When two boats share the same hull type — in this case both the Premier Boats Boundary Waters 310 RE 2011 and the Premier Boats SunSation LTD 250 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?

Size is the most obvious dividing line here. The Premier Boats Boundary Waters 310 RE 2011 measures 31,3 feet overall (2011), giving it roughly 7,3 additional feet of deck space compared to the Premier Boats SunSation LTD 250 2008 at 24,0 feet (2008). Weight tells a clearer story for trailering families: the Premier Boats Boundary Waters 310 RE 2011 tips the scales at 405 lbs — 160 lbs more than the Premier Boats SunSation LTD 250 2008 at 245 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 — 150 hp for the Premier Boats Boundary Waters 310 RE 2011 and 150 hp for the Premier Boats SunSation LTD 250 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.

For family outings this is probably the sharpest distinction between the two. The Premier Boats Boundary Waters 310 RE 2011 is rated for 21 passengers, while the Premier Boats SunSation LTD 250 2008 caps at 14. 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 RE 2011 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.
