When two boats share the same hull type — in this case both the Berkshire Pontoons 261 E BP3 Premium 2012 and the Berkshire Pontoons STS 233SLX BP3 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?

On paper these two are close siblings in the size department — Berkshire Pontoons 261 E BP3 Premium 2012 at 26,8 ft versus Berkshire Pontoons STS 233SLX BP3 2013 at 24,0 ft. Weight tells a clearer story for trailering families: the Berkshire Pontoons 261 E BP3 Premium 2012 tips the scales at 367 lbs — 341 lbs more than the Berkshire Pontoons STS 233SLX BP3 2013 at 26 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 Berkshire Pontoons 261 E BP3 Premium 2012 and 300 hp for the Berkshire Pontoons STS 233SLX BP3 2013. 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.

For family outings this is probably the sharpest distinction between the two. The Berkshire Pontoons 261 E BP3 Premium 2012 is rated for 16 passengers, while the Berkshire Pontoons STS 233SLX BP3 2013 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Berkshire Pontoons 261 E BP3 Premium 2012 could be the deciding factor.

Both are 3-tube and 2-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity — more so than most buyers realize when comparing on paper.
