When two boats share the same hull type — in this case both the Premier Boats Boundary Waters 275 2007 and the Premier Boats Explorer 171 2013 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 275 2007 measures 27,0 feet overall (2007), giving it roughly 9,6 additional feet of deck space compared to the Premier Boats Explorer 171 2013 at 17,4 feet (2013). At 35 lbs and 16 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 200 hp, the Premier Boats Boundary Waters 275 2007 has a 140-hp advantage over the Premier Boats Explorer 171 2013's 60-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 Explorer 171 2013 carries 28 gallons versus 3 gallons in the Premier Boats Boundary Waters 275 2007. 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 275 2007 is rated for 19 passengers, while the Premier Boats Explorer 171 2013 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Premier Boats Boundary Waters 275 2007 could be the deciding factor.
