Matching a modified vee Polar Kraft V 170 FS 2010 against a deep vee Polar Kraft V 1778 WB 2011 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Polar Kraft V 170 FS 2010 at 16,9 ft versus Polar Kraft V 1778 WB 2011 at 17,0 ft. At 13 lbs and 37 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 115 hp, the Polar Kraft V 170 FS 2010 has a 75-hp advantage over the Polar Kraft V 1778 WB 2011's 40-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Polar Kraft V 170 FS 2010 is rated for 6 passengers, while the Polar Kraft V 1778 WB 2011 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 V 170 FS 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Polar Kraft V 170 FS 2010 comes in at 0 lbs per hp versus 1 lbs per hp for the Polar Kraft V 1778 WB 2011. 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 V 170 FS 2010 if your priority is putting more people on the water — it handles 6 passengers and at 16,9 ft it has the deck room to back that rating up comfortably. The Polar Kraft V 1778 WB 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
