Both the Premier Boats Boundary Waters 310 SD 2012 and the Premier Boats Solaris 180 2013 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?

Size is the most obvious dividing line here. The Premier Boats Boundary Waters 310 SD 2012 measures 31,3 feet overall (2012), giving it roughly 12,9 additional feet of deck space compared to the Premier Boats Solaris 180 2013 at 18,4 feet (2013). Weight tells a clearer story for trailering families: the Premier Boats Boundary Waters 310 SD 2012 tips the scales at 4 900 lbs - 3 150 lbs more than the Premier Boats Solaris 180 2013 at 1 750 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 350 hp, the Premier Boats Boundary Waters 310 SD 2012 has a 275-hp advantage over the Premier Boats Solaris 180 2013's 75-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 25 gal and 25 gal - so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Premier Boats Boundary Waters 310 SD 2012 is rated for 20 passengers, while the Premier Boats Solaris 180 2013 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Premier Boats Boundary Waters 310 SD 2012 could be the deciding factor.

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