When two boats share the same hull type — in this case both the Premier Boats Solaris 180 2012 and the Premier Boats SunSpree 180 2008 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 Solaris 180 2012 at 18,4 ft versus Premier Boats SunSpree 180 2008 at 18,0 ft. Weight tells a clearer story for trailering families: the Premier Boats Solaris 180 2012 tips the scales at 175 lbs — 166 lbs more than the Premier Boats SunSpree 180 2008 at 9 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.

Both boats share a closely matched power ceiling — 75 hp for the Premier Boats Solaris 180 2012 and 60 hp for the Premier Boats SunSpree 180 2008. 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.

Both boats are rated for 9 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.

Both are 23-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.
