When two boats share the same hull type — in this case both the Premier Boats Boundary Waters 310 2007 and the Premier Boats SunSation X-Series 160 RE 2007 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?

Size is the most obvious dividing line here. The Premier Boats Boundary Waters 310 2007 measures 31,0 feet overall (2007), giving it roughly 16,0 additional feet of deck space compared to the Premier Boats SunSation X-Series 160 RE 2007 at 15,0 feet (2007). Weight tells a clearer story for trailering families: the Premier Boats SunSation X-Series 160 RE 2007 tips the scales at 875 lbs — 837 lbs less than the Premier Boats Boundary Waters 310 2007 at 38 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 Boundary Waters 310 2007 has a 200-hp advantage over the Premier Boats SunSation X-Series 160 RE 2007's 50-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 Boundary Waters 310 2007 is rated for 23 passengers, while the Premier Boats SunSation X-Series 160 RE 2007 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 Boundary Waters 310 2007 could be the deciding factor.
