When two boats share the same hull type — in this case both the Polar Kraft 186 SC 2009 and the Polar Kraft Frontier 189 WT 2013 are modified vee 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?

On paper these two are close siblings in the size department — Polar Kraft 186 SC 2009 at 18,0 ft versus Polar Kraft Frontier 189 WT 2013 at 18,9 ft. Weight tells a clearer story for trailering families: the Polar Kraft 186 SC 2009 tips the scales at 1 184 lbs — 1 036 lbs more than the Polar Kraft Frontier 189 WT 2013 at 148 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 Polar Kraft Frontier 189 WT 2013 has a 35-hp advantage over the Polar Kraft 186 SC 2009's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Polar Kraft 186 SC 2009 carries 27 gallons versus 23 gallons in the Polar Kraft Frontier 189 WT 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 7 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
