When two boats share the same hull type — in this case both the Premier Boats Explorer 221 2007 and the Premier Boats SunSation 220 FS 2010 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 Explorer 221 2007 at 22,0 ft versus Premier Boats SunSation 220 FS 2010 at 22,0 ft. At 21 lbs and 23 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 115 hp, the Premier Boats Explorer 221 2007 has a 25-hp advantage over the Premier Boats SunSation 220 FS 2010'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 Premier Boats SunSation 220 FS 2010 is rated for 10 passengers, while the Premier Boats Explorer 221 2007 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Premier Boats SunSation 220 FS 2010 could be the deciding factor.
Bottom line: Choose the Premier Boats SunSation 220 FS 2010 if your priority is putting more people on the water — it handles 10 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The Premier Boats Explorer 221 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
