When two boats share the same hull type — in this case both the Premier Boats Explorer 171 2009 and the Premier Boats SunSation 180 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 171 2009 at 17,0 ft versus Premier Boats SunSation 180 2010 at 18,0 ft. At 15 lbs and 15 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 — 60 hp for the Premier Boats Explorer 171 2009 and 60 hp for the Premier Boats SunSation 180 2010. 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 Premier Boats Explorer 171 2009 is rated for 9 passengers, while the Premier Boats SunSation 180 2010 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Premier Boats Explorer 171 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Premier Boats SunSation 180 2010 comes in at 0 lbs per hp versus 0 lbs per hp for the Premier Boats Explorer 171 2009. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Both are 2-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.
