Matching a deep vee Polar Kraft Kodiak Sport 170 FS 2013 against a modified vee Polar Kraft MV 1680 DB 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 Kodiak Sport 170 FS 2013 at 17,1 ft versus Polar Kraft MV 1680 DB 2011 at 16,2 ft. Weight tells a clearer story for trailering families: the Polar Kraft MV 1680 DB 2011 tips the scales at 704 lbs — 568 lbs less than the Polar Kraft Kodiak Sport 170 FS 2013 at 136 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 Kodiak Sport 170 FS 2013 has a 100-hp advantage over the Polar Kraft MV 1680 DB 2011's 50-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 Kodiak Sport 170 FS 2013 is rated for 6 passengers, while the Polar Kraft MV 1680 DB 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Polar Kraft Kodiak Sport 170 FS 2013 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Polar Kraft Kodiak Sport 170 FS 2013 comes in at 1 lbs per hp versus 14 lbs per hp for the Polar Kraft MV 1680 DB 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.
