When two boats share the same hull type — in this case both the Polar Kraft Modified V-Hull 1668 LW 2008 and the Polar Kraft MV 1680 DB 2010 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 Modified V-Hull 1668 LW 2008 at 15,0 ft versus Polar Kraft MV 1680 DB 2010 at 16,2 ft. Weight tells a clearer story for trailering families: the Polar Kraft MV 1680 DB 2010 tips the scales at 704 lbs — 426 lbs less than the Polar Kraft Modified V-Hull 1668 LW 2008 at 278 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 50 hp, the Polar Kraft MV 1680 DB 2010 has a 25-hp advantage over the Polar Kraft Modified V-Hull 1668 LW 2008's 25-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Both boats are rated for 4 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Polar Kraft Modified V-Hull 1668 LW 2008 comes in at 11 lbs per hp versus 14 lbs per hp for the Polar Kraft MV 1680 DB 2010. 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.
