When two boats share the same hull type — in this case both the Polar Kraft 186 SC 2008 and the Polar Kraft Frontier 179 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 2008 at 18,0 ft versus Polar Kraft Frontier 179 WT 2013 at 17,9 ft. Weight tells a clearer story for trailering families: the Polar Kraft 186 SC 2008 tips the scales at 1 184 lbs — 1 060 lbs more than the Polar Kraft Frontier 179 WT 2013 at 124 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 — 115 hp for the Polar Kraft 186 SC 2008 and 135 hp for the Polar Kraft Frontier 179 WT 2013. 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. Fuel capacity breaks the other way: the Polar Kraft 186 SC 2008 carries 27 gallons versus 23 gallons in the Polar Kraft Frontier 179 WT 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 Polar Kraft 186 SC 2008 is rated for 7 passengers, while the Polar Kraft Frontier 179 WT 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Polar Kraft 186 SC 2008 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Polar Kraft Frontier 179 WT 2013 comes in at 1 lbs per hp versus 10 lbs per hp for the Polar Kraft 186 SC 2008. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Choose the Polar Kraft 186 SC 2008 if your priority is putting more people on the water — it handles 7 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Polar Kraft Frontier 179 WT 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
