Both the Premier Boats Grand Isle 250 RF 2012 and the Premier Boats S-Series 235 ES 2009 are pontoon designs, both built in aluminium, so 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 - Premier Boats Grand Isle 250 RF 2012 at 25,4 ft versus Premier Boats S-Series 235 ES 2009 at 24,0 ft. At 2 950 lbs and 2 900 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.

Both boats share a closely matched power ceiling - 225 hp for the Premier Boats Grand Isle 250 RF 2012 and 225 hp for the Premier Boats S-Series 235 ES 2009. 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. Fuel capacity breaks the other way: the Premier Boats Grand Isle 250 RF 2012 carries 47 gallons versus 29 gallons in the Premier Boats S-Series 235 ES 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Premier Boats Grand Isle 250 RF 2012 is rated for 16 passengers, while the Premier Boats S-Series 235 ES 2009 caps at 15. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Premier Boats Grand Isle 250 RF 2012 could be the deciding factor.

One place where both boats are genuinely identical is tube construction: both run 3 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.
