Both the Premier Boats Grand Isle 260 RF / SL 2012 and the Premier Boats S-Series 250 2012 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 260 RF / SL 2012 at 26,4 ft versus Premier Boats S-Series 250 2012 at 25,4 ft. Weight tells a clearer story for trailering families: the Premier Boats Grand Isle 260 RF / SL 2012 tips the scales at 3 350 lbs - 400 lbs more than the Premier Boats S-Series 250 2012 at 2 950 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.

The power gap is worth calling out. Rated to 250 hp, the Premier Boats Grand Isle 260 RF / SL 2012 has a 25-hp advantage over the Premier Boats S-Series 250 2012's 225-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 47 gal and 47 gal - so range won't be a tiebreaker here.

Both boats are rated for 16 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

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.
