallons and 56 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Glastron GLS 235 2009 and Glastron GLS 235 2011 from the same manufacturer?
Yes — both the Glastron GLS 235 2009 and the Glastron GLS 235 2011 are built by Glastron. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
