When two boats share the same hull type — in this case both the Premier Boats Cast-A-Way 221 2013 and the Premier Boats S-Series 250 RE 2009 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 — Premier Boats Cast-A-Way 221 2013 at 22,4 ft versus Premier Boats S-Series 250 RE 2009 at 25,0 ft. Weight tells a clearer story for trailering families: the Premier Boats Cast-A-Way 221 2013 tips the scales at 205 lbs — 173 lbs more than the Premier Boats S-Series 250 RE 2009 at 32 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 S-Series 250 RE 2009 has a 135-hp advantage over the Premier Boats Cast-A-Way 221 2013's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 28 gal and 29 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Premier Boats S-Series 250 RE 2009 is rated for 15 passengers, while the Premier Boats Cast-A-Way 221 2013 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Premier Boats S-Series 250 RE 2009 could be the deciding factor.

Both are 23-tube and 3-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity — more so than most buyers realize when comparing on paper.
