When two boats share the same hull type — in this case both the Berkshire Pontoons 261XB 2010 and the Berkshire Pontoons STS 190CL 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?

Size is the most obvious dividing line here. The Berkshire Pontoons 261XB 2010 measures 26,4 feet overall (2010), giving it roughly 5,8 additional feet of deck space compared to the Berkshire Pontoons STS 190CL 2013 at 20,6 feet (2013). At 225 lbs and 195 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 power gap is worth calling out. Rated to 150 hp, the Berkshire Pontoons 261XB 2010 has a 60-hp advantage over the Berkshire Pontoons STS 190CL 2013's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Berkshire Pontoons 261XB 2010 is rated for 15 passengers, while the Berkshire Pontoons STS 190CL 2013 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Berkshire Pontoons 261XB 2010 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.
