When two boats share the same hull type — in this case both the Polar Kraft 186 T 2008 and the Polar Kraft Nor'Easter V 163 T 2012 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 T 2008 at 18,0 ft versus Polar Kraft Nor'Easter V 163 T 2012 at 16,5 ft. At 1 124 lbs and 1 075 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.
Both boats share a closely matched power ceiling — 75 hp for the Polar Kraft 186 T 2008 and 75 hp for the Polar Kraft Nor'Easter V 163 T 2012. 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. Both carry nearly identical fuel loads — 27 gal and 27 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Polar Kraft 186 T 2008 is rated for 7 passengers, while the Polar Kraft Nor'Easter V 163 T 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Polar Kraft 186 T 2008 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Polar Kraft Nor'Easter V 163 T 2012 comes in at 14 lbs per hp versus 15 lbs per hp for the Polar Kraft 186 T 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 T 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 Nor'Easter V 163 T 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
