Both the Premier Boats Boundary Waters 310 2013 and the Premier Boats SunSation LTD 160 RE 2009 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 2013 measures 31,4 feet overall (2013), giving it roughly 16,4 additional feet of deck space compared to the Premier Boats SunSation LTD 160 RE 2009 at 15,0 feet (2009). Weight tells a clearer story for trailering families: the Premier Boats Boundary Waters 310 2013 tips the scales at 3 650 lbs - 2 200 lbs more than the Premier Boats SunSation LTD 160 RE 2009 at 1 450 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 150 hp, the Premier Boats Boundary Waters 310 2013 has a 100-hp advantage over the Premier Boats SunSation LTD 160 RE 2009's 50-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Premier Boats SunSation LTD 160 RE 2009 carries 30 gallons versus 25 gallons in the Premier Boats Boundary Waters 310 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Premier Boats Boundary Waters 310 2013 is rated for 22 passengers, while the Premier Boats SunSation LTD 160 RE 2009 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 2013 could be the deciding factor.
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.
Bottom line: Choose the Premier Boats Boundary Waters 310 2013 if your priority is putting more people on the water - it handles 22 passengers and at 31,4 ft it has the deck room to back that rating up comfortably. The Premier Boats SunSation LTD 160 RE 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
