Matching a flat Alumacraft Fisherman 160 CS 2011 against a deep vee Alumacraft Navigator 175 Sport 2010 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 — Alumacraft Fisherman 160 CS 2011 at 16,5 ft versus Alumacraft Navigator 175 Sport 2010 at 17,7 ft. Weight tells a clearer story for trailering families: the Alumacraft Navigator 175 Sport 2010 tips the scales at 1 357 lbs — 735 lbs less than the Alumacraft Fisherman 160 CS 2011 at 622 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 Alumacraft Navigator 175 Sport 2010 has a 110-hp advantage over the Alumacraft Fisherman 160 CS 2011's 40-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Both boats are rated for 5 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 Alumacraft Navigator 175 Sport 2010 comes in at 9 lbs per hp versus 16 lbs per hp for the Alumacraft Fisherman 160 CS 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.
