When two boats share the same hull type — in this case both the Berkshire Pontoons CTS 210CL - A 2013 and the Berkshire Pontoons STS 190CL - B 2013 are pontoon designs with aluminum 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?
The Berkshire Pontoons CTS 210CL - A 2013 carries a rated maximum of 115 hp. Engine data for the Berkshire Pontoons STS 190CL - B 2013 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 Berkshire Pontoons CTS 210CL - A 2013 is rated for 10 passengers, while the Berkshire Pontoons STS 190CL - B 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Berkshire Pontoons CTS 210CL - A 2013 could be the deciding factor.
One place where both boats are genuinely identical is tube construction: both run 2 aluminum tubes at 25" diameter. That shared spec means stability and buoyancy characteristics are closely matched — the ride difference you'll feel between them comes primarily from deck length, weight distribution, and motor choice.
Bottom line: Choose the Berkshire Pontoons CTS 210CL - A 2013 if your priority is putting more people on the water — it handles 10 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The Berkshire Pontoons STS 190CL - B 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
