Glastron GLS 235 2011 vs Glastron GTD 240 2020 — Same Brand, Different Boat

The Glastron GLS 235 2011 vs Glastron GTD 240 2020 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

The Glastron GLS 235 2011 carries a rated maximum of 300 hp. Engine data for the Glastron GTD 240 2020 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.

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 GTD 240 2020 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.

Bottom line: Choose the Glastron GLS 235 2011 if your priority is putting more people on the water — it handles 12 passengers and at 23,8 ft it has the deck room to back that rating up comfortably. The Glastron GTD 240 2020 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
